This is achieved by a servo piston acting on one end of the swash plate working against the combined effect of the off-setting forces of the pistons and centering spring on the other end. The control spool acts as a metering valve which varies the pressure behind the servo piston.As shown in Figure 1, the amount of flow produced by the Parker Piston Pump is dependent upon the length of stroke of the pumping pistons. This length of stroke, in turn, is determined by the position of the swash plate. Maximum flow is achieved at an angle of 15-17degrees. The rotating barrel, driven by the prime mover, moves the pistons in a circular path and the piston slippers are supported hydrostatically against the face of the swash plate. When the swash plate is in a vertical position, perpendicular to the centerline of the piston barrel, there is no piston stroke and consequently no fluid displacement. When the swash plate is positioned at an angle, the pistons are forced in and out of the barrel and fluid displacement takes place. The greater the angle of the swash plate, the greater the piston stroke.Control OptionsBARRELPressure Compensated Control (OMIT)The swash plate angle controls the output flow of the pump. Swash plate angle is generated by the hydraulic force of the pumping pistons and the mechanical force of the swash plate bias spring. Control of the pump’s outlet flow is obtained by over-riding the force of the pumping pistons and bias spring with the hydraulic force of the servo piston by means of internal porting. Pressure is connected from the outlet port to the servo piston via a compensator spool.The compensator spool is held against the spring guide by the outlet pressure. When the outlet pressure reaches the setting of the compensator control, the compensator spool moves, allowing outlet pressure oil to be metered into the servo piston. This metered oil provides adequate force to power the servo piston and override swash plate forces. The outlet pressure causes the servo piston to move which reduces the angle of the swash plate and thereby reduces the pump’s output flow. When flow is again demanded by the system, the outlet pressure will momentarily fall allowing the compensator spool to move. This movement closes off the outlet pressure to the servo piston and vents the servo piston to case. The result of this venting allows the swash plate forces to move the swash plate angle to maximum displacement, thus responding to the demand for additional flow. Note that the compensator spring chamber is vented to the pump case via a hole internal to the compensator spool.PORTRemote Pressure Control (M)The pump swash plate actuation is identical to the standard pressure compensator but can be controlled via a remote pressure control.Remote control of the pump output pressure can be achieved by controlling the pressure at port A, Figure 3 on the compensator. Flow is metered through the orifice in the spool from outlet pressure into the spring chamber. The spring chamber pressure is limited by an external relief connected to port A. The controlled pressure at port A is sensed at the differential spring chamber. The compensator spool will move to the right when the pump outlet pressure reaches a force equal to the differential spring setting plus the controlled port pressure setting. When the spool moves to the right, outlet pressure oil is metered to the servo piston and the pump swash plate angle is controlled accordingly. With this option the pump outlet pressure can be controlled and varied from a remote location.This control also incorporates a pressure limiting feature preset at the factory. When the pressure in the differential spring chamber reaches the maximum relief setting, the dart unseats allowing the spring chamber to vent to the pump case and limits the maximum pressure attainable.Control OptionsCatalog HY28-2662-CD/USFlow Control (Load Sensing) (A)Figure 4 shows a PVP pump with flow control. The control is identical to the remote pressure compensation control except for an integral orifice, a solid compensator spool and adjustable differential pressure control. Port A is connected downstream of an orifice (variable or fixed) to sense the actual working pressure required. This pressure plus the differential spring force act on the right side of the compensatorspool and will urge the spool to the left until output pressure acting on the left side of the spool balances the forces. As the load increases, output pressure will increase and maintain a constant differential pressure across the orifice and thus a constant flow.Maximum pressure is limited by the internal dart setting.This setting is adjustable up to the maximum preset at the factory.Variable Volume Piston PumpsSeries PVPControl OptionsPORTCatalog HY28-2662-CD/USPressure & Power Control (H)This control option is a T orque Limiting Control, but for constant speed applications it is generally referred to as a Horsepower Control. This control works in conjunction with the Remote Pressure Compensator,control option “M”. A second pressure control device called a horsepower control block, is assembled to the main pump housing. The HP block is plumbed to one of the ports on the remote compensator via steel tubing.The control dart in the HP block and the maximum pressure compensator dart in the remote compensator are connected in parallel. What makes the control dart in the HP block different from any other external relief valve is the pressure setting is mechanically linked to the pump swashplate angle.The cracking pressure of the HP dart is generally lower than the cracking pressure of the remote compensator differential spring cavity is lowered allowing the compensator spool to meter system pressure in the servo piston. As the servo piston extends, it rotates the swashplate and in turn rotates the HP cam. As the cam rotates it increases the force on the HP dart control spring. As the system pressure is allowed to increase,the pump gradually reduces its stroke (flow). When the system pressure reaches the setting of the maximum pressure dart the normal action of the remote compensator takes over. If the HP control is set low enough, the pump may reach zero stroke before the system pressure ever gets a chance to open the maximum compensator dart. This should be considered when making low power settings on systems requiring high working pressures.Variable Volume Piston Pumps Series PVPControl OptionsCatalog HY28-2662-CD/USPressure, Power & Flow Control (C)Refer to the previous section(s) on Flow Control and Power Control. This is another case where multiple controls can be combined in parallel. Since the Power Control is just a special version of Remote Pressure Control, it can be combined with the Flow Control (Load Sense) option. The main point to remember here is that the pressure drop which is required to begin and maintain compensation comes from an external device (such as a proportional valve). This sensed pressure drop will control flow until one of the limits of the other controls has been exceeded. The pump will always respond to the lowest control setting for any given pressure. In addition to Load Sensing, Power Control,and on-pump Pressure Control, Remote Pressure Control can also be included in this parallel device package. There is a remote port on the compensator body and one on the HP Control body, either of which may be used for remote pressure control. The important concept to remember in load sense circuits is that each pressure control device in and connected to the compensator must be protected from saturation. For this reason, use only the uppermost port on the compensator for connection of the load sense line and insure that an appropriate orifice is installed. All control options using a load sense compensator spool are supplied with this orifice.Variable Volume Piston Pumps Series PVPControl OptionsCatalog HY28-2662-CD/USHi/Lo Power Control (HLM)(Available with PVP41 and PVP48 Only)The graph shown below represents the flow-pressure characteristics of a Hi-Lo control for PVP pumps. There are up to four separate adjustments that must be made with the pump controls to get a particular setting, all of which influence the shape of the curve. To get the proper settings, it is very important that all pertinent information is supplied with each Hi-Lo pump ordered.As you can see from the graph below, there are two peak power points. Our intention is to have the same magnitude of power required for both peaks. Of course many combination of settings are possible but specification of the settings becomes very difficult. To make factory settings, we need to know the required flow (applicable if pump has a maximum volume stop), the shaft speed , the required Power limit , and the compensation pressure . Based on these requirements, we will adjust the low pressure set point and the reduced flow set point of the Hi-Lo control to best match the requested parameters called out on the order.Important note: As with power controls, not all combinations of flow, power, pressure, etc. are possible.pressure or in a de-stroked condition can have a much lower overall efficiency than expected. The other thing to keep in mind is that the pump will require the peak power at only two points. All other operating pressures will require less than maximum power and therefore the pump will deliver less hydraulic power in the appropriate ratio based on the actual pump efficiency at those conditions.System PressureO u t l e t F l o wTypical Hi-Lo ControlFlow/Pressure CharacteristicsVariable Volume Piston Pumps Series PVPControl OptionsPVP SERIESPRESSURE & POWER COMPENSATORCONTROL OPTION "HLM"Performance InformationSeries PVP16 Pressure Compensated,Variable Volume, Piston PumpFeatures•High Strength Cast-Iron Housing for Reliability and Quiet Operation•Optional Inlet/Outlet Locations for Ease of Installation•Replaceable Bronze Port Plate •Replaceable Piston Slipper Plate•Thru-Shaft Capability SAE A Pilots Offered •Low Noise Levels - Promote More Comfortable Operating Environment •Fast Response Times•Metric Pilot Shaft and Ports AvailableControls•Pressure Compensation•Remote Pressure Compensation •Load Sensing•Torque (Power) Limiting•Adjustable Maximum Volume Stop •Low Pressure StandbySchematic Symbol(Basic Pump)Quick Reference Data ChartDisplacementPump Delivery † Approx.

One of the leading causes of cylinder failure is seal failure . Parker offers sealing options that cover the widestassortment of applications in the market, ensuring you can get the right seal for your job. The following bulletin will look at Parker cylinders by series and their sealing options to better assist in your specification of sealing requirements.Parker Sealing TechnologyProvides Unmatched Leak Protection on allIndustrial Hydraulic and Pneumatic CylindersHP - Polyurethane Piston SealKP - Filled PTFE Piston Seal RP - Thermoplastic SealWP - Mixed Media SealJewel Gland2H Piston Seal Types:One of Parker’s core cylinder series, the 2H is a 3000 psi NFPA tie rod hydraulic cylinder available in 1.50”-6.00” bore diameters and up to 240” stroke length. The 2H series piston seal kits utilizeParker’s new universal piston seal design, which addresses the performance balance between low pressure sealability, low friction, extrusion resistance and seal life. One piston style is used for all piston seal and wear ring configurations and will suit all application requirements. This reduces the complexity in maintaining cylinders, saving time and cost.Parker offers 4 unique seal types , asshown in the chart below, that when paired with the right seal class will provide the right sealing for your application. Seal class types are located on page 4.Contact Information:Parker Hannifin Corporation Cylinder Division 500 South Wolf Road Des Plaines, IL 60016phone 847-298-2400******************/cylinder2H Rod Sealing System:Parker’s TS2000 threaded Jewel Gland sealing system acts as an automatic check valve that prevents any appreciable amount of oil to leak past the seals.As the rod strokes out, the TS2000’s multi-sealing edges maintain contact with the rod. This provides a cutting action to shear oil from the rod, allowing the rod to pass out of the rod seal practically dry. Any oil that remains on the rod is stopped by the inner lip of the Wiper-seal and held between it and the rod seal. On the return stroke any dirt collected on the rod is wiped off by the outer lip of the Wiper-seal. At the same time, any oil trapped between the Wiper-seal and the rod seal is returned into the cylinder. The TS2000 Jewel Gland is easily removed for service without loosening tie rods and disturbing the pressure envelope.Additional 2H Sealing Options:For environments that contain fine abrasive particulates Parkerrecommends the Parker Crown Wiper™ for Series 2HD. The 3000 psi NFPA tie rod hydraulic 2HD cylinder is the next step up in Parker’s 2H line for applications that require increased durability and is also available in 1.50”-6.00” bore diameters and up to 240” stroke length. The Crown Wiper is a proven superior alternative to piston rod end boots or metallic wipers that can ingest particulate. It has a sharp leading edge to effectively clean the piston rod and a beveled shape to prevent contaminant intrusion by channeling it away from the gland. It also acts as a secondary seal to wipe clean any oil film adhering to the rod on the extend stroke. Standard Crown Wiper material for Seal Class 1 and 2 service is durable polyurethane. Optional FKM material is available for Class 5 service.The Parker Buffer Seal, installed ahead of the primary rod seal, protects the primary seal from the effects of pressure spikes. The result is increased primary rod seal and wiper seal performance life when in severe applications. Both seals provide superior protection against harmful contamination that can damage cylinders causing unnecessary downtime. Buffer Seals are available in class 1, 2, 3, 4, 5 and 6.Buffer SealSealing for RDH:Parker’s heavy-duty hydraulic round-line cylinder series, the RDH is a 3000 psi cylinder available in 1.50”-8.00” bore diameters and up to 240” stroke length. The RDH offers a Tri-Lip Rod Seal and Bi-Directional Piston Seal with proven leak-free performance. Durable polyurethane material is used to maximize seal life. Nitrile end seals and backup rings on a smooth bore of thecylinder body provide optimal sealing and elimination of extrusion problems. Composite rod and piston wear rings are internallylubricated for reduced friction and formulated for heavy-duty, load-bearing applications. Standard rod material is case-hardened, hard chrome plated and polished to an optimum finish. And since we use Parker seals, all seals have immediate availability in other popular compounds.Sealing for 2A/2AN:Parker’s heavy-duty pneumatic cylinder series, the 2A is a 250 psi NFPA tie rod cylinder available in 1”-14” bore diameters and up to 240” stroke length. The 2A provides a serrated lip-seal in its rodgland that has a series of sealing edges which take over successively as pressure increases, providing efficient sealing under all operating conditions. The double lip wiper-seal acts as a secondary seal,cleaning the rod on the return stroke. Its outer lip prevents the ingress of dirt into the cylinder, extending the life of the gland and seals, minimizing costly replacements.Parker Series 2AN, the non-lubricated version of the 2A, and comes with Non-Lubricated Rod Seals. These seals with special rounded sealing lips are supplied as standard for all non-lubricated applicationsand provide all the same benefits as the 2A rod sealSealing for 3L:For use in applications that require lighter duty than the 2H, Parker’s 3L series is a 1000 psi NFPA tie rod hydraulic cylinder available in 1.00”-8.00” bore diameters and up to 240” stroke length. The 3L’s Piston Lip-seals provide zero leakage under static conditions. Seals are self-compensating to conform to variations in pressure, mechanical deflection, and wear, and have back-up washers to prevent extrusion.The 3L Series also utilizes the TS2000 Rod Seal System with its proven leakproof design. It is completely self-compensating and self-relieving to withstand variations and conform to mechanical deflection that may occur. All these features result in a cylinder seal that will withstand the rigors of your applications reducing maintenance costs.CHE/CHD Seal Design:Parker offers two compact hydraulic cylinders, the 140 bar aluminum CHE with up to 150mm stroke length and the 207 bar steel CHD with up to 100mm stroke length, both are available in 20mm to 100mm bore diameters. These compact cylinders include 4 key elements to keep your cylinder leak free:1. Primary Seal – polyurethane rod seal with multiple sealing edges is self-compensating and self-relieving to withstand pressure variations and conform to mechanical deflection that may occur.2. Secondary Seal (Rod Wiper) – wipes clean any oil film adhering to the rod on the extend stroke and cleans the rod on the return stroke.3. Bi-Directional Piston Seal – Polyurethane seal ring with energizer provides leak-free performance.4. Non-Metallic Wear Band – improves resistance to bearing loadsNon-Metallic Wear BandPrimary SealBi-DirectionalPiston SealPiston SealSeal Classes:deterioration from fluid incompatibility or premature wear.expertise in sealing technology. This expertise provides ourcustomers with the knowledge to pick the right seal class andminimize costly replacements.Two main factors in choosing the right seal are fluid type andtemperature. The chart below is a quick guide to which class ofseal to use in your application:*EPR seals are not compatible with hydraulic oil**Fluorocarbon Seals are not suitable for use with Skydrol fluid, but can be used with hydraulic oil if desired.HY08-4100-B1/NA April 2020© 2020 Parker Hannifin Corporation。
