An Emperor Without Clothes?


emember the story of “The Emperor’s New Clothes?” Once upon a time, a vain Emperor engaged the services of two swindlers masquerading as weavers, who promised to make him a suit from magic cloth. Amazingly, the new clothes would be visible only to persons competent and fit for their jobs. Thus, when sent to check on the progress of the project, the Emperor’s representatives reported that the non-existent suit was magnificent! Had they admitted there were no clothes, they would have been labeled incompetent or unfit! Checking for himself, the Emperor also proclaimed the new clothes to be magnificent, lest he, too, be deemed incompetent or unfit for his position. Only when he ostensibly donned his magic finery and paraded in public did a child— with no position to protect—clarify what was painfully obvious: that the Emperor was naked. Still, the Emperor continued to proudly march on. This fairy tale is a metaphor, of course. For our purposes, it can be used to describe a management that chooses to believe it has an effective program in place, and those working in the program who see the reality (or pretense), but choose not to be contrary for fear of reprisal. Visiting a self-proclaimed “World-Class” facility recently, I was surprised to hear managers claim they had simultaneously implemented their maintenance program based on Lean Maintenance, Overall Equipment Effectiveness (OEE), Reliability Centered Maintenance (RCM), Total Productive Maintenance (TPM) and Preventive/Predictive Maintenance (PM/PdM). This “combined approach,” they avowed, had led to huge gains in equipment uptime and reliability—despite an asset management system that wasn’t set up to report Mean Time Between Failure or Availability. Apparently, management felt its level of investment in the system had to be producing the desired effect! Unfortunately, in examining the plant’s lubrication-management program, I found the typical PM job task “Lubricate as necessary” still in use,


with the program’s success relying on a recently created “oiler” position. The new “oiler” had been chosen primarily because of seniority. Lacking any experience with lubricants or their application, he believed that the purchase of new grease guns constituted a lubrication-management program!

If your program is in disarray and your ‘Emperor’ has no clothes, let this magazine be your voice. Many of the maintainers with whom I spoke off the record considered the new maintenance approach to be “smoke and mirrors”— and confusing and detrimental to asset health. They further believed there was no real program in place, but felt unable in these economic times to criticize the situation, albeit constructively, in front of management. Not surprisingly, maintainers had not been part of the programimplementation team. Having visited hundreds of facilities in similar denial over the years, I’ve continued to be stunned (and saddened) by the type of short-sighted approach that views the creation of an “oiler” position and purchase of new grease guns as state-of-the-art lubrication management. If your lubrication efforts are in this type of disarray, and your Emperor has no clothes, let this magazine be your voice. Leverage the tips, strategies and solutions you find in our pages to show management the real meaning of a “Best-Practice Lubrication Program.” Good luck! And what about the “World-Class” operations referred to earlier? As a consultant, I was the “child” who pointed out the absence of “clothes.” Alas, to date at this plant, the Emperor has chosen to proudly (and nakedly) march on. LMT | 5


Make Energy An Asset, Not An Afterthought


n an April 2010 survey of leading businesses entitled “From Shop Floor to Top Floor: Best Business Practices in Energy Efficiency,” the PEW Center on Global Climate Change describes a shift in how companies such as Dow, IBM and Toyota approach energy. The authors’ conclusions? Setting ambitious long-term energy-saving goals saves money, avoids greenhouse-gas emissions and improves employee morale. Ultimately, survey participants have boosted their bottom lines by approaching energy as a core asset to be managed, rather than as an expensive afterthought. Traditionally, however, efficiency opportunities have been addressed through incremental improvements. While such savings are notable, managing efficiency on an organization-wide basis greatly expands the potential. In this new paradigm where energy is viewed as an “asset,” more comprehensive changes are pursued. This paradigm shift can be viewed in the context of how your facility approaches energyintensive equipment, such as motors. Imagine the effects on your bottom line from upgrading to premium-efficiency motors one by one, versus an approach based on a comprehensive motormanagement plan. For example, a proactive motor-management plan would involve maintaining an inventory of all motors and ensuring that energy was included in the analysis of when and how they are to be repaired or replaced. Incorporating the motor-management plan as a business strategy assures that all personnel contribute and adhere to it. What’s the impact to your bottom line? It’s likely to be a very large number: Multiply the savings you would achieve by upgrading one motor by the number of motors in your facility—the U.S. Department of Energy has estimated this could be $900/year for a 75 hp motor—and add to that the avoided productivity losses associated with being unprepared when critical motors fail.



Another important finding of the PEW study was that at leading companies, senior management supports managing energy as an asset. This approach permeates all levels of the companies’ organizational charts. As a result, the benefits extend beyond the bottom line to include improved productivity by stimulating technical and process innovations, such as reductions in water use, materials waste, labor costs and production downtime. Where to start? If the successes achieved by companies in the PEW Center survey seem to be beyond your company’s budget, resources or manpower, you may want to try something simple that can still have plenty of impact: Start managing your energy asset by managing your motors. If your facility is like most others, motordriven systems consume a large portion of your energy use. The sponsors of the Motor Decisions MatterSM Campaign have developed a suite of resources to help you and your team be more effective in managing those systems and, in turn, your energy asset.

Keeping Motors And Gearboxes In Tip-Top Shape Want to insure against the failure of these critical systems? Protect them with the correct lube prescriptions and protocols. Ken Bannister Contributing Editor


oes your computerized maintenance management system (CMMS) currently classify your driver/driven motor gearbox combination units as two separate assets—motor and gearbox? Or does it view them as a single combined asset, or as a sub-component of a piece of proprietary equipment? Does your lubrication PM work instruction for both motor and gearbox spell out the lubricant type and amount required, or is the statement to “Lubricate as Necessary” the only guidance you have? In either scenario, if you’re not treating your motors and gearboxes as separate entities, each requiring its own detailed lubrication regimen, you have already ventured down the slippery slope to premature failure.




Assuring motor and gearbox reliability calls for a two-pronged plan of attack: 1. Good alignment practice and, more importantly, 2. Effective lubrication practice. The driver/driven combination of a motor/gearbox is an assembly of two specific entities—one electro-mechanical (an always-serialized motor); the other purely mechanical (an often-serialized gearbox)—that must be treated individually when assessing their lubrication needs. When treated with care and respect, these entities can be expected to outlive their driven components. This short overview focuses on the major symptoms of poor lubrication practices and some straightforward maintenance strategies for making your lubrication program more effective in protecting the health and well-being of your hardworking motors and gearboxes. Motor lubrication In simple terms, motors are electro-mechanical devices that turn electrical energy into mechanical energy. The motor magnets and windings are wound on to a shaft simply supported by two or more bearings at either end of the motor frame. These bearings—usually rolling-element types such as ball, roller or needle bearings—are the only lubrication points on

a motor. They are almost always grease-lubricated. Most fractional- and small-horsepower motors make no provision for bearing lubrication (no grease nipples provided). A unit like this is typically designed to utilize the original grease lubricant filled within its sealed bearing cavity to provide lubrication throughout its service life. With smaller motors, loads are usually light; the lubricant rarely needs replenishment if a unit is balanced and aligned correctly. Depending on the motor design and manufacturer, external grease fittings usually start to appear on motors rated 20 hp and above—and always are evident on motors 50 hp and above. When motors become more powerful and heavier, more static and driven load is placed on the bearing points, thus requiring grease replenishment on a more frequent basis. If a motor is to operate at peak efficiency, its bearing cavities (the available space between the balls, raceways, cage and seals) should only be filled to 30-50% of capacity with lubricant. Without the air space this affords, the grease would not be able to penetrate and work within the bearing contact surfaces. Instead, a condition known as “churning” (in which the fluid friction of the grease tries to retard the easy moving action of the bearing) would be set up. In order to overcome this internal resistance, a motor must draw more power and the resulting frictional heat breaks down the lubricant properties, significantly reducing its working life. Motors “designed” to be greased will have a grease nipple located on top of the motor at each end. Located 180 degrees from the nipples is a capped drain plug that’s designed to be unscrewed and allow excessive grease to channel through

Diligence must also be exercised in performing the lubricating procedure to ensure no dirt is introduced inadvertently into the bearing cavity due to an unclean grease gun tip or grease nipple. To ensure that motors don’t run hotter than they are designed to run, and windings are never used as grease reservoirs, heed the following tips: Motor lubrication tips… n Ensure all maintainers are fully trained in how to correctly lubricate a motor. n Remove grease nipples from all fractional- and lowerhorsepower motors (20 hp and less) and run to fail. n Identify the correct grease to use on the PM work order and with a tag affixed to each motor. n Identify the correct grease requirement on the PM work order by number of shots, after ensuring all grease guns in the plant have identical output per shot.

the bearing and out of the motor during lubrication. If this drain is kept capped during the greasing process, excessive lubricant will channel directly through the bearings past the seals and into the motor windings—where it will eventually “cook” as the motor spins. Unfortunately, motors with grease points suffer a disproportionate amount of premature failures caused by over-lubrication, mixing of lubricants and contaminant inclusion. Over-lubrication, by far the biggest sin, results from the mistaken belief that if a little lubrication is good, “a lot of lubrication is a lot better!” Motors are designed with a specific grease lubricant in mind—usually one with dielectric properties so as not to ground out the motor if the grease mistakenly enters the windings. Maintenance teams must exercise great diligence in ensuring the correct grease is always used and not mixed with another type, since not all greases are compatible. Mixing incompatible lubricants is a sure way to greatly reduce a bearing’s (and a motor’s) life.

n Investigate the use of automated single-point lubricators for roof fans and remote locations. Gearbox lubrication Gearboxes are, essentially, simple, self-contained mechanical devices that allow power to be transmitted from an input shaft to an output shaft at different speeds through the meshing of different-sized gear sets held on each shaft. The gears and shafts are supported on bearings contained within a sealed “box” that also serves as a reservoir for the lubricating oil. Gearbox dimensions can range from palm-size to room size and, with few exceptions, are oil-lubricated. Depending on the style and size, gearboxes employ a number of methods to move the lubricant over the gears and bearings, the most popular being: n Splash lubrication…This is the most common gearbox lubrication method. It involves filling the reservoir partway with lubricating oil to ensure partial coverage of all the lower mating gears. At speed, these gears use surface tension on their teeth to “pick up” lubricant and transfer to other gears and bearings through meshing and by “flinging and splashing” the lubricant in all directions within the sealed reservoir. Continued on page 12

If you’re not treating your motors and gearboxes as separate entities, you’ve already ventured down the slippery slope to premature failure.

n Pressure or force-fed lubrication…This lubrication method is typically found on mid- to large-size gearbox assemblies. It employs a gear-driven pump, usually located inside the gearbox, to work in conjunction with the “splash” method. The pump picks up lubricant through a pick-up filter screen and pumps it at pressure through an internal piped delivery system to bearings and gears that would be difficult to service with traditional “splash” lubrication. A replaceable or washable filter and pressurerelief valve are employed within the system to further protect the gearbox wear surfaces from harmful particles.

n Hot gearbox…This situation frequently results from excessive dirt on the outside of a gearbox, which then creates a thermal blanket that wants to “cook” the oil inside. Incorrect lubricant viscosity, caused by the mixing of lubricants or wrong lubricant choice, will cause excessive heat through fluid friction (too thick), or boundary metal-to-metal contact friction (too thin), both of which cause the oil to overheat and prematurely fail. Too little lubricant in the reservoir results in boundary-layer friction. Conversely, overfilling of the reservoir will create a churning and foaming of the lubricant

n Mist or atomized lubrication…This method of lubrication is usually reserved for the largest of gearboxes. It involves a vane pump that picks up lubricant from the reservoir and “flings” it at a plate, causing it to atomize into a fog. This fog then saturates all the mechanical components within the sealed gearbox.

Both conditions will significantly reduce the life of the lubricant and, correspondingly, the service life of the gearbox. They both require more power to be drawn from a motor—which wastes precious energy. To get the longest and most productive service life from your gearboxes, keep the following lubrication tips in mind:

In all cases, the lubricant provides surface-wear protection, corrosion protection of metal surfaces and cooling of gearbox internals. No wonder that the correct choice of lubricant is essential to its longevity. Typically, gearbox lubrication problems manifest themselves in two main ways:

Gearbox lubrication tips… n Ensure all maintainers are fully trained in how to correctly perform gearbox lubrication.

n Reservoir sludge…This malady often shows up after the mixing of incompatible lubricants, during oil changes or top-up procedures. It can cause additive packages to deplete faster than designed, resulting in a drastic viscosity change. Water introduced through a cleaning process or condensation within gearboxes subjected to varying heat cycles can mix with the detergents and soaps in the lubricant, creating a thick soap sludge. Oxidation of a lubricant that has been subjected to extended use, overheating or contamination can cause the lubricant to thicken into a damaging sludge that is difficult to pump around the gearbox.

When treated with care and respect, motors and gearboxes can be expected to outlive their driven components. SICK SITUATION: Although this overfilled gearbox does have a maximum-level lubricant indicator, it does not have a minimumlevel indicator. (Photo courtesy of EngTech Industries, Inc.)




Shaft Alignment

& Geometric Measurement

HEALTHY SITUATION: This small-hp motor/gearbox combination unit has a sight gauge (to right) that clearly indicates high/low gearbox oil levels. (Photo courtesy EngTech Industries, Inc.)

n Attach a label to the reservoir, clearly indicating the correct lubricant manufacturer, product name and viscosity to be used. Clearly indicate the same information on the PM work order—without exception! n If the reservoir is regularly cleaned with water, ensure the fill cap and breathers (if applicable) are waterproof and in place at all times, or position a water deflection shield over the reservoir.

Vibration Analysis

& Balancing

n Always ensure the correct lubricant is being used for the application’s ambient temperatures. When changing lubricants, make sure the cap and breathers are always reinstalled, and that the lubricant is transferred using dedicated clean equipment. n Use oil analysis to determine when the oil is starting to “break down” its additive package and in need of change. n Make gearbox cleanliness an essential part of your PM program. n Consult the gearbox specification manual, or with a lubricant expert, to ensure your lubricant viscosity choice is correct. n Make sure the gearbox reservoir incorporates a visible sight gauge that is clearly marked with the upper and lower reservoir limit lines—much like a dipstick. n Consider the use of synthetic lubricants for your gearboxes. They will run cooler than mineral-based oils. (The use of synthetic lubricants in gearboxes has been shown to reduce energy consumption by as much as 4%.)

PROCESS IMPROVEMENTS This is a follow-up to an NSK-supplied article on three other reasons for bearing failure— creep, flaking and smearing—that ran in the September/October 2009 issue of LMT.


3 Reasons For Premature Bearing Failure (And How To Avoid Them) Listening to what your failed bearings are telling you today can help minimize problems tomorrow.


ou’ve heard it before: Every failed bearing tells a story— one that can help you identify machinery problems, maintenance issues, bearing-selection errors, installation problems and more. Are you listening?

Premature bearing failure is costly, both in terms of component replacement and unscheduled downtime. Fortunately, many types of bearing damage can be spotted, assessed and addressed—before failure occurs. The ability to proactively identify issues that affect bearing performance and wear is key to ensuring that your facility stays up and running as required.

Special To LMT From NSK

Fig. 1. What seizure looks like




Understanding types of bearing damage, along with their causes and solutions, can help boost reliability and cut maintenance. A previous article (“3 Reasons for Premature Bearing Failure,” pgs. 14-16, LMT, September/October 2009) discussed creep, flaking and smearing. In this follow-up, the focus is on three more killers: seizure, cage damage and fretting. #1. Seizure When sudden overheating occurs during rotation, bearings can become discolored. The raceway rings, rolling elements and cage begin to soften, melting and becoming deformed as damage accumulates. WHAT TO LOOK FOR: Discolored bearing elements and melting of the roller surface, resulting in adhesion of worn particles from the cage

■ Large moment load

Possible causes…

■ Shock or large vibration

■ Poor lubrication

■ Excessive rotation speed, sudden acceleration and deceleration

■ Excessive load

■ Poor lubrication

■ Excessive rotational speed

■ Rise in temperature

■ Excessively small internal clearance


■ Entry of water and debris

■ Review mounting method.

■ Poor precision of shaft and housing, excessive shaft bending

■ Reduce vibration.


■ Re-select cage type, lubrication method and lubricant.

■ Review lubricant and lubrication method.

■ Assess temperature, rotation and load conditions.

■ Investigate suitability of bearing type.

#3. Fretting Fretting is the specific type of wear that occurs as a result of repeated sliding between two surfaces. It occurs at the fitting surface and the contact area between the raceway ring and rolling elements. WHAT TO LOOK FOR: Reddish-brown or black worn particles

■ Study the preload, bearing clearance and fitting. ■ Improve the sealing mechanism and mounting method. ■ Check precision of the shaft and housing.

Fig. 2. What cage damage looks like

#2. Cage damage Several types of cage damage can affect the life of a bearing. These include fracture of the cage pillar, deformation of the side face and wear of pocket or guide surfaces. WHAT TO LOOK FOR: Fractured cage Possible causes… ■ Poor mounting or bearing misalignment ■ Poor handling

Possible causes (of fretting)… ■ Poor lubrication ■ Vibration with a small amplitude ■ Insufficient interference Solutions… ■ Use appropriate lubrication for bearing type and application. ■ Apply a preload. ■ Check the interference fit. ■ Apply a film of lubricant to the fitting surface. Remember this When a bearing is damaged, it doesn’t affect just a single piece of equipment: It can cause entire operations to grind to a halt. No facility or machinery is immune to unexpected bearing failure. When this type of failure occurs, the right response is crucial. While your immediate concern may be to install a replacement component, a proper assessment of the bearing damage should follow in order to pinpoint its actual cause. Failure to find the root cause of the problem increases the risk of unnecessary repeated failures, downtime and expense. Proactive bearing-failure analysis prolongs bearing life, improves productivity and reduces maintenance costs. Take the time to identify and resolve issues around bearing selection, mounting, lubrication and application. When additional technical expertise is needed, ask an industrial specialist from the manufacturer to perform a failure analysis and recommend the most appropriate solution.

UM BIG MONEY TALKS William C. Livoti

Today’s Entitlement / Tomorrow’s Privilege


he North American electricity system is one of the great engineering achievements of the past 100 years. This infrastructure represents more than $1 trillion in asset value, more than 200,000 miles of transmission lines operating at 230,000 volts and greater, 950,000 megawatts of generating capability and nearly 3500 utility organizations, serving more than 100 million customers (or well over 300 million people). Providing reliable electricity is an enormously complex technical challenge, even on the most routine of days. Unfortunately, this incredible feat of engineering is destined to failure. It’s a sad testament to a country that still leads the world in manufacturing and quality of life. Few of us have control over our electric service. Most of us don’t give it a second thought— except when our monthly bill comes or lights go out. The average American considers electricity an entitlement, rather than a privilege. That’s not the way it is in much of the world. Imagine living in Iraq or India, where countless people rely on generators for their power requirements and are lucky to have electricity only four to eight hours per day. Whoa! That could never happen “here,” you say. Don’t count on it. The issues There are a number of issues facing the power industry that will impact each and every American (and whether we’ll have enough electricity in the future). The most significant of these, in my opinion, involves the clean-air legislation Washington is debating. Ask any investor-owned power-company executive about cap and trade, clean coal and carbon sequestration, and you’ll hear general concern about rising costs and profit margins. A utility must be able to pay investors some return or it won’t have any investors. If it isn’t making money or is constantly operating on the edge, no one will want to lend it any money. What does all this have to do with keeping your lights on? If the Clean Air Act passes as it’s currently written, a number of older (coal) plants won’t be able to meet


the new standard. In fact, several large utilities are already planning to shut down older coal plants in anticipation of the new legislation—due to the cost of bringing them into compliance. What then? Don’t bet on wind or solar to match the power generated by the base-loaded facilities we shut down.

Energy conservation will only cover a portion of the gap between our electricity supply and demand. Utility companies must look out for their investors. They can’t run the risk of building new coal plants only to find out they don’t meet the “new” standards. Nor can they invest in nuclear plants without some government loan guarantee to assist in the high cost of construction. And don’t forget, plans for new coal- and nuclear-powered plants can’t go anywhere without the need—and high costs— to deal with various special-interest groups that dot the power-industry landscape. The reality Energy conservation will only cover a portion of the gap between our electricity supply and demand. The remaining portion must come from base-loaded power plants. Proactive utilities are building gas-fired combined-cycle plants to meet customer demands. It’s a calculated risk, given the spike in natural gas prices in the late ’90s. When all is said and done, however, it is the path of least resistance.

Protecting & Optimizing Your Air Compressors Count on synthetic lubricants to help you do it all!

Jane Alexander, Editor with Michael J. Hawkins ExxonMobil Lubricants & Specialties


ir compressors are everywhere. They’re one of the most valuable and widely used power sources for industrial and commercial businesses in the world. Over the past decade, the marketplace for these workhorses has gone through a dramatic transformation. The need to improve productivity and lower costs has led to significant changes in compressorcomponent technology and designs, with leading manufacturers introducing increasingly advanced units that are more compact— and more powerful—than ever. If your processes require air compressors, protecting and optimizing their performance should be at the top of your to-do list. Consider the following tips. They can help you ensure that your compressors deliver the reliability and performance your operations demand. Protection and optimization start with the correct lubricant In most industrial facilities and many off-highway applications, today’s air compressors operate under extreme pressures and generate extremely high amounts of heat through adiabatic compression. (This is similar to the process used to ignite the fuel-air mixture in a diesel engine.) In these types of operating conditions, high-performance, fully synthetic lubricants offer a number of advantages over mineral-based products. For example, Mobil Rarus SHC 1020 Series oils are formulated with an advanced base oil and a proprietary additive system that assures exceptional resistance to oxidation, enabling them to deliver long-lasting protection and reliability. By comparison, conventional mineral oils often break down when subjected to hightemperature conditions, leading to harmful deposits that can damage critical compressor components.



ROI From Oil Analysis Use of synthetics results in a number of benefits, including… ■ Cleaner compressors, which leads to longer running periods between maintenance intervals ■ Enhanced oxidation and thermal stability, which minimizes sludge and deposit formation, even under extremely high and low temperatures, and extreme load conditions ■ Higher load-carrying ability, which minimizes wear of bearings and gears ■ Increased water separability, which reduces sludge formation in crankcases and discharge lines, as well as blockages of coalescers and inter- and after-coolers ■ Improved rust and corrosion resistance, which protects internal components More protection and optimization “must-dos” Check for air leaks. You’ve heard it before: Running a compressor with air leaks is like driving a car with the emergency brake engaged. It wastes energy, reduces output capacity, shortens equipment life and increases maintenance costs. For example, the air leaking from a typical 1/8” hole consumes about one horsepower of energy. Keep operating pressures at the minimal requirement. This is best accomplished by identifying the maximum application-pressure requirement of the system. To this, add the conveyance pressure loss, as typically about 5 psi are required to move air from the compressor to this application. The sum of these two pressures should be the pressure setting of the receiver tank. For example, if the maximum system application pressure requirement is 75 psi, then the receiver tank should be maintained at 80 psi. Only minor adjustments should be necessary to fine-tune this set-point.

For most companies, quarterly oil analysis is recommended for both reciprocating and rotary screw compressors. Such testing should be used to identify the condition of the in-service lubricant, as well as the presence of any wear metals indicative of a potential developing failure. The presence of any harmful contaminants, such as dirt, water and/or coolant, should also be identified. According to ExxonMobil, its Signum Oil Analysis Program is an advanced, online oil-analysis service that lets users register equipment, specify tests, print out labels required to send samples to ExxonMobil laboratories for analysis, and then download results, all from the convenience of their computers. …JA

Similar to air leaks, running at excessively high pressures results in shortened compressor and component life, along with increased maintenance and repair costs. Increased pressures also result in increased heat, which can significantly shorten the life of compressor lubricants, requiring frequent oil changes. (For every 2-psi reduction in operating pressure, there’s about a 1% increase in efficiency.) To get the most out of your compressor, make sure that intake air filters are routinely replaced and that all induction air piping and manifolds are tight and leak-free. Periodic white-glove inspections of all induction-piping surfaces should be performed to validate that internal surfaces are maintained dust-free. The source of any dirt or deposits found should be immediately traced back to the point of origin and repaired.

Understanding Lube Compatibility Many compressor manufacturers offer their own line of lubricants. These are often supplied under private-label agreements with lubricant manufacturers and blenders. These products are engineered to promote optimal equipment performance, as well as to be compatible with the materials used for internal components like seals and hoses. Before changing lubricants, it is important to consider the new product’s compatibility, not only with the materials of the compressor’s components, but with the previous lubricant used in the unit. The new lubricant’s formulation and

20 |


performance can be compromised if it is not compatible, potentially resulting in increased component wear, accelerated instances of oxidation, degradation of additives and elevated particle count. Since lubricants are engineered with complex chemistries, maintenance professionals are advised to seek the technical advice of an expert lubricant supplier with an in-depth knowledge of compressors. This type of expert will be able to provide data about compatibility testing and instructions for the proper flushing procedures to help promote a smooth conversion.

THE GREEN EDGE Moving automobile manufacturing along. . .

When an auto-parts maker needed heightened performance, a switch to this synthetic was an important part of the solution.


ith downtime at an unacceptable level in an auto-parts maker’s die-casting operation, a solution was needed to not only boost equipment uptime, but also meet higher performance and productivity demands. After an assessment of operating conditions, product chemistry, equipment inefficiencies and performance expectations, specialists from Quaker Chemical Corp. suggested a conversion from water glycol (HFC) fire-resistant hydraulic fluid to a higher-performance product, specifically its biodegradable QUINTOLUBRIC 888 series fireresistant hydraulic fluid (HFD). HFD hydraulic fluids are fire-resistant and do not contain water. They’re usually based on synthetic base stocks

or esters that combine reasonable to good fire-resistant properties with excellent lubrication performance. According to the manufacturer, QUINTOLUBRIC HFD is engineered to maximize performance of equipment that’s designed to operate with customary mineral-oil technology. When conversion at the die-cast operation was complete, operating results showed significant improvement: Pump wear was reduced by 91%, and seal life increased by 250%. The die-caster also noticed that pump and motor noise were reduced and that fluid adjustments were no longer necessary, saving additional time and resources. Based on previous measurements, this end-user could now expect its pumps to run up to 10 years on the QUINTOLUBRIC fluids, compared

with a maximum of two years on water glycol fluids. Quaker notes that the additional material cost of HFDs is outweighed by their benefits, especially where high performance is needed. Furthermore, the QUINTOLUBRIC 888 series products are not only biodegradable, they provide low aquatic toxicity, which makes them appropriate for environmentally sensitive applications. These fluids are approved by FM Approvals, a member of the FM Global group, as a less-hazardous hydraulic fluid. They are also typically compatible with other HFD-U type fluids with similar chemistries, as well as with mineral oils. LMT Quaker Chemical Corp. Conshohocken, PA For more info, enter 30 at

Optimizing Equipment Performance & Reducing Maintenance Costs DuPont’s Krytox has been delivering for more than 50 years.


any maintenance managers, particularly those with equipment operating under severe conditions such as extremely high or low temperatures and/or harsh chemicals, consider frequent equipment failures to be just another cost of doing business. Those failures, unfortunately, can have a devastating effect on a company’s bottom line. The good news is that many causes of equipment breakdown can easily be corrected—and many of the costs curtailed—with proper lubrication. Switching lubricants made the difference Since their first commercial application more than 50 years ago, DuPont™ Krytox® synthetic lubricants have delivered superior, extended performance in a wide range of applications across diverse industries. Today, with new additives for new challenges, Krytox lubricants are still delivering extreme performance under extreme conditions. Thousands of companies around the world have discovered the many advantages of switching to Krytox lubricants. Here are a few examples: ■ A major U.S. electric utility was able to schedule re-lubrication of the bearing in its hot gas fan-control louver once a year instead of once a month. This not only eliminated disruptive and costly monthly production shutdowns, it reduced the number of times workers would be exposed to hazards associated with this maintenance task. ■ A British titanium-ingot manufacturer was able to significantly extend the service life of the seals in the hydraulic rams it uses to remove large ingots from vacuum furnaces. 24 |


Those seals are now replaced every 18 months in planned routine maintenance, instead of every four months. ■ A French airport authority was able to achieve annual savings of US$20,000 - $25,000 on the maintenance of its jet fuel pipeline. Maintenance is now performed every 30 months instead of every four to six months. Unscheduled shutdowns due to valve failures have been eliminated. ■ An American chemical plant was able to improve the performance of its anhydrous ammonia pumps by eliminating shaft wear and doubling the service life of the shaft seals. ■ An Indian manufacturer of textile stenters was able to help its customers extend the re-lubrication interval for the stenter chain bearings from every eight months to once a year. The Krytox value proposition Lubricant selection is key to improving equipment efficiency and uptime—and, ultimately, to saving money on maintenance and lost productivity. It also can help you in your quest to ensure safe operations. While some organizations are reluctant to invest in what they consider to be “more expensive“ types of lubricants, a cost-benefit analysis will quickly show how the right product can contribute to reduced downtime and optimized performance.
