LIQUID RING VACCUM PUMP APPLLICATIONS



POWER GENERATION EQUIPMENT

The Graham liquid ring vacuum pump supplied to the power industry for condenser venting is a two-stage (two impeller) design housed in a single pump body. Our unique internal spray feature ensures the maximum amount of condensing before the gas enters the vacuum pump, much like a direct contact condenser. This feature allows the pump to handle more load because condensation ahead of the pump reduces volumetric flow rate. To achieve capacity requirements, some companies utilize a spray tee ahead of the vacuum pump and air ejector to achieve the design pressure, or even attach a second stage impeller housing to a single stage pump.

All Graham condensers venting equipment is designed to perform per HEI (Heat Exchange Institute). At Graham, every condenser exhauster system we sell is designed to meet the venting capacity requirements specified per HEI at 1 inch HgA.

Graham is the only manufacturer that designs and builds Steam Surface Condensers, Liquid Ring Vacuum Pump Venting Systems, and Liquid Ring Vacuum Pump Waterbox Priming Systems. Our unique experience and understanding of how these systems work together allow us to provide the Engineering Answers the power generation industry requires.

PETROCHEMICAL

Graham has been producing Liquid Ring Vacuum Pump Packages for the petrochemical industry for many years. The applications where our liquid ring vacuum pumps have been utilized are diverse. Some common processes are cumene, phenol, ethylene glycol/ethylene oxide, ethyl benzene/styrene monomer, amines and alcohols, to name a few. We are experienced at supplying vacuum pumps and systems per the requirements of API specifications such as API-681, 610 and 682. As a regular supplier of ejectors, condensers, and heat exchangers to oil refineries, Graham manufactures ancillary system components to the exacting standards required by the petrochemical industry. Material requirements for sour service, such as NACE MRO-175-95 are not a problem.

Combine our liquid ring vacuum pumps with our ejectors and condensers for a hybrid package designed from the ejector suction to the separator discharge, all designed, manufactured and backed by a single company. With a multitude of experience in all of the system components, combined with petrochemical process knowledge, Graham can design and build the right system for any application.

SEAWATER DEAERATION

Looking for the leaders in seawater deaeration vacuum equipment? Graham has produced hundreds of vacuum pumps and ejectors for use on oil platforms throughout the world. You can find our equipment on oil platforms in the Gulf of Mexico, the North Sea, the Persian Gulf and across Asia. At the heart of our systems is our nickel-aluminum-bronze (AB2/BS1400) vacuum pumps, for which Graham is the industry leader in their production.

Nickel-aluminum-bronze offers the best of both corrosion resistance to seawater and economical pricing. It is not uncommon for Graham nickel-aluminum-bronze pumps to be in operation 10 to 15 years or longer than 316 stainless steel pumps in this harsh environment. Often, pumps in this service are supplied with Monel shafts and Xylan coated 316 stainless steel exterior bolting. Mechanical seal selection is determined by the application requirements.

Our deaeration systems don’t stop with the vacuum pump. Systems normally consist of the vacuum pumps, atmospheric air ejectors, baseplates, separator tanks, and other ancillary equipment, such as the motors, couplings, and guards.

Ejectors are normally supplied in 316 stainless steel or Monel. Baseplates are coated in a heavy-duty epoxy consisting of a primer coat, two intermediate coats, and a polyurethane finishing coat. Separator tanks are manufactured from fiberglass-reinforced plastic.

All of our deaeration systems and individual components are designed to work efficiently together, while offering years of trouble-free service.

PHARMACEUTICAL

For drying, laboratory, vapor recovery, house vacuum and everything in between, rely on Graham liquid ring pumps. Graham regularly supplies equipment for use in the pharmaceutical industry. Our liquid ring vacuum pumps are operating in processes the world over, drying product and recovering organic vapors. Liquid ring vacuum pumps are utilized to provide house vacuum on production lines. The choice to utilize liquid ring pumps stems from their unbeatable reliability.

Laboratories often get their vacuum from liquid ring vacuum pumps. A liquid ring vacuum pump's ability to handle slugs of liquid and low change in temperature across the pump, make it a common choice for laboratory systems where flammable mixtures may enter. Our system has also been used on less common applications, such as sampling and weighing equipment.

GROUND WATER REMEDIATION / VAPORT EXTRACTION

TSoil vapor extraction systems often utilize a Graham oil-sealed liquid ring vacuum pump for the vacuum source when low soil transmissivity conditions exist in the contaminated area. This condition requires a much greater vacuum to achieve acceptable vapor removal.

Oil sealed liquid ring pumps have many advantages in these applications. Due to the low vapor pressure of oil, a much greater vacuum can be achieved than with positive displacement blowers or even water sealed vacuum pumps. This allows extraction from wells greater than 30 feet deep. The oil sealed vacuum pump is used in a closed loop system and does not require water for sealing or cooling. This eliminates the need for treatment of contaminated water.

The Graham oil sealed liquid ring vacuum pump package consists of a Graham liquid ring pump, a vapor/liquid discharge separator, an oil mist coalescing filter, an air cooled heat exchanger, all associated piping, and necessary accessories for remote operation. Instruments provided can be explosion-proof rated. We can even supply the oil for the system.

Graham Corporation has a complete line of standard oil sealed liquid ring pump packages pre-engineered for soil vapor extraction and groundwater remediation application, or we can engineer a package to meet any particular specifications.

FOOD PRODUCTION

Graham liquid ring vacuum pumps are commonly used in the production of food. Most of the applications in the food industry are geared toward the removal of water. Concentrating fruit juice, adjusting the boiling point (temperature) of water during cooking, and flash cooling after a food item has been cooked are all common processes where liquid ring vacuum pumps may be found. Materials of construction for these systems are normally cast iron or 316 stainless steel. Many of these systems are supplied with a pre-condenser to remove most of the condensable load upstream of the liquid ring pump. This results in a much smaller vacuum system.

Graham manufactures pre-condensers specifically designed to work in conjunction with our liquid ring vacuum pumps in this service. The result is a single source of equipment supply and guarantee that the condenser and pump are designed to properly function together.



EJECTORS

SURFACE CONDENSERS

Steam Jet Ejectors — the largest vacuum producing devices available — are used in the most demanding of applications. Virtually maintenance-free with no moving parts, they can be fabricated from almost any material, and can be used in every industry that requires vacuum. Ejectors can be designed to operate without steam as their pressurized (motive) source. In addition to operating well into the micron HgA range, they can also operate well above atmospheric pressure.

Graham has mastered Steam Ejector design. Featuring proven, unique internal geometries and tightly tolerance-controlled steam nozzle configurations, Graham ejectors produce very low steam consumption and highly efficient operation. As an experienced provider of Engineering Answers since 1936, Graham maintains the most comprehensive database of actual steam ejector performance information available today.

Combine Graham Steam Jet Ejectors with other Graham equipment, such as Process Condensers and Liquid Ring Pumps, and you have a single source of supply and a responsible, total solution for process equipment needs.

Graham Steam Jet Ejectors are being used in many applications world-wide. Some of these applications include:


Download Ejectors Manual

EJECTORS APPLLICATIONS



CRUDE OIL DISTILLATION

Motor gas and lube oil refineries have a number of applications for ejector systems. Crude vacuum distillation, lube oil distillation, vacuum flasher, and gas oil hydrodesulphurization are the typical applications. Graham ejector systems support the majority of refinery vacuum distillation applications throughout the world. We have computer simulation programs that accurately model vacuum tower overhead hydrocarbons and we have specialized condenser designs for handling mixtures of miscible hydrocarbons and steam in the presence of large volumes of non-condensable gases.

Our vacuum condenser design supports the ejector systems by providing accurate simulation of vapor/liquid equilibrium, optimal condensation efficiency, and minimal pressure loss across the condenser.

Graham is the only manufacturer that designs and builds Steam Surface Condensers, Liquid Ring Vacuum Pump Venting Systems, and Liquid Ring Vacuum Pump Waterbox Priming Systems. Our unique experience and understanding of how these systems work together allow us to provide the Engineering Answers the power generation industry requires.

PETROCHEMICAL PROCESSES

Petrochemical processes are vacuum intensive and there are requirements for single, two, three, and four stage ejector systems. Common processes include cumene, phenol, ethylene glycol/ethylene oxide, ethylbenzine/styrene monomer, amines, alcohols, and caprolactam, to name a few. Graham has a wealth of knowledge in the design, application, and integration of ejector systems into petrochemical applications.

EDIBLE OIL DEODORIZATION

Edible oil plants use Graham ejector systems for deodorization. These are four-stage ejector systems, operating in the range of 1 to 3 torr. Reliable operation is critical to provide proper deodorization of the oils. Other ejector applications in edible oil refineries include vacuum bleaching, hydrogenation, deaeration, and interesterification. Graham also provides ECOfreeze vacuum systems for edible oil deodorization.

ORGANIC MOTIVATED SYSTEMS

Use of alternative motive fluids may offer an advantage in specific applications. Graham has proven installations using ethylene glycol, monochlorobenzene, cyclohexane, methanol, phenol, and refrigerants as the motive fluid. Customers consider ejector systems using motive fluids other than steam under any of the following conditions:

  When there is a need to recover product for use or disposal without water contamination and associated expense of removal

  When solids are present or process vapors deposit in ejectors, but dissolve in an organic fluid

  When backstreaming of steam into the process cannot be tolerated

  When the presence of water may introduce a serious corrosion problem

  When contaminant scrubbing is easier in the absence of water

  When there is a desire to reduce or eliminate air and water volatile organic compound contamination

The main advantages of using an organic fluid for an ejector are the motive fluid acts as a solvent for the process vapors, the process is not contaminated with steam/water, chemical treatment problems are minimized, and the total energy requirements are considerably less than if steam were used as the motivating fluid. An organic motivated ejector system most often is a packaged, self-contained system that includes ejectors, condensers, a vaporizer, coolers, pumps, controls, piping, all auxiliaries, and packaging.

FERTILIZER PLANT OPERATIONS

Urea plant vacuum systems are specialized in that the design must incorporate features in the vacuum condensers due to exothermic heat reaction liberated by chemical reactions that occur. The design requires a combination of vapor-liquid and chemical equilibrium. It also is necessary to minimize the amount of ammonia gas exiting the vacuum system.

Graham has installed a number of urea plant vacuum systems throughout the world that are providing excellent performance, in many cases, they are running at capacities in excess of 100% without sacrificing vacuum in the concentration vessels. Graham also has provided a number of high pressure carbamate liquid eductors where high pressure carbamate solution is boosted in pressure with liquid ammonia for return back to the reactor.

THERMAL COMPRESSORS

Thermal compressors (or Thermocompressors) boost an intermediate steam load to a higher pressure with high-pressure motive steam. A common application is in vacuum concentration or evaporator service. Efficient thermal compression operation is vital for economic operation of the evaporation plant. Graham continues to develop improved thermal compressor designs to reduce energy consumption.

HYBRID VACUUM SYSTEMS

when the application calls for reducing motive steam usage by combining ejector and liquid ring vacuum pump technology, Graham manufactures both. A hybrid vacuum system will have ejectors for the primary (high vacuum) stages and a liquid ring vacuum pump will replace the last ejector stages. This provides an advantage of reducing motive steam consumption by replacing the last ejector stages with a liquid ring pump.

METALS VACUUM DEGASSING

Micron range ejector systems are required for metals vacuum degassing applications. Graham has supplied a number of installations where ultimate suction pressure is 10-30 microns.

SPACE SIMULATION

High altitude or space simulation requires large multi-stage ejector systems. Graham has supplied a number of government agencies with these specialized vacuum systems.



HELIFLOW HEAT EXCHANGER

SURFACE CONDENSERS

The Graham Heliflow Heat Exchanger is uniquely designed and engineered to handle difficult heat transfer applications. Graham created the Heliflow to be exceptionally versatile, yielding heat transfer rates that can be more than 40% better than typical shell and tube designs. The Heliflow Heat Exchanger encompasses a spiral coil, comprised of multiple parallel tubes mounted within a casing. The case/coil construction creates a spiral flow path providing true counter flow. Each application is specially engineered for an optimal balance of thermal and hydraulic requirements, resulting in maximum heat transfer efficiency. High pressure, specialized materials, cyclic operation, temperature extremes and other conditions can be handled without a problem. The Graham Heliflow Heat Exchanger has years of proven service, in thousands of applications throughout the world, with high quality performance always guaranteed.

The many advantages of the unique Graham Heliflow make it an efficient heat exchanger for a wide range of applications; some of which include:


Download Heliflow Heat Exchanger Manual

HELIFLOW HEAT EXCHANGER APPLLICATIONS



LIQUID TO LIQUID

The Graham Heliflow is ideally suited for applications that have a liquid-to-liquid service requiring a heat exchanger.

When designing the exchanger, the "dirty" fluid should be on the shellside of the unit. The Heliflow makes shell side cleaning easy. Cleaning can be done in-place, without breaking shellside or tubeside pipe connections. The flow pattern is 100% countercurrent that maximizes the temperature differential and thermal efficiency.

CRYOGENIC

Graham has conducted extensive research and development in the area of cryogenic vaporizers. Our research and many years of proven experience in this area confirm that the Heliflow heat exchanger is excellent for cryogenic applications. The unique tube coil of the Heliflow can easily accommodate the large temperature differentials that are typical in cryogenic units.

Heliflow Heat Exchangers often use cryogenic fluids as the cooling medium; alternately, Heliflows can be used to vaporize fluids, such as N2, O2, CO2, or other fluids.

EDIBLE OIL DEODORIZATION

Edible oil plants use Graham ejector systems for deodorization. These are four-stage ejector systems, operating in the range of 1 to 3 torr. Reliable operation is critical to provide proper deodorization of the oils. Other ejector applications in edible oil refineries include vacuum bleaching, hydrogenation, deaeration, and interesterification. Graham also provides ECOfreeze vacuum systems for edible oil deodorization.

BLOWDOWN

Boiler blow down and process sample coolers are perfect applications for a Heliflow heat exchanger. The compact size of the Heliflow fits into tight spaces. Also, the Heliflow design can withstand the cyclic nature of blow down service.

NATURAL GAS HEATERS

When natural gas is passed through a pressure reducing station, it decreases in temperature. The compact Heliflow design is often used to increase the temperature of the natural gas.

VENT CONDENSERS

Heliflow Heat Exchanger technology is at the heart of Graham's vent condensers. Vent condensers are often used on storage tanks to reclaim products contained in the tank and control the harmful emissions that escape from the tank to atmosphere. During the day, the sun heats the fluid in the tank. The increase in the system's temperature will cause the vapors in the tank to expand and increase vaporization of the volatile components as their vapor pressures increase. By installing a vent condenser on the vessel, the condensable vapors are reclaimed and refluxed back into the storage tank.

In addition to the venting caused by temperature changes, vapors are exhausted to atmosphere as the tank is filled. The vent condenser experiences the greatest thermal duty when the tank is being filled. The heat exchanger, therefore, should be sized based on the filling case.

Graham has taken the lead in reducing VOC (volatile organic compound) emissions with our design of specialized vent condensers. These units often are used to recover valuable product and reduce the load on downstream pollution control equipment at the same time.

 Permits sub-cooling of the condensate


MECHANICAL SEAL COOLERS

Keeping the mechanical seal faces cool is extremely important in extending the operating life of mechanical seals. The unique design of the Graham Heliflow facilitates superior cooling of the seal flush fluid as compared to traditional mechanical seal coolers.

Heliflow seal coolers can be fitted with vent connections which enable the units to meet the venting and draining requirements of API 682. In addition, Heliflow seal coolers have the ability to thermosiphon in the event of a pumping ring failure.

API flush plans 21 or 23 are the common arrangements for configuring mechanical seal cooling systems. In Plan 21, the product from the pump discharge is circulated through a valve or orifice and then flows through a Heliflow seal cooler where it is cooled before returning to the mechanical seals. In API Plan 23, the product is recirculated from the stuffing box through the Heliflow and then back to the mechanical seal.

Standard models are available in 316 stainless steel tubeside and cast iron shell. Options include 304 stainless steel, titanium, 70/30 cu.ni. tubes, 316 stainless steel and cast steel shell materials. Units can also be constructed to ASME Section VIII, Division 1 Code if desired.

Sizing software is available from Graham to assist in selecting units for both API Plans 21 and 23.


API 682 COMPLIANT UNITS

Standard Heliflow units do not conform with the tubing recommendations of API 682, however, specially designed units are available, which include 3/4" diameter x .095" wall thickness tubes to provide complete compliance with the standard.

COMPRESSOR INTER/AFTERCOOLERS

Heliflow Heat Exchangers are preferred for high pressure service, and are often used as inter and after coolers to cool the gases handled by reciprocating type compressors. Typical design pressure is 2500-5000 psig, however, units designed for up to 15,000 psig are available. Graham has extensive experience in engineering, design, and fabrication of units for compressor service.

SUPER CRITICAL FLUID

Supercritical water oxidation (SCWO) is a cutting edge technology developed for the treatment of hazardous waste solutions. This method uses high pressure, high temperature water at its supercritical state of 3200 psig and 705 degrees F. During this process, oxygen and the supercritical water are injected into the waste stream. The waste contaminants are oxidized, transforming them into carbon dioxide and other harmless substances.

This process is cost competitive and more environmentally friendly than traditional disposal methods, such as landfill or incineration.

Specially designed Heliflow Heat Exchangers with spherical casings are used to withstand the high operating pressures and temperatures required. These units are used to cool the reactor effluent, to generate steam, as a feed interchanger, and as sample coolers.

FEEDWATER PREHEATERS

Heliflow Heat Exchangers can save energy as heat recovery economizers. Waste heat is recovered and utilized to preheat incoming make-up water that is used in boilers or for other applications.

LETHAL SERVICE

Specially designed Heliflow Heat Exchangers are available for use when handling lethal liquids or vapors. These units are built to strict manufacturing, welding, and quality control specifications and include specially developed features to provide confidence when handling lethal fluids.

STEAM OR PROCESS FLUID VAPORIZERS

The Heliflow Heat Exchanger design is often used to provide a compact vaporizer. The coiled tube bundle promotes nucleate boiling, and can easily handle the stresses caused by thermal expansion and cycling. Steam or other high temperature sources are often used to vaporize nitrogen, oxygen, carbon dioxide, hydrogen, methane, ethylene, various hydrocarbons, and many other fluids. Vaporizing can be achieved either shellside or tubeside according to process requirements.

BOILER OR PROCESS SAMPLE COOLERS

The compact footprint of the Heliflow Heat Exchanger, along with its ability to handle frequent cycling and wide temperature differentials make this unit ideal for use in sample cooler applications.

HOT WATER HEATERS

Heliflow Heat Exchangers can heat water using steam or high temperature hot water (or other fluids) as the energy source. When control of the water temperature is important, temperature control valves are often used with the Heliflow design.

If the water flow rate varies, and outlet temperature must be controlled, Graham offers our packaged MicroMix II instantaneous, steam-fired, hot water heaters.

HIGH TEMPERATURE

A benefit of Heliflow Heat Exchangers at higher temperatures is the ability of the coil to flex as it is heated. As the tubes are heated, they grow due to thermal expansion. Because the Heliflow bundle is free to move, the units can undergo many years of cyclic operation without problem.

A major drawback for many other types of exchangers is reduced operating life when working at higher temperatures, or the exchanger must include expensive expansion joints. A Heliflow Heat Exchanger is the best choice for high temperature applications.

FREEZE CONDENSERS

Freeze condensers fall into two categories; the first includes vapors that condense, then freeze in the heat exchanger. The second category typically includes nonfreezing condensables mixed with water vapor or another component, which does freeze.

Both applications are similar in that the objective is to condense and remove from the vent stream as much of the vapor component as possible. The most effective method is to cool the vapor below its freezing point, however, once a component begins to freeze, the heat transfer rate is gradually decreased. To obtain the best efficiency, often two parallel units are used. One unit operates, while the other undergoes a thaw cycle.

Graham is uniquely experienced in the field of freeze condenser technology. Our Heliflow Heat Exchangers can be provided based on system requirements. Years of experience and numerous research projects enable Graham to provide "Engineering Answers" tailored to specific applications.

HYDRAULIC/LUBE OIL COOLERS

The coiled tube geometry of the Heliflow Heat Exchanger provides increased heat transfer efficiency, making these units ideal for use as oil coolers.



PROCESS CONDENSERS

SURFACE CONDENSERS

A properly designed Graham Condenser between the process and vacuum producing equipment will yield significant advantages. The use of a process vacuum condenser can permit significant reduction in the size of the vacuum producing equipment. A condenser can recover for reuse valuable product that’s carried from the process with non-condensable gases. It can reduce the amount of wastes produced by the vacuum system and lower the process operating cost. Graham Process Condensers can be designed for a wide variety installations: direct contact or surface type, mounted horizontally or vertically, freeze condensation or conventional condensation type.

Matching the Process Vacuum Condenser with vacuum producing equipment is the best way to meet the process objectives. Graham manufactures both the Process Condenser and the vacuum producing equipment. This single-source responsibility provides a unitized system that is matched to the process.Some of the applications where you may see the Graham Process Condenser being efficiently utizilied are:


LIQUID RING VACCUM PUMP APPLLICATIONS



CRUDE OIL VACUUM DISTILLATION

Refinery vacuum installation processes may elect to use a process condenser ahead of an ejector system. This will depend on the operating pressure of the process and the volatility of the overhead process vapors.

Graham has proven installation experience and has provided numerous systems throughout the world where vacuum condensation ahead of an ejector system is used. The overhead load from a distillation vessel is a mixture of complex hydrocarbons, steam, and a large volume of non-condensable gases. The application is sophisticated due to the complex vapor-liquid equilibrium calculations and the design of the process condenser must minimize pressure drop. By keeping pressure drop to a minimum, condensation efficiency is maximized and the size and operating cost of the energy-intensive ejector system are kept to a minimum.

PLASTICS, RESINS & FIBERS

In the manufacture of plastics, resins, and fibers, or other petrochemical processes, there often is a requirement for a process vacuum condenser between the vacuum vessel and vacuum producing equipment. These applications often involve high vacuum with large volumes of condensable vapors that are to be condensed in the process condenser. Normally, non-condensable gas flow rate is not too significant, but the challenge is to minimize pressure drop and maximize hydrocarbon condensation. The loading may contain hydrocarbons that have high freeze point temperatures and the tube wall must be maintained above the freeze point.

Graham has specialized designs where the vacuum condenser will mount directly atop the vacuum vessel. This minimizes pressure drop, thus improving condensation in the condenser and reducing the size of vacuum producing equipment.

ECOfreeze

removing process vapors entirely in the process condenser and before they can enter the vacuum producing equipment offers significant advantages. The Graham ECO freeze System has two process condensers; one operates in an ice-building mode, while the other undergoes a defrosting. By trapping the process vapors in the condenser as a solid it results in the vacuum equipment handling non-condensable gas only. This will significantly reduce the size of the vacuum producing equipment and minimize wastes produced by the vacuum system.

COUPLINGS



KD DICS COUPLINGS

KD Series of flexible shaft couplings provides reliable transmission of mechanical power from driving to driven machine where a low- maintenance, non-lubricated coupling is required.

KD® Disc Couplings are specifically designed to accommodate general purpose drive system applications such as centrifugal pumps, compressors, generators, cooling towers, machine tools, printing and pulp and paper machines.

KD® Couplings transmit torque and provide for both angular and axial misalignment between shafts with a coupling comprised of shaft mounted hubs connected through flexible disc packs with spacer or sleeve assemblies.

All KD® Couplings use stainless steel discs as flexible members, providing high strength and good corrosion resistance. The streamline disk pack design results in the reaction load on equipment bearings being minimized. These disc pack couplings are inherently self-centering; additional provision for limited end float is not required.

Most disc packs are unitized and, along with self-locking nuts, they greatly reduce the number of loose parts, thus simplifying installation and replacement. KD® Disc Couplings are now available in an expanded range of sizes and styles suitable for common installations. Or if you need something special, we can design a coupling to meet your specific requirements.

GREASE FOR HIGH PERFORMANCE GEAR COUPLINGS



GREASES DESIGNED EXCLUSIVELY FOR SHAFT COUPLINGS

LIQUID RING VACCUM PUMP

As the world’s leading manufacturer of flexible shaft couplings, KOP-FLEX was one of the first companies to develop greases especially for use as shaft coupling lubricants. KOP-FLEX recognized that couplings must use greases with certain special qualities, and as the company most likely to understand these very special needs, KOP-FLEX knew that most commercial grease formulations will not insure adequate performance and are not ideal coupling lubricants.

Coupling grease, unlike bearing or general purpose grease, must withstand the centrifugal forces created by a rotating coupling. Coupling greases from KOP-FLEX® brand couplings are specifically formulated to resist the high centrifugal forces associated with all applications, including slow motor speeds. These forces can cause the all-important base oil to separate from the soap thickeners and additives. Unlike greases with lithium-based thickeners, KHP and KSG greases use polyethylene thickeners, with a density closer to that of oil, and are therefore much less susceptible to separation. Heavier thickeners and additives can separate and migrate into the gear teeth or other working parts, displacing the lubricating oils from where they are most needed.


KSG STANDARD COUPLING GREASE:

KSG is an NLGI Grade #1 coupling grease with E.P. additives for use in any grease-packed coupling, such as gear, grid, and chain-type couplings, in standard industrial service. Superior to the commonly available greases adapted to coupling use, KSG was developed specifically as a coupling lubricant.


KHP HIGH PERFORMANCE COUPLING GREASE:

KHP grease is an NLGI #1 grease with E. P. Additives which exceeds the design requirements needed for extended operating and republication intervals. KHP grease is recommended for high-speed grease lubricated gear couplings in petrochemical, process, and utility industries.


WAVERLY* TORQUE LUBE ‘A’ GEAR SPINDLE GREASE

Torque Lube ‘A’ was developed to solve the special lubrication problems of relatively low speed, highly loaded gear spindle couplings used extensively in metal rolling mills. Torque Lube ‘A’ has consistently provided protection in applications demanding a lubricant with extreme pressure protection, high heat and shock loading, excellent wear protection, and resistance to water washout. This grease is compounded with a concentration of Molybdenum Disulfide and other additives to provide extreme pressure protection. These additives cannot resist the effects of centrifugal forces; therefore, WAVERLY* TORQUE LUBE ‘A’ should not be used in a standard coupling without consulting KOP-FLEX.

Our diaphragm couplings transmit torque from the driving shaft via a rigid hub, then through a flexible diaphragm to a spacer. While transmitting torque to the spacer, the diaphragm deforms to accommodate misalignment. The spacer, in turn, drives matching components attached to the driven equipment.


KOPFLEX REVOLUTIONIZED DIAPHRAGM DESIGN

LIQUID RING VACCUM PUMP

Kop-Flex has manufactured extremely reliable, maintenance-free diaphragm couplings since the mid-1970’s, with well over ten million hours of operation. Our early experience making diaphragm couplings led us to reexamine prevailing diaphragm design. In 1989, we developed and patented a unique refinement technique eliminating the need for welds and allowed for field replaceable flex elements. In addition, we began to take full advantage of our FEA and computer aided, manufacturing techniques. The result? Kop-Flex High Performance diaphragm couplings combine the positives of competing diaphragm couplings with additional design features. It is also easier to replace a competing diaphragm coupling with a superior Kop-Flex coupling.

Advantages: Fast ∓ Easy Repair, Extremely Repairable


The Kop-Flex diaphragm is bolted (not welded) to the spacer. You can remove our diaphragm without moving the equipment or removing the rigid hub. This reduces downtime and expense. It is much easier to stock or reorder a replaceable Kop-Flex diaphragm than a big welded assembly. And our no-weld design diaphragm is more reliable.

Patented Donut Shape: Handles more misalignment, Greater range of torsional stiffness


The unique Kop-Flex diaphragm profile follows the modified power function toward the center. Unlike any competing designs, the diaphragm doubles back before it's attached to the spacer. Rather than a flat or wavy disc, the Kop-Flex brand diaphragm is more like a donut shape and is one piece of stainless steel. In effect, we have more diaphragm in a given space. This allows the Kop-Flex diaphragm to handle more torque, axial misalignment, or angular misalignment than competing designs of comparable size.


SPECIALLY CONTOURED, ONE-PIECE DIAPHRAGM

Advantages: Simple ,less hardware | Cost competitive | Easy to customize | Quick Delivery

Like any diaphragm coupling, our ability to transmit torque and handle misalignment depends chiefly on the thickness distribution (or profile) of the diaphragm. Unlike competing designs, we use a single stainless steel diaphragm. This eliminates the need for extra bolts, rivets, splines and filler rings. It also greatly simplifies the task of shaping the perfect diaphragm, since we need only one diaphragm per end. We use a modified profile based on extensive FEA. The thickness of the diaphragm varies so stress is distributed evenly when the diaphragm flexes under the simultaneous effects of torque, speed, axial misalignment and angular misalignment. Also, unlike competitors, Kop-Flex translates CAD and CAM into quick deliveries. These techniques stand behind our ability to customize diaphragms for special applications.



MIDDLE EAST COOUPLING REPAIR & MAINTENANCE CENTER

BITCO (Binzagr International Trading Company) have planned to start local coupling maintenance, repair and assemble activities in our Jubail workshop in mid of 2017 with Regal Beloit Kopflex.

We learned and initiate the project for coupling interchangeability in Saudi Aramco Riyadh Refinery plant, they have more than 900 motors and with Saudi Cement has more than 600 fans most of them driven by couplings. In such situations end users have to deal with large variety of spares and also multiple vendors. The availability of spares and coupling health cannot be ensured after the scheduled maintenance shutdowns, as it is practically not possible to focus on the small but important part such as coupling. Our clients are agreed that the proposal to standardize the couplings in the plants, to approximately 8 models and spares list reduced to approx. 20 part numbers from only one vendor with service contract will bring in big value addition.


THIS WILL VALUE ADDITION WILL BE IN TERMS OF:

  Ease of spares planning

  Ease of procurement

  Great advantage of interchangeability

  Very reliable stock of spares

  Possible price advantage because of quantity procurement.

  One stop shop for coupling
