1 Group 2 Gear Pumps Technical Information

2 Group 2 Family of Gear Pumps SUER-SUNDSTRND High performance gear pumps are fixed displacement pumps which consist of the pump housing, drive gear, driven gear, DU bushings, rear cover and front flange, shaft seal, and inner / outer seals, as shown in the section drawing on page 4. The pressure balanced design of the pumps provides high efficiency for the entire series. The standard SNP 2 pumps are offered throughout the given range of displacements. There are also two special versions, the SHP 2 and the SKP 2. The SHP uses longer journal bearings to achieve a higher pressure capability in the larger displacements. The SKP is designed to accommodate an SE 11 tooth splined shaft for higher torque applications.

11 Definition and Explanation of Technical Terms Maximum speed is the speed limit recommended when operating at rated pressure. It is the highest speed at which normal life can be expected. Minimum Speed is the lower limit of operating speed. It is the lowest speed at which normal bearing life can be expected. It is important to note that the minimum speed increases as operating pressure increases. When operating under higher pressures, a higher minimum speed must be maintained (see graph below). Peak pressure is the highest intermittent pressure allowed, and is determined by the relief valve over shoot (reaction time). Peak pressure is assumed to occur for less than 0 ms in duration. Rated P 2 Pressure P N 1 N 2 Speed Operating Envelope Where: N 1 = Minimum speed at 0 bar N 2 = Minimum speed at 180 bar N 3 = Minimum speed at rated pressure N 3 MX T1 00E System pressure is the differential of pressure between the outlet and inlet ports. It is a dominant operating variable affecting hydraulic unit life. High system pressure, which results from high load, reduces expected life. System pressure must remain at or below rated pressure during normal operation to achieve expected life. Inlet pressure must be controlled in order to achieve expected life and performance. continuous inlet pressure less than those shown in the table below would indicate inadequate inlet design or a restricted inlet screen. Lower inlet pressures during cold start should be expected, but should improve quickly as the fluid warms. Inlet Pressure - bar absolute Recommended Range 0.8 to 3. 0 Minimum (cold start) 0. 6 T1 006E T1 001E Rated pressure is the average, regularly occurring operating pressure that should yield satisfactory product life. It can be determined by the maximum machine load demand. For all systems the load should move below this pressure. 11

12 System Requirements Hydraulic Fluid Ratings and data for Group 2 gear pumps are based on operation with premium hydraulic fluids containing oxidation, rust, and foam inhibitors. These fluids must possess good thermal and hydrolytic stability to prevent wear, erosion, and corrosion of internal components. For more information on fluid selection, see Sauer- Sundstrand publication LN-9887 or For information relating to biodegradable fluids, see Sauer-Sundstrand publication TI-E 91. Never mix hydraulic fluids. These include: Hydraulic fluids per DIN 24, part 2 (HLP) and part 3 (HVLP) PI CD engine oils per SE J183 M2C33F or G automatic transmission fluids Dexron II, IIE, and III meeting llison C3 or Caterpillar TO-2 Certain agricultural tractor fluids Temperature and Viscosity Temperature and viscosity requirements must be concurrently satisfied. The data shown assumes petroleum / mineral based fluids. The high temperature limits apply at the inlet port to the pump. The pump should generally be run at or below the maximum continuous temperature. The peak temperature is based on material properties and should never be exceeded. Cold oil will generally not affect the durability of the pump components, but it may affect the ability to flow oil and transmit power; therefore temperatures should remain 16 C ( F) above the pour point of the hydraulic fluid. The intermittent (minimum) temperature relates to the physical properties of component materials. For maximum unit efficiency and bearing life the fluid viscosity should remain in the recommended viscosity range. The minimum viscosity should be encountered only during brief occasions of maximum ambient temperature and severe duty cycle operation. The maximum viscosity should be encountered only at cold start. During this condition speeds should be limited until the system warms up. Heat exchangers should be sized to keep the fluid within these limits. Testing is recommended to verify that these temperature and viscosity limits are not exceeded. 2 Fluid Viscosity -mm /s (cst) [SUS] M inimum [60] R ecommended Range 12 to 60 [66 to 290] M aximum (cold start) 1600 [700] Temperature - C [ F] M inimum (cold start) - [-4] M aximum Continuous 80 [176] P eak (intermittent) 90 [194] T1 002E T1 003E 12

13 Fluids and Filtration To prevent premature wear, it is imperative that only clean fluid enter the pump and hydraulic circuit. filter capable of controlling the fluid cleanliness to Class 18/13 per ISO 46 or better under normal operating conditions is recommended. The filter may be located on the pump outlet (pressure filtration), inlet (suction filtration), or the reservoir return (return line filtration). The selection of a filter depends on a number of factors including the contaminant ingression rate, the generation of contaminants in the system, the required fluid cleanliness, and the desired maintenance interval. Contaminant ingression rate is determined (among other things) by the type of actuators used in the system. Hydraulic cylinders normally cause higher levels of contamination to enter the system. Fluid Cleanliness Level and b x Ratio Fluid Cleanliness Level (per ISO 46) β x Ratio (Suction Filtration) β x Ratio (Pressure or Return Filtration) Recommended Screen Size Inlet Class 18/13 or better β 7 and -4 = β 0 = β =7 0-1µm 1 2 Filters are selected to meet these requirements using rating parameters of efficiency and capacity. Filter efficiency may be measured with a eta ratio 1 (β X ). For suction filtration, with controlled reservoir ingression, a filter with β -4 = 7 (and β = 2) or better has been found to be satisfactory. For return or pressure filtration, filters with an efficiency of β = 7 are typically required. Since each system is unique, the filtration requirements for that system will be unique and must be determined by test in each case. Filtration system acceptability should be judged by monitoring of prototypes, evaluation of components, and performance throughout the test program. See Sauer-Sundstrand publications LN-9887 [69781] and TI-E 91 for more information. (1) Filter β ratio is a measure of filter efficiency defined by ISO x 472. It is defined as the ratio of the number of particles greater than a given diameter ( x in microns) upstream of the filter to the number of these particles downstream of the filter. T1 004E Reservoir The function of the reservoir is to provide clean fluid, dissipate heat, remove entrained air, and allow for fluid volume changes associated with fluid expansion and cylinder differential volumes. The reservoir should be designed to accommodate maximum volume changes during all system operating modes and to promote deaeration of the fluid as it passes through the tank. The design should accommodate a fluid dwell time between 60 and 180 seconds to allow entrained air to escape. Minimum reservoir capacity depends on the volume needed to cool the oil, hold the oil from all retracted cylinders, and allow expansion due to temperature changes. Normally, a fluid volume of 1 to 3 times the pump output flow (per minute) is satisfactory. The minimum reservoir capacity is recommended to be 1% of the fluid volume. The suction line should be located above the bottom of the reservoir to take advantage of gravity separation and prevent large foreign particles from entering the line. 0-1 µm screen covering the suction line is recommended. To minimize vacuum at the pump inlet, it is recommended that the pump be located below the lowest expected fluid level. The return line should be positioned to allow discharge below the lowest fluid level, and directed into the interior of the reservoir for maximum dwell and efficient deaeration. baffle (or baffles) between the return line and suction line will promote deaeration and reduce surging of the fluid. 13

14 Line Sizing The choice of piping size and installation should always be consistent with maintaining minimum fluid velocity. This will reduce system noise, pressure drops and overheating, thereby maximizing system life and performance. Inlet piping should be designed to maintain continuous pump inlet pressures above 0.8 bar absolute during normal operation. The inlet line velocity should not exceed 2. m/s [8.2 ft/s]. Pump outlet line velocity should not exceed m/s [16.4 ft/s]. System return lines should be limited to 3 m/s [9.8 ft/s]. Inlet Design Hydraulic oil used in the majority of systems contains about % dissolved air by volume. Under conditions of high inlet vacuum, bubbles are released from the oil. These bubbles collapse when subjected to pressure, which results in cavitation which causes erosion of the adjacent material. ecause of this, the greater the air content within the oil, and the greater the vacuum in the inlet line, the more severe will be the resultant erosion. The main causes of over-aeration are air leaks on the inlet side of the pump, and flow line restrictions. These may include inadequate pipe sizes, sharp bends, or elbow fittings causing a reduction of flow line cross sectional area. Providing pump inlet vacuum and rated speed requirements are maintained, and reservoir size and location are adequate, no cavitation problems should occur. 14

15 Pump Drive With a choice between tapered, splined, or parallel shafts, Sauer-Sundstrand gear pumps are suitable for a wide range of direct and indirect drive applications. Typically these applications use a plug-in, belt, or gear to drive the pump input shaft. Group 2 pumps are designed with bearings that can accept some incidental external radial and thrust loads. However, any amount of external load may reduce the expected bearing life. n outrigger bearing is available to accommodate these loads and is shown on page 34. For in-line drive applications, it is recommended that a three piece coupling be used to minimize radial or thrust shaft loads. Plug-in drives, acceptable only with spline shaft configurations, can impose severe radial loads on the pump shaft when the mating spline is rigidly supported. Increased spline clearance does not alleviate this condition. The use of plug in drives is permissible providing that the concentricity between the mating spline and pilot diameter is within 0.1 mm [.004 in]. The drive should be lubricated by flooding with oil. The allowable radial shaft loads are a function of the load position, the load orientation, and the operating pressure of the hydraulic pump. ll external shaft loads will have an effect on bearing life and may affect pump performance. In applications where external shaft loads cannot be avoided, the impact on the pump can be minimized by optimizing the orientation and magnitude of the load. tapered input shaft is recommended for applications where radial shaft loads are present. Spline shafts are not recommended for belt or gear drive applications. For belt drive applications, a spring loaded belt tension device is recommended to avoid excessive belt tension. Thrust (axial) loads in either direction should be avoided. If continuously applied external radial or thrust loads are known to occur, contact Sauer- Sundstrand for evaluation.

17 Pump Life ll Sauer-Sundstrand gear pumps utilize hydrodynamic journal bearings which have an oil film maintained between the gear / shaft and bearing surfaces at all times. If this oil film is sufficiently sustained through proper system maintenance and operating within recommended limits, long life can be expected. NOTE: type life expectancy number is generally associated with rolling element bearings and does not exist for hydrodynamic bearings. Pump life is defined as the life expectancy of the hydraulic components and is a function of speed, system pressure, and other system parameters such as oil cleanliness. High pressure, which results from high load, reduces expected life in a manner similar to many mechanical assemblies such as engines and gear boxes. When reviewing an application, it is desirable to have projected machine duty cycle data which includes percentages of time at various loads and speeds. Prototype testing programs to verify operating parameters and their impact on life expectancy are strongly recommended prior to finalizing any system design. 17

18 Sound Levels Fluid power systems are inherent generators of noise. s with many high power density devices, noise is an unwanted side affect. However, there are many techniques available to minimize noise from fluid power systems. To apply these methods effectively, it is necessary to understand how the noise is generated and how it reaches the listener. The noise energy can be transmitted away from its source as either fluid borne noise (pressure ripple) or as structure borne noise. Pressure ripple is the result of the number of pumping elements (gear teeth) delivering oil to the outlet and the pump s ability to gradually change the volume of each pumping element from low to high pressure. In addition, the pressure ripple is affected by the compressibility of the oil as each pumping element discharges into the outlet of the pump. Pressure pulsations will travel along the hydraulic lines at the speed of sound (about 10m/s in oil) until affected by a change in the system such as an elbow fitting. Thus the pressure pulsation amplitude varies with overall line length and position. Structure borne noise may be transmitted wherever the pump casing is connected to the rest of the system. The manner in which one circuit component responds to excitation will depend on its size, form, and manner in which it is mounted or supported. ecause of this excitation, a system line may actually have a greater noise level than the pump. To reduce this excitation, use flexible hoses in place of steel plumbing. If steel plumbing must be used, clamping of lines is recommended. To minimize other structure borne noise, use flexible (rubber) mounts. The accompanying graph shows typical sound pressure levels for SNP2 pumps (with SE flange, and spline shaft in plug in drive) measured in d() at 1 meter [3.28 ft.] from the unit in a semi-anechoic chamber. nechoic levels can be estimated by subtracting 3 d() from these values.

23 Product Options Shaft Options Group 2 pumps are available with a variety of splined, parallel, and tapered shaft ends. Not all shaft styles are available with all flange styles. Valid combinations and nominal torque ratings are shown in the table below. Torque ratings assume no external radial loading. pplied torque must not exceed these limits regardless of pressure parameters stated earlier. Maximum torque ratings are based on shaft torsional fatigue strength. Recommended mating splines for Group 2 splined output shafts should be in accordance with SE J498 or DIN 482. Sauer-Sundstrand external SE splines are flat root side fit with circular tooth thickness reduced by mm [.00 in] in respect to class 1 fit. The external DIN splines have an offset increased by 0.1 mm [.004 in.] These dimensions are modified in order to assure a clearance fit with the mating spline. Other shaft options may exist.

27 Valve operation and performance The standard priority flow divider valve will supply flow to the priority port (PF) within % of its setting regardless of operating pressure, assuming adequate pump speed (and flow) is attained. ll excess pump flow is directed to the non-priority port (NPF). The priority flow rate is controlled by the combination of priority orifice diameter and spring force C. The spring end of spool sees the pressure downstream of priority orifice and the force of spring C. The non-spring end of the spool sees the pressure upstream of priority orifice. y default, all flow is directed to port PF. s flow at the priority port approaches the desired rate, the delta pressure across orifice increases. This delta pressure is applied to spool. When this delta pressure overcomes the force of spring C, the spool shifts, diverting oil to port NPF. Load pressure at port PF is referenced to the spring end of spool, allowing the system to deliver flow at the desired rate independent of load pressure.

28 The objective of the static load sense priority flow divider valve is to deliver flow on demand to the priority port ( PF ), while compensating for pressure changes in the load. Therefore, the load sense priority flow divider valve does not maintain a constant flow, it maintains a constant pressure between port PF and the load sense port ( LS ) which is connected to the spring end of spool. To perform this function, port LS is connected to a point downstream of an external control valve that serves as a variable orifice. The flow divider valve can vary flow from zero to maximum available flow depending on the delta pressure across the external control valve ( PF-LS). This configuration operates essentially the same as the standard priority flow divider except that the priority orifice is replaced by an external variable flow control valve. To maintain load pressure compensation, the spring end of spool is now referenced to load pressure through the load sense port, which must be connected to a point between the external control valve and the load.

29 The dynamic load sense priority flow divider employs a bleed orifice D which allows a constant leakage of about 1 l/min or typically less, away from the spring end of spool. This orifice is sized to maintain pressure at the spring end of spool sufficient to keep the spool in balance. In the applied circuit, this leakage is metered by an external valve which in effect controls the flow at port PF. When used with close tolerance rotary valving, this system can prevent valve locking due to sudden thermal shock. n additional benefit of this system is that the spool is maintained in a constant metering condition before any signal input is received, thus resulting in a faster response.

30 With the integral priority flow divider, two types of relief valves are available to protect port PF from over-pressurization. The valves will act at a specific pressure setting as seen at port PF. The Full Flow Relief Valve option is a direct acting relief valve which allows flow to bypass from the priority flow port 'PF' to the pump inlet when pressure at PF reaches the setting. This valve is used when fast action is required. NPF CUTION: When the relief valve is operating in bypass condition, rapid heat generation will occur. If this bypass condition is maintained, premature pump failure will result. PF P1 012 P1 00 Priority Flow...PF Non Priority Flow... NPF Inlet... i Pump Output PF NPF i P1 013

31 The Pilot Relief Valve option opens to relieve the pilot pressure from the spring end of spool '' when the setting is reached. This causes the spool to shift and direct all flow to the non-priority port 'NPF'. It is important to note that the pressure setting of the pilot relief valve is not referenced to port 'NPF'. It is also important to note that the pilot relief valve option does not relieve port 'PF', it only redirects pump flow. When the pilot relief valve is operating, flow at port NPF will increase. dditional circuit pressure protection in the NPF line may be required in some applications.

34 Outrigger earing ssembly n Outrigger earing is available for applications with high radial or thrust loads on the shaft. This option is used primarily for applications with high shaft loads such as to belt or chain drives. The design utilizes roller bearings in the front mounting flange. These bearings absorb the radial and thrust loads on the shaft so that the life of the pump is not affected. The use of roller bearings allows life to be described in hours. The graph to the right shows allowable shaft loads for 00 hour life at 00 rpm versus distance from flange face to center of radial load. vailable Configurations C D E F Code Saft / H L M N P R 9 Mounting Flange S Variant Load (lbf) Load (N) Radial Load xial Load SNP2/...CO94 SNP2/...CI96 SNP2/...CO Distance a (mm) Distance a (in.)
