The Type 285 has over 2,000 units running currently in some of the world's largest liquid gas plants, proving its reliable performance. Doug Volden, Director, Marketing 2008-03-13 http://www.johncranetoday.com/login.cfm?storyid=180 Never before has there has been so much interest among ethylene producing plants to achieve maximum compressor reliability and product quality to comply with today's strict local and global emission standards. Joe Delrahim, Director Gas Seal Sales for Latin America 2008-03-13 http://www.johncranetoday.com/login.cfm?storyid=181 Founded in the early 1980s, the John Crane Academy is a unique industry resource responsible for the training and education of thousands of maintenance mechanics, rotating equipment engineers and related professionals. The Academy was founded to expand the knowledge and skill levels of customers interested in achieving maximum return on their mechanical seal investment. Marilyn Fischbach, Director of Training & Development 2008-03-13 http://www.johncranetoday.com/login.cfm?storyid=182 It goes without saying that maintaining equipment uptime in a mining operation is essential. But, for one of South America's largest mining organizations that processes sulfurated copper, reliability simply wasn't acceptable. That is why they turned to John Crane to develop a Pump Sealing System Improvement Program using the Six Sigma methodology. Jorge Correa, Operations Director, John Crane Latin America – Six Sigma Master Black Belt 2008-03-13 http://www.johncranetoday.com/login.cfm?storyid=183 According to Paul Richards, Marketing Specialist for John Crane, Carver Pump recently performed shock testing to discern how much destruction a pump and seal installed on a barge could withstand and still function properly. John Crane's Type 3710 split seal, made from Inconel® Alloy 625, was installed on the barge in a Carver Seawater Service Pump. Tom Evans, Marketing Manager 2008-03-13 http://www.johncranetoday.com/login.cfm?storyid=173 There is validity in numbers. Such is the case for John Crane's proprietary INTERFACE Reliability Management Software. Introduced in 1999 and currently being used around the world in 31 countries, the software recently reached the 200,000 unit milestone and has proven to be an effective and easy-to-use tool that organizes comprehensive plant performance data for all rotating equipment including pumps, mixers and agitators. Tim Reece, Director Performance Plus 2007-11-20 http://www.johncranetoday.com/login.cfm?storyid=174 By working cooperatively with global slurry pump and rotating equipment manufacturers, John Crane has optimized the Type 5860 heavy-duty slurry seal for slurry pumps, mixers and other pieces of rotating equipment used in the processing and transportation of difficult-to-seal slurries, ores and minerals. The result is a seal that better meets industry needs because of its rugged construction, long operating life and fault-free installation while requiring minimal support with low operating costs. Tom Evans, Marketing Manager 2007-11-20 http://www.johncranetoday.com/login.cfm?storyid=175 A common operating problem encountered with many single, dry running contacting face mechanical seals on mixers is audible running noise or face squeal. However, with the introduction of John Crane's intelli-faceTM technology, quiet operation is achieved. Mike Kalodimos, Chemical Market Sector Manager/2800 Series 2007-11-20 http://www.johncranetoday.com/login.cfm?storyid=176 In some cases, compression packing is used to seal light to medium duty pumps on applications that prove to be difficult for mechanical seals. The pump seal is formed by the packing being squeezed between the inboard end of the stuffing box and the gland. A common packing installation is shown in Figure 1 less the impellor. A static seal is formed at the ends of the packing rings and at the inside diameter of the stuffing box. The dynamic seal is formed between the packing and the shaft sleeve. Load applied to the packing deforms the packing against the shaft sleeve controlling leakage. Some leakage is necessary to cool and lubricate the packing. The amount of leakage will depend on the material of construction for the packing, operating conditions and the mechanical condition of the pump. The packing applied must be able to withstand the variables of the equipment such as runout, misalignments and thermal growth of the equipment without an appreciable increase in leakage. The number of rings may vary from application to application depending on the objective of the sealing system. A lantern ring is used on most applications to introduce a lubricant to the packing. Packing rings from the lantern ring to the bottom of the box seal the fluid being pumped. The packing rings between the gland and lantern ring seal the lubricant used with the system. 2007-11-20 http://www.johncranetoday.com/login.cfm?storyid=177 The proven savings in water usage and seal-related costs that result from the John Crane SmartFlow are the reasons cited for the product's recent selection as the Best Specific Environmental Initiative from the United Nations Association of Australia 2007 World Environment Day Awards. Tom Evans, Marketing Manager 2007-11-20 http://www.johncranetoday.com/login.cfm?storyid=167 During the last two years, John Crane has invested approximately $10 million (£5 million) and built a dedicated team of experts to deliver the next generation of sealing products for the Turbomachinery industry. The first of these new products is a new high pressure variant of the Type 28 EXP. This seal features a silicon carbide stationary face, which is specially designed for today's high pressure applications. The new hard face uses a solid silicon carbide material, which is then coated with a diamond like coating (DLC). The silicon carbide material provides a high modulus, limiting pressure deflection while the coating minimizes friction and maximizes wear performance. Emery Johnson, Sales Director Dry Gas Seals, North America 2007-08-30 http://www.johncranetoday.com/login.cfm?storyid=168 As today's oil and gas industry continues to respond to the changing dynamics of a world economy, there is little argument that compressor reliability and uninterrupted operation are paramount and crucial to plant operation. One proven means to improve reliability is the integration of dry gas seal technology. Established as a solution for almost three decades on thousands of installed bases, the dry gas seal improves compressor and plant reliability, as well as product quality. However, the key to success is minimizing face contact for these seals. In many cases condensate causes these seals to fail, especially when a plant reliability team does not have a thorough understanding of the seal's operating environment. Such challenges are typically avoidable though, with proper understanding of the scenarios that cause condensate. Joe Delrahim, Sales Director Dry Gas Seals, Latin America 2007-08-30 http://www.johncranetoday.com/login.cfm?storyid=169 John Crane recently designed and developed gas seals for the world's largest liquefied natural gas compressor. The project for a large LNG producer in the Middle East demanded high levels of expertise from John Crane's gas seals team, who worked in partnership with compressor manufacturers and the end-user to ensure the specially designed seals would meet a variety of demands. Simon Outhwaite, General Manager, Gas Seals Group, Europe, Africa and Asia 2007-08-30 http://www.johncranetoday.com/login.cfm?storyid=170 John Crane's Turbomachinery Group has invested $4.8 million (£2.4 million) in state-of-the-art seal testing facilities. The investment includes the company's global test bay facilities in Slough (UK), which were upgraded to double the amount of seals tested. Dave Hill, Director of Turbomachinery and International Projects, Europe, Africa and Asia 2007-08-30 http://www.johncranetoday.com/login.cfm?storyid=171 John Crane's $4.8 million (£2.4 million) Turbomachinery Group investment program is already bringing direct benefits to customers with the formation of a new Gas Seals Reliability Group, tasked with helping customers maximize the reliability of their seals and ultimately reduce costs. Ian Goldswain, Director of New Business Development, Dry Gas Seals, Europe, Africa and Asia 2007-08-30 http://www.johncranetoday.com/login.cfm?storyid=172 A major cause of pump failure is mechanical seal leakage. John Crane offers a comprehensive poster and guide for diagnosing the 12 most common causes of seal failure.

Specific topics include: Tom Evans, Power Generation Manager 2007-01-10 http://www.johncranetoday.com/login.cfm?storyid=164 John Crane has signed an exclusive distribution and licensing agreement with ISOMAG Corp. that provides them with the right to market and manufacture ISOMAG magnetic bearing seals globally. The ISOMAG patented magnetic bearing face seal technology provides proven performance benefits versus conventional lip seals and labyrinth-type isolators. With standard and engineered designs to fit most rotating equipment, the ISOMAG bearing seal is a compact face seal utilizing built-in magnetic attraction rather than springs or bellows to hold the faces together. Mike Kraus, Marketing Manager 2007-01-10 http://www.johncranetoday.com/login.cfm?storyid=165 In today's global marketplace, it is crucial to have a partner that is where you are, wherever and whenever that may be. That is why John Crane launched the International Projects Group - a team of dedicated professionals charged with advisory and project coordination capabilities from design and engineering to manufacturing, testing, installation and training. You'll benefit from a single source contact, early collaboration, close coordination and extensive project management. Rick Page, Vice President, Marketing 2007-01-10 http://www.johncranetoday.com/login.cfm?storyid=158 John Crane Inc. has announced its long-running collaboration with Advanced Diamond Technologies, Inc. (ADT) to develop and commercialize Ultrananocrystalline Diamond (UNCD) as a means to dramatically improve the friction and wear characteristics of mechanical seal faces. John Crane is now working with selected customers to validate the ability of UNCD enhanced seal faces to improve mechanical seal reliability and performance in demanding applications. Rick Page, VP Marketing 2006-10-11 http://www.johncranetoday.com/login.cfm?storyid=159 Heat exchangers serve a vital role in mechanical seal applications because they cool the product flush, which extends the life of the mechanical seal and the Mean Time Between Repair (MTBR). Primarily for use in API Plan 21 and 23 applications, John Crane water-cooled heat exchangers are available in four different sizes to ensure the most efficient solution for each application. Unlike other heat exchangers, John Crane's solution has the product flow on the tube side and the cool water on the shell side. Kenneth Mackay, Sales and Marketing Manager 2006-10-11 http://www.johncranetoday.com/login.cfm?storyid=160 Over the years, sealing technology has produced a host of different sealing concepts, each of which has met with varying degrees of success. Designs such as labyrinth seals, carbon ring seals, bushing seals, and circumferential seals have all been considered viable options for certain applications; however, their use often comes with limits on speed, pressure and operating conditions, and, with changes in condition, they are prone to problems such as leakage and relatively short periods of operation. All of this changed in the 1960s when John Crane Inc. introduced the world to a revolutionary new piece of sealing technology-the non-contacting dry gas seal. The seal uses a spiral groove seal face with a sealing dam on the inside diameter to provide resistance to gas flow and allow pressure to build up at the bottom of each groove, separating the seal faces. This separation allows a small amount of gas to flow across the seal faces and keep them cool and non-contacting, thereby minimizing the detrimental effects friction can have on a seal face. Paul Hosking, Director Type 28 Dry Gas Seals 2006-10-11 http://www.johncranetoday.com/login.cfm?storyid=153 John Crane has received a Top Supplier Performer Award for 2005 from Goulds Pumps Inc., a subsidiary of ITT Corporation. Guy Woodworth, Director EOEM Sales 2006-05-25 http://www.johncranetoday.com/login.cfm?storyid=154 Water used in the diverse industries served by John Crane varies in source from river water to a wide variety of treated waters. Regardless of the source, impurities present in water used by power, water treatment, wastewater and ethanol plants, as well as other industries, cause problems by forming deposits on components and equipment surfaces, thus impairing heat transfer, fluid flow and overall process efficiency. These deposits also contribute to corrosion of metal surfaces. Mike Kraus, John Crane Market Development Manager 2006-05-25 http://www.johncranetoday.com/login.cfm?storyid=155 Since the first half of 2005, John Crane Italy, with collaboration from the John Crane Morton Grove Packing Division, took on the challenge of promoting Valve Live Loading in the Italian petrochemical, oil and gas industries. Alfred Cooper, Valve Packing Live Load Expert 2006-05-25 http://www.johncranetoday.com/login.cfm?storyid=156 John Crane has announced the introduction of the new API 682 High-temperature Cartridge Seals. These seals will extend the Mean Time Between Repairs (MTBR) as compared with conventional seals in high-temperature environments. Doug Volden, Marketing Director 2006-05-25 http://www.johncranetoday.com/login.cfm?storyid=145 Since the introduction of the new generation of dependable high-temperature Corrosive (HTC) resistant mechanical seals, approximately 1,000 HTC seal heads have been supplied for single and dual high-temperature cartridge seals with seal sizes ranging from 1.75" to 7.00". These dependable High-Temperature seals utilize an innovative design technology to reliably seal high-temperature process fluids on rotating equipment. Proven on difficult applications at a number of the world's largest oil refineries, these seals will extend the Mean Time Between Repairs (MTBR) as compared with conventional seals in high-temperature and extremely corrosive environments. Jesse Fordyce, Oil & Gas Market Manager 2006-02-24 http://www.johncranetoday.com/login.cfm?storyid=146 Recognized as a useful substance for hundreds of years, natural gas is one of the main sources of energy for today's day-to-day needs and activities. And, with the increased focus on the environment, lean initiatives and sustainable solutions, natural gas continues to grow as a solution. Not only is it efficient, but natural gas is readily available, easy to transport, and most important — clean. In response to its growing acceptance as well as environmental demands, power plants have integrated natural gas as a means to run their gas turbines, which in turn powers the generator in order to produce power — all in a clean fashion. Keeping other components — such as the all important compressor — free of contaminants is essential. As such, there is little argument that compressor reliability and uninterrupted operation are paramount and crucial to plant operation. Although there are countless vendors and compressor sizes continue to increase and their specifications advance, spare compressors simply aren't an option for most because of their cost. Further, operating requirements, such as pressure rating and speed, continue to expand beyond original intent, resulting in compressors being taxed beyond their design capabilities. One means to improve reliability though is with the integration of dry gas seal technology. Proven as a solution for almost two decades on thousands of installed bases, the dry gas seal has been shown to improve compressor and plant reliability, as well as product quality. However, key to success in achieving optimum reliability is selection of the right dry gas seal and control system as well as a commitment to training and commissioning/operational procedures. Joe Delrahim, Marketing Manager 2006-02-24 http://www.johncranetoday.com/login.cfm?storyid=148 The popular John Crane Academy seminars are now available online. A unique industry resource responsible for the training of thousands of professionals, the Academy was founded to expand the knowledge and skill levels of customers interested in achieving maximum return on their mechanical seal investment. Marilyn Fischbach, Director of Training 2006-02-24 http://www.johncranetoday.com/login.cfm?storyid=149 John Crane has developed a live-loaded mechanical packing cartridge seal — the Type LMPC seal — for static or dynamic sealing applications. The one-piece seal is mechanically loaded in the axial direction by a gland follower and can be installed easily in new or existing equipment without any modifications. Alfred Cooper, Supervisor of Engineering, Mechanical Packing & PTFE Division 2006-02-24 http://www.johncranetoday.com/login.cfm?storyid=150 John Crane has announced a major milestone with Valero Energy Corporation's Paulsboro, N.J. refinery - a 10-year partnership providing service and support on more than 1,000 pumps and increased longevity of their sealing solutions by more than 300 percent. Bill Root, District Sales Manager 2006-02-24 http://www.johncranetoday.com/login.cfm?storyid=151 It has been said that deployment is one of the most critical elements of a successful Six Sigma* program. From top-down support and Champion Training to awareness efforts targeting all employees, the deployment process for a company is a progression from which one input leads to an output that in turn leads to another input. However, simply completing each step does not guarantee a successful Six Sigma Program. Rather, key to success is affecting the very structure and nature of the organism itself. Such a distinction clearly separates those that "walk the walk" as compared to those whom merely "talk the talk." Marilyn Fischbach, Director of Training and a Certified Master Black Belt. 2006-02-24 http://www.johncranetoday.com/login.cfm?storyid=152 The number of old pumps in operation today is staggering. Although the technology may be from yesteryear, these pumps found in the deep recesses of our factories to the far-reaching corners of our wastewater treatment plants continue to fulfill their critical mission. But, despite their longevity, many are plagued with frequent downtime and lost production. One growing trend to keep these older pumps in operation and out of extinction is the use of split seals. Doug Volden, Director of Marketing 2006-02-24 http://www.johncranetoday.com/login.cfm?storyid=141 John Crane has announced an order for a Type 28 non-contacting, dry-running gas 13.5-inch shaft diameter seal for the compressor market. The seal, which will measure 15.75 inches at its balance diameter, is expected to weigh more than 400 pounds and is being custom-designed to help a well-known North American compressor manufacturer launch a new product in order to meet market demand. Rick Page, Director of Marketing 2005-12-19 http://www.johncranetoday.com/login.cfm?storyid=142 As today's oil and gas industry continues to respond to the changing dynamics of a world economy, there is little argument that turbo machinery reliability is paramount to maximized plant operation. With oil and gas prices at historic highs, you simply cannot be shutdown because seals/compressors are not functioning to requirements. As the world's largest Dry Gas Seal supplier, John Crane has amassed industry leading expertise and success in the toughest applications. Paul Hosking, Director, Dry Gas Seals 2005-12-19 http://www.johncranetoday.com/login.cfm?storyid=143 For the second time in the last 24 months, John Crane has expanded its already state-of-the-art Morton Grove, Ill. facility by purchasing another identical Mazak Integrex e-410H machining platform for the Type 28 Group machine shop. Dramatic business growth in the past year, combined with the success of the first installation, made this the obvious choice for capacity expansion. Paul Hosking, Director, Dry Gas Seals 2005-12-19 http://www.johncranetoday.com/login.cfm?storyid=144 The pressure is rising at John Crane. As part of a long-term commitment to offering the most comprehensive testing capabilities, John Crane has upgraded their already innovative Morton Grove, Ill. testing facility. John Crane recognized the importance of meeting increased product test requirements. As such, it was crucial to expand the testing infrastructure to meet current and future industry demands. Robert Jahaske, Design Engineer 2005-12-19 http://www.johncranetoday.com/login.cfm?storyid=136 On May 5, John Crane broke ground on a new state-of-the-art seal repair, engineering, inventory and manufacturing facility in Corpus Christi, Texas. Design work began in February on the new 9,375-square-foot facility - located at the cross-roads of Southern Minerals Road and Leopard Street - and completion is expected in September of this year. Customers, community leaders and John Crane employees from around the country will be invited to an open house and tour of the facility, to be held soon after the opening. Andy Forrest 2005-08-03 http://www.johncranetoday.com/login.cfm?storyid=137 John Crane now has a state-of-the-art metrology tool designed to improve the analysis of wear characteristics of sealing faces. Phil Shefren 2005-08-03 http://www.johncranetoday.com/login.cfm?storyid=138 Within a modular cartridge design, this heavy-duty, gas-lubricated Universal Vessel Seal (7800 Series) is ideal for use in a wide variety of mixing and agitating equipment, as well as other top entry mixer applications. The Type 7800 uses modular hardware, allowing for maximum interchangeability and efficiency. This convertible format will support dry contacting, wet contacting, non-contacting or a combination of non-contacting and dry contacting seal technology without the need to change any adaptive hardware. The patented grooved rotor allows equal lift in the presence of up to 0.125-inch radial run-out, while the primary ring shape responds under pressure, further enhancing very low speed face separation and lift-off. The double cartridge use common springs, allowing for seal adjustment to axial motion. Doug Volden 2005-08-03 http://www.johncranetoday.com/login.cfm?storyid=139 While efficiency is valued in all industries, pharmaceutical manufacturing must take place in precise planned process sequences with critical time parameters. Further, all products must remain completely free from contamination from any source, particularly seal lubrication fluid. Recognizing these factors to be absolutes, a global pharmaceutical and chemical company specializing in the manufacture of bulk active drug substances sought a means to remedy leakage of seal lubrication oil. Mike Kalodimos 2005-08-03 http://www.johncranetoday.com/login.cfm?storyid=140 Available in single and double arrangements, the Type 32GL is a dry-running mixer seal designed specifically for glass-lined vessels. Ideal for top-entering mixers, agitators and reactor vessels, use of the Type 32GL eliminates damage to shafts and contamination of product, as well as reduces necessary maintenance. Mike Kalodimos 2005-08-03 http://www.johncranetoday.com/login.cfm?storyid=122 John Crane's dry-running, non-contacting cartridge seals not only ensure zero fugitive emissions from process pumps, but the seals have proven to greatly extend mean time between repair (MTBR) and reduce costs in a wide variety of hard to seal applications. Mike Kalodimos 2005-04-21 http://www.johncranetoday.com/login.cfm?storyid=124 With more than 200,000 units installed since the introduction of John Crane's Universal Cartridge Seal in 1996, it is clear that this family of seals - the Type 5600 - is the product of choice for plant-wide seal standardization. In today's streamlined and waste-reduction business mindset, the Type 5600 Seal is ideal because of its versatility and proven reliability. With interchangeable parts, the Universal Cartridge is applicable throughout a plant. The seals' modularity also allows precise customization for a wide range of applications worldwide. Mike Kraus, John Crane Market Development Manager 2005-04-21 http://www.johncranetoday.com/login.cfm?storyid=127 It is no secret that the cost of fixing pumps and related seal failure are among the highest recurring expenses in a maintenance budget. A recent study showed that one facility had repair costs of $1,600 for an ANSI overhung process pump every three to four months. At a minimum, this equates to $4,800 annually and $96,000 for the projected 20-year life of the pump. Consider the number of pumps in a typical process plant and this number grows exponentially extremely fast. The same study also found that the user of another pump reported a much higher repair bill for a single repair of $4,500; however, this pump needed repairs only every five years. This equates to $22,500 for the 20-year life, a savings of $73,500 as compared to the first pump with frequent, albeit less expensive, repairs. Jason Gondron, John Crane Manager of the Alliance Support Group 2005-04-21 http://www.johncranetoday.com/login.cfm?storyid=121 In maintenance, just as in sports, you don't know whether you are winning or losing unless someone keeps score. The "score" for many companies is the Mean Time Between Repairs (MTBR). However, unlike in a ball game, the MTBR score is subject to definitions and interpretation as other acronyms may be used to imply the same premise. Whatever the definition, using MTBR to track equipment reliability is an old idea. Although it was applied to refinery pumps in the early 1970s and described in reliability textbooks in the 1960s, it was probably used even prior to those instances. Today, "What is your MTBR" is a common question during roundtable discussions at equipment conferences. As such, is there a need for a "standard" definition of Mean Time Between Repairs? While a formal standard may seem unnecessary, it is important to note that MTBR is becoming both a benchmark and a contractual obligation. We'd like to use Pumps and Systems magazine to initiate a discussion on the definition of MTBR. Gordon S. Buck, Chief Engineer, Field Operations and Jason P. Gondron, Manager, Alliance Support Group 2005-04-14 http://www.johncranetoday.com/login.cfm?storyid=129 The best solutions are often the simplest, as evidenced by a recent scenario at a major pulp and paper mill that was brought to my attention by colleagues at John Crane. John Crane 2005-04-07 http://www.johncranetoday.com/login.cfm?storyid=125 Sealol was developed in 1957 to solve critical and demanding applications for NASA. The technology was later extended to the process industry because of its outstanding performance in critical applications For more than six decades, Sealol brand metal bellows seals have been recognized for their excellent performance capabilities and sealing reliability integrity in a wide range of industrial rotary shaft applications. With three basic seal designs to choose from - elastomer bellows, metal bellows and PTFE bellows - the differences are significant and establish their unique performance capabilities in terms of pressure, temperature and fluid application range. John Crane 2005-03-21 http://www.johncranetoday.com/login.cfm?storyid=123 John Crane recently reached a major milestone - production of the 50,000th Type EZ-1 cartridge-mounted metal bellows seal. Meredith Westner, Quality Assurance Manager and leader of the Cell for the Type EZ-1, credits this milestone to the seal's universal cartridge design and interchangeable O-rings. This versatility offers customers huge savings in inventory and maintenance hassle, allowing plant managers to easily convert a large number of applications to the Type EZ-1, she said. Paul Richards, John Crane Product Manager for the Type EZ-1 2005-03-21 http://www.johncranetoday.com/login.cfm?storyid=120 Travel back to 1979, when Jimmy Carter was President, the Bee Gees' Saturday Night Fever topped the record charts, and the Pittsburgh Steelers beat the Dallas Cowboys in the Super Bowl. Three days after Christmas, a pipeline coordinator at a major oil and gas exploration company found himself replacing a seal on a pipeline pump in New Jersey. He remembers wishing to himself on that bitterly cold day that the new seal - a John Crane Type 8B1 - would last longer than the previous one did - a mere two years. Frank Jasionowicz,John Crane Sales Representative 2005-01-14 http://www.johncranetoday.com/login.cfm?storyid=114 A recent analysis, performed by John Crane on a variety of sealing products for pumps and rotating equipment, confirmed that split seals offer significant, measurable advantages for process industries - specifically improved reliability, increased uptime and reduced maintenance costs. Tom Evans, Marketing Manager 2005-01-06 http://www.johncranetoday.com/login.cfm?storyid=119 Even if they LOOK and FIT the same, not all seals PERFORM the same.Seals manufactured with poor quality materials may cost less initially, but will likely result in additional cost, lost time and warranty hassles. Reduce your exposure and protect your bottom line with the same proven seal technology OEMs have trusted for 80 years. As the leader in serving the needs of the water and wastewater industry, John Crane offers.. John Crane 2005-01-06 http://www.johncranetoday.com/login.cfm?storyid=117 Although a Washington state pulp and paper mill had relied on traditional braided packing for nearly 75 years, the company sought a means to reduce high repair and maintenance costs associated with this sealing method. A tight fit was difficult to achieve and maintain, resulting in leakage of water and paper stock as well as a messy environment and troublesome clean-up. Tom Evans, Marketing Manager 2005-01-06 http://www.johncranetoday.com/login.cfm?storyid=113 Although John Crane has always provided customer support and service on a genuinely GLOBAL scale, an expanded network of service facilities offering rapid and easy access to state-of-the-art gas seal testing and refurbishment also ensures 24/7 service on a LOCAL level. While many providers are downsizing, consolidating and even outsourcing, John Crane has responded to customers' needs by increasing the number of service centers and mobile support engineers around the globe. Whether you require service or inventory in Norway, Brazil, Singapore, Russia, Saudi Arabia, Iran or beyond, John Crane is just around the corner. John Crane 2004-10-01 http://www.johncranetoday.com/login.cfm?storyid=115 Through alliance programs and more than 100 dedicated managers, engineers, and technicians working at customer facilities around the world, John Crane is now servicing more than 100,000 pumps. Although this quantity is impressive, what is even more important is the cost benefit of this team approach. According to Tim Reece, John Crane Manager for Strategic Alliance Development, the alliance programs lower overall costs and improve productivity by providing engineering and technical expertise on-site. John Crane 2004-10-01 http://www.johncranetoday.com/login.cfm?storyid=116 John Crane recently committed significant resources to its already state-of-the-art Morton Grove facility by integrating a Mazak Milling Machining Center Integrex e-410H into the Type 28 Group. According to Carter McWilliams, John Crane Project Engineer, the Mazak enables multitasking and more efficient processes by combining four separate machining functions - rough turn, finish turn, and two milling operations - into one. The high-performance multitasking Mazak is capable of serving as a machining center and turning center combined, allowing the Type 28 product line to be turned and milled in one program. Further, the ability to quickly and easily go from a single set-up to completed machined parts will minimize inventory for John Crane. John Crane 2004-10-01 http://www.johncranetoday.com/login.cfm?storyid=118 With excessive air-entrained stock in the headbox at Weyerhaeuser's Rothschild, Wis. paper mill, maintenance engineers suspected air leakage through the packing in the fan pump. Installed in 1969, this continuously operating split-case fan pump serves as one of the most critical pumps in the mill and fan pump downtime for major maintenance resulted in as much as 16 hours of lost production. Tom Evans, Marketing Manager 2004-09-01 http://www.johncranetoday.com/login.cfm?storyid=85 In today's cost-conscious and just-in-time production environment, finding the root cause of a seal failure is often replaced with a quick fix or band-aid. These challenges occur even in the newest of facilities, such as the Quad County Corn Processors three-year-old ethanol plant in Galva, Iowa. With a production rate of more than 22 million gallons of ethanol product each year, extensive seal failures were taking a toll on operations. Mike Kraus, John Crane Inc. Market Manager 2004-07-02 http://www.johncranetoday.com/login.cfm?storyid=112 Sometimes the best solutions go beyond leading-edge technology; rather, the answer is a result of a fast-track team approach and superior service. One such example is John Crane's recent experience teaming with Concentric Engineering and Fleetguard Inc. to solve a water pump seal failure on a Cummins' ISL Pegasus mid-range engine used in bus applications. John Crane 2004-06-29 http://www.johncranetoday.com/login.cfm?storyid=111 Time is running out to secure your space at the popular John Crane Academy "Get Connected to Power Generation Sealing Technology Advancements" seminar. The day-long session — to be held Sept. 21 in Los Angeles and Nov. 16 in Philadelphia — is designed for maintenance mechanics and supervisors, plant and reliability engineers, EPC firm personnel, contractors, rotating equipment OEMs and others involved with the selection, installation, support, maintenance and repair of seals and related support systems in power plants. John Crane 2004-06-29 http://www.johncranetoday.com/login.cfm?storyid=110 Although the marketplace is filled with a plethora of buzzwords surrounding just-in-time delivery and logistical strategy, there are still limitations in terms of actual service channels. As such, John Crane has launched John Crane Express - a program designed to better serve those in high volume industries that require a large quantity of mechanical seals. The program, accessible by entering a unique name and password at www.johncraneexpress.com, allows you to manage your orders and needs at any time, from any computer terminal via the Internet. John Crane 2004-06-23 http://www.johncranetoday.com/login.cfm?storyid=109 Much debate surrounds the role of the water pump seal in improving engine coolant system performance. Yet, those that attended the March 8 SAE 2004 World Congress and Exposition session entitled "Improving Engine Coolant System Performance with the Science of Sealing Technology, Part II," had the opportunity to learn first-hand about new research detailing the impact of coolant fluid on system components and reliability. John Crane 2004-06-23 http://www.johncranetoday.com/login.cfm?storyid=86 Building on a modular concept that allows application-specific arrangements incorporating interchangeable elastomer bellows, O-ring and metal bellows seal heads, John Crane's 5600 Universal Cartridge Series is ideal for the ethanol industry. Mike Kraus, John Crane Inc. Market Manager 2004-06-15 http://www.johncranetoday.com/login.cfm?storyid=134 There are a variety of mechanical seal methods used today depending upon the nature of the individual application. The single mechanical seal is first choice to consider because its simplicity on set up and lower initial costs. When using a single mechanical seal, the lubricant between the seal faces is the process fluid itself. In the case of sealing Ammonia, it is important to remember that this process fluid is really a liquefied gas. It is under pressure so as to be in a liquid phase... John Crane 2004-05-17 http://www.johncranetoday.com/login.cfm?storyid=135 A quench is a low-pressure blanket or flow over the atmospheric side of a mechanical seal. Often referred to as API Plan 62, it can significantly extend the Mean Time Between Pump Repair by providing an improved environment for the mechanical seal. Services that contain solids or form solids that may build up on the atmospheric side of the seal can benefit from quenching. If the solids are allowed to build up unchecked, they will cause the seal to lose its flexibility, degrading the face film and lead to permanent damage of the seal faces that can be construed as seal failure. John E. Finley, Sales Engineer & Tom Borrino, Regional Engineer 2004-05-17 http://www.johncranetoday.com/login.cfm?storyid=133 In most seal designs, the heat generated at the faces enters the fluid surrounding the seal. This often results in an increase in temperature for the fluid unless it is cooled or continuously replaced or the fluid may become too hot for reliable seal performance. For this reason, most seals operate with continuous replacement of the surrounding fluid - a process known as "seal flush." John E. Finley, Sales Engineer 2004-04-29 http://www.johncranetoday.com/login.cfm?storyid=130 Every seal application should be reviewed in terms of the optimal means of minimizing the effects of solids. Flushing, quenching, integrating hard face materials and reducing the forces that close the seal faces are just some of proven tools used to combat abrasives. However, the first step in preventing a problem is evaluating the seal face film. Liquid face films are generally on the order of 10 to 20 micro-inches thick and heat generation at the faces is in part a function of film thickness. As the film becomes thinner, heat generation increases and the faces distort and become wavy where they should be flat. This waviness creates lift and re-establishes the normal face film thickness. John E. Finley, Sales Engineer 2004-04-27 http://www.johncranetoday.com/login.cfm?storyid=131 Water used in the diverse industries served by John Crane varies in source from river water to a wide variety of treated waters. Regardless of the source, impurities present in water used by power, water treatment, wastewater and ethanol plants, as well as other industries, cause problems by forming deposits on components and equipment surfaces, thus impairing heat transfer, fluid flow and overall process efficiency. These deposits also contribute to corrosion of metal surfaces. John E. Finley, Sales Engineer 2004-04-27 http://www.johncranetoday.com/login.cfm?storyid=132 Caustic is a term applied to chemicals used to neutralize any acids or other by-product remaining in the process. The most common of these chemicals are caustic soda, otherwise know as sodium hydroxide (NaOH), and potassium hydroxide (KOH). Depending upon temperature and concentration, both can be extremely corrosive. Experience has shown that the best choice for sealing this highly corrosive application is a John Crane Type 5610Q or a Type 5611Q cartridge seal. John E. Finley, Sales Engineer 2004-04-27 http://www.johncranetoday.com/login.cfm?storyid=75 Building on a successful March seminar, John Crane Academy will once again offer the popular "Get Connected to Power Generation Sealing Technology Advancements" seminar on June 15. To be held in Atlanta, the program is designed for maintenance mechanics and supervisors, plant and reliability engineers, EPC firm personnel, contractors, rotating equipment OEMs, and others involved with the selection, installation, support, maintenance and repair of seals and related support systems in power plants. John Crane 2004-03-30 http://www.johncranetoday.com/login.cfm?storyid=82 Joe Delrahim, John Crane Marketing Manager/Gas Seal Specialist, will serve as a featured speaker at the XVI International Gas Convention, to be held May 25 - 27 in Caracas, Venezuela. Sponsored by the Venezuelan Gas Processors Association (AVPG), Delrahim will present a session detailing key factors necessary for achieving reliable and successful operation of dry gas seal technology. John Crane 2004-03-30 http://www.johncranetoday.com/login.cfm?storyid=83 John Crane is pleased to announce its recognition as a Top Supplier from ITT/Goulds Pumps (www.gouldspumps.com), one of the fluid companies of ITT Industries. With more than a million process pumps installed worldwide and a 150-year history, Goulds Pumps is the leading global pump supplier in a variety of industrial markets. A long-time supplier to Goulds Pumps, this is the second time John Crane has received this award. John Crane 2004-03-30 http://www.johncranetoday.com/login.cfm?storyid=81 There is little argument that the handling of chemicals, especially volatile ethylene and propylene oxide, is a delicate procedure that requires precise skill and extreme attention to detail. Although both are hazardous to human health, the presence of an oxygen molecule results in the overriding concern of ignition and explosion. As such, controlling product release to the atmosphere, even a minimal amount, is paramount. John Crane 2004-03-30 http://www.johncranetoday.com/login.cfm?storyid=84 To meet the needs of those specifying the latest in flexible, resilient, and reliable packing solutions, John Crane has developed literature on RitePak Packings. The 12-page brochure highlights available off-the-shelf packing solutions for general, abrasive, chemical, food, and high temperature chemical service applications. 2004-03-30 http://www.johncranetoday.com/login.cfm?storyid=77 A large mechanical seal, still in operation more than 13 years after installation, gives new meaning to the axiom, "If it ain't broke, don't fix it." According to Colin Munro, John Crane sales representative, a John Crane Type 37FSB mechanical seal, installed in 1991 at a large water pollution control plant located at the southern tip of San Francisco Bay, Calif., is still in operation. John Crane 2004-02-20 http://www.johncranetoday.com/login.cfm?storyid=76 When a compressor seal fails in an oil and gas facility, such as an offshore platform, the maintenance specialist must get the compressor back into operation as quickly as possible. But it is also true that, where possible, the maintenance person needs to determine the root cause of the failure. More often than not, seals fail because of their environment, including gas composition, and their interaction with other components. Replacement without understanding a failure's cause can cause another failure. Joe Delrahim, Marketing Manager, John Crane 2004-02-19 http://www.johncranetoday.com/login.cfm?storyid=79 Although originally developed for the pulp and paper industry, John Crane's Type 5870 flushless seal has already been proven in a variety of process industries, water and wastewater plants, as well as food and beverage facilities. Now, the factory-preassembled, single cartridge seal is making inroads and providing great value to members of the ethanol industry. Tom Evans, John Crane Inc. Market 2004-01-01 http://www.johncranetoday.com/login.cfm?storyid=73 John Crane is honored to announce its recognition as a Top Supplier Performer for 2002 from ITT/Goulds Pumps. A supplier for decades to Goulds Pumps, one of the fluid companies of ITT Industries, this is the first time John Crane has received this award. With more than a million process pumps installed worldwide and a 150-year history, Goulds Pumps is the leading global pump supplier in a variety of industrial markets. John Crane 2003-12-02 http://www.johncranetoday.com/login.cfm?storyid=72 Metal bellows sealing technology continues to grow as a solution for effectively preventing fugitive emissions in difficult chemical applications. Two seal designs in particular -- a dry-running metal bellows secondary containment seal and a non-contacting metal bellows seal -- are especially advantageous for pump users, though each for different reasons. Jesse J. Fordyce, Market Manager 2003-12-02 http://www.johncranetoday.com/login.cfm?storyid=74 In the early 1980;s, Flexibox Limited, a well known manufacturer of mechanical seals in England (now a part of John Crane), developed a dry-running outer seal that replaced the conventional wet seal used in "tandem" arrangements. That design, the SBOP, began the revolution that led to the advanced dry-running containment seals of today. Today, in addition to the SBOP, John Crane offers a full line of products which include the 48SC, 5620D and Sealol ECS as contacting designs as well as the 28LD and 28SC non-contacting designs. Yet despite the growth in products, there is still some ambiguity regarding the guidelines for using containment seals. Gordon S. Buck 2003-12-02 http://www.johncranetoday.com/login.cfm?storyid=69 If converting meters to feet or deciliters to drums conjures flashbacks of pop quizzes in your junior high school math class, simply use the new Conversion Calculator found on John Crane Today.. John Crane 2003-10-08 http://www.johncranetoday.com/login.cfm?storyid=71 Streamlining operations has certainly hit the agenda of manufacturing and industrial segments all over the globe. However, though companies fully recognize the importance of centralizing such functions as design or their billing operations, too often components - such as mechanical seals -- are overlooked. And when such programs represent numerous product vendors and processes, the result is often increased maintenance, intense coordination with vendors and higher costs. John Crane 2003-10-08 http://www.johncranetoday.com/login.cfm?storyid=67 MultiLube is a compact, self-contained system that provides lubrication to a local area. Its modular, centralized design makes it simple to install, easy to operate, and creates a flexible, highly efficient lubrication solution. The result is an optimum lubrication system, which helps reduce both energy and lubricant consumption. The MultiLube system is compatible with most pumpable oils and greases and can lubricate all types of gears, chains, bearings and moving components. John Crane 2003-08-27 http://www.johncranetoday.com/login.cfm?storyid=68 Some of the most useful tips and insights are found by reviewing your peer's problems and challenges. As such, John Crane Today is launching Notes from the Field. Moderated by the renowned Gordon S. Buck, John Crane's Chief Engineer - Field Operations, Notes from the Field is your forum for dispelling myths, solving problems and learning more about today's engineered sealing solutions. John Crane 2003-08-09 http://www.johncranetoday.com/login.cfm?storyid=70 It is important to realize that API 682 is a users standard; it was written by and for the end-users of mechanical seals because these users wanted to force changes in the industry. Radical changes were expected in both the seal industry and its customers with the first publication of the standard in 1994. The new version, published in 2002, was written around a limited set of seal types, arrangements and materials that were favored by the end-users of mechanical seals. In addition, these new seals were required to be proven through a series of rigidly prescribed tests. Gordon S. Buck, Chief Engineer - Field Operations 2003-08-08 http://www.johncranetoday.com/login.cfm?storyid=66 In April 1963, engineers at the Kenosha Water Utility (located on Lake Michigan in Wisconsin) installed two Delaval Type 100 M vertical pumps fitted with John Crane Type 1 mechanical seals on the facility's north and south backwash pumps. This spring, plant operators discover a leak in the north backwash pump caused by a clogged flush line -- ending a 40-year lifespan of John Crane's fist patented mechanical seal - a service that endured an estimated two billion gallons of clean water. What is even more remarkable is that plant personnel inspected the sister seal on the south backwash pump, also installed in 1963, and found it to be in good condition -- 40 years on the job and still running as it did when first installed. Even though longevity has always been a hallmark of John Crane's mechanical seals, 40 years of service is an aberration. Mike Kraus 2003-07-25 http://www.johncranetoday.com/login.cfm?storyid=65 A one-day lifespan on a process pump seal has drastic effects. Just ask Maintenance Manager Russell Konwinski at the Abengoa Bioenergy ethanol fuel plant in York, Nebraska. While double seals are typically the recommended solution, the time and expense associated with the installation of a pressurized seal support system and the potential to dilute the process fluid with barrier water escaping the seal, were real concerns. Fortunately, John Crane had already recognized the need for a flushless single cartridge seal and launched the Type 5870. The seal has not only saved dollars in terms of decreased maintenance and downtime, but has also reduced the product and maintenance cost associated with replacing new seals. Tom Evans, Marketing Manager 2003-06-05 http://www.johncranetoday.com/login.cfm?storyid=62 Over the past several years, the Louisville Plant of Rohm & Haas has reduced its average cost per installed seal by 42% and nearly doubled the mean time between seal failure (MTBSF). That success is the result of a Seal Alliance Initiative that included John Crane as an Alliance partner. This article details the failure documentation and analysis processes, improvements in seal warehousing and management, and the benefits of the Seal Alliance Initiative. Rohm & Haas Reliability Revolution Newsletter 2003-05-08 http://www.johncranetoday.com/login.cfm?storyid=64 Many factors can affect seal performance. A partial list might include seal design, seal load, lubrication conditions, the fluid being sealed, shaft size, shaft speed, pressure and temperature of the pumped fluid. The selection of materials applied in the seal design and, in particular, the material of the contacting seal faces plays a major role in the overall performance of any seal. Sealide-C (tm) is the latest development in engineered seal face material technology. It is a state-of-the-art sintered silicon carbide composite specifically designed to provide longer service life in virtually all pump and compressor applications. Sealide-C has been shown to provide longer life, very low leakage and trouble-free service. Based on extensive laboratory testing and many successful hours of endurance testing at John Crane, Sealide-C is being applied today to the the toughest of seal applications. John Crane 2003-04-01 http://www.johncranetoday.com/login.cfm?storyid=63 Ask a hundred automotive engineers which engine component they think is the most important, and not many will say it's the water pump seal. Maybe they should think twice. Automotive engines require highly reliable cooling systems for optimum performance, and the water pump seal is the most critical component within the cooling system. Jim Netzel, Senior Staff Engineer, John Crane 2003-02-07 http://www.johncranetoday.com/login.cfm?storyid=61 John Crane has developed a seal support system known as a Gas Conditioning Unit (GCU) that will advance the performance of dry gas seals by solving several critical gas supply issues...
