8 Open circuit control strategies LOAD SENSING OPEN CIRCUIT SYSTEM The pump receives fluid directly from the reservoir through the inlet line. A screen in the inlet line protects the pump from large contaminants. The pump outlet feeds a PVG-32 multi-section, load sensing, directional control valve. The PVG valve directs pump flow to the cylinder and gear motor. A heat exchanger cools the fluid returning from the valve. A filter cleans the fluid before it returns to the reservoir. Flow in the circuit determines the speed of the actuators. The position of the PVG valve determines the flow demand. A hydraulic pressure signal (LS signal) communicates demand to the pump control. The pump control monitors the pressure differential between pump outlet and the LS signal, and regulates servo pressure to control the swashplate angle. Swashplate angle determines pump flow. Actuator load determines system pressure. The pump control monitors system pressure and will decrease the swashplate angle to reduce flow if system pressure reaches the PC setting. A system relief valve in the PVG valve acts as a back-up to control system pressure.

9 Open circuit control strategies PRESSURE COMPENSATED CONTROLS Operation The PC control maintains constant system pressure in the hydraulic circuit by varying the output flow of the pump. Used with a closed center control valve, the pump remains in high pressure standby mode at the PC setting with zero flow until the function is actuated. This condition is often called a dead head condition. Typical operating curve Q max Simple closed-center circuit Flow Pressure PC setting P11 166E Once the closed center valve is opened, P the PC control senses the immediate drop in system pressure and increases pump flow by increasing the swashplate angle. The pump continues to increase flow until system pressure reaches the PC setting. If system pressure exceeds the PC setting, the PC control reduces the swashplate angle to maintain system pressure by reducing flow. The PC control continues to monitor system pressure and changes swashplate angle to match the output flow with the work function pressure requirements. If the demand for flow exceeds the capacity of the pump, the PC control directs the pump to maximum displacement. In this condition, actual system pressure depends on the actuator load. For additional system protection, install a relief valve in the pump outlet line. The Features and options section, page 3, includes control schematic diagrams, setting ranges, and response / recovery times for each control available. Response is the time (in milliseconds) for the pump to reach zero displacement when commanded by the control. Recovery is the time (in milliseconds) for the pump to reach full displacement when commanded by the control. Actual times can vary depending on application conditions. Pressure compensated system characteristics Constant pressure and variable flow High pressure standby mode when flow is not needed System flow adjusts to meet system requirements Single pump can provide flow to multiple work functions Quick response to system flow and pressure requirements Typical applications for pressure compensated systems Constant force cylinders (bailers, compactors, refuse trucks) On/off fan drives BLN L676 RevA Jul 24 9

10 Open circuit control strategies REMOTE PRESSURE COMPENSATED CONTROLS The remote PC control is a two-stage control that allows multiple PC settings. Remote PC controls are commonly used in applications requiring low and high pressure PC operation. Typical operating curve Q max Closed center circuit with remote PC Flow Remote PC setting Pressure PC setting P11 969E P The remote PC control uses a pilot line connected to an external hydraulic valve. The external valve changes pressure in the pilot line, causing the PC control to operate at a lower pressure. When the pilot line is vented to reservoir, the pump maintains a low standby pressure of 15 to 2 bar [215 to 3 psi]. When pilot flow is blocked, the pump maintains pressure at the PC setting. An on-off solenoid valve can be used in the pilot line to create a low-pressure standby mode. A proportional solenoid valve, coupled with a microprocessor control, can produce an infinite range of operating pressures. Size the external valve and plumbing for a pilot flow of 3.8 l/min [1 US gal/min]. For additional system protection, install a relief valve in the pump outlet The Features and options section, page 3, includes control schematic diagrams, setting ranges, and response / recovery times for each control available. Response is the time (in milliseconds) for the pump to reach zero displacement when commanded by the control. Recovery is the time (in milliseconds) for the pump to reach full displacement when commanded by the control. Actual times can vary depending on application conditions. Remote pressure compensated system characteristics Constant pressure and variable flow High or low pressure standby mode when flow is not needed System flow adjusts to meet system requirements Single pump can provide flow to multiple work functions Quick response to system flow and pressure requirements Typical applications for remote pressure compensated systems Modulating fan drives Anti-stall control with engine speed feedback Front wheel assist 1 BLN L676 RevA Jul 24

11 Open circuit control strategies LOAD SENSING CONTROLS Operation The LS control matches system requirements for both pressure and flow in the circuit regardless of the working pressure. Used with a closed center control valve, the pump remains in low-pressure standby mode with zero flow until the valve is opened. The LS setting determines standby pressure. Typical operating curve Load sensing circuit Q max Flow Pressure PC setting P11 968E P Most load sensing systems use parallel, closed center, control valves with special porting that allows the highest work function pressure (LS signal) to feed back to the LS control. Margin pressure is the difference between system pressure and the LS signal pressure. The LS control monitors margin pressure to read system demand. A drop in margin pressure means the system needs more flow. A rise in margin pressure tells the LS control to decrease flow. LS control with bleed orifice The load sense signal line requires a bleed orifice to prevent high-pressure lockup of the pump control. Most load-sensing control valves include this orifice. An optional internal bleed orifice is available, if needed. Integral PC function The LS control also performs as a PC control, decreasing pump flow when system pressure reaches the PC setting. The pressure compensating function has priority over the load sensing function. For additional system protection, install a relief valve in the pump outlet line. The Features and options section, page 3, includes control schematic diagrams, setting ranges, and response / recovery times for each control available. Response is the time (in milliseconds) for the pump to reach zero displacement when commanded by the control. Recovery is the time (in milliseconds) for the pump to reach full displacement when commanded by the control. Actual times can vary depending on application conditions.

12 Operating parameters FLUIDS Ratings and performance data for Series 45 products are based on operating with premium hydraulic fluids containing oxidation, rust, and foam inhibitors. These include premium turbine oils, API CD engine oils per SAE J183, M2C33F or G automatic transmission fluids (ATF), Dexron II (ATF) meeting Allison C-3 or Caterpillar T-2 requirements, and certain specialty agricultural tractor fluids. For more information on hydraulic fluid selection, see Sauer-Danfoss publications 52L463 Hydraulic Fluids and Lubricants,, and 52L465 Experience with Biodegradable Hydraulic Fluids,. VISCOSITY Maintain fluid viscosity within the recommended range for maximum efficiency and bearing life. Minimum viscosity should only occur during brief occasions of maximum ambient temperature and severe duty cycle operation. Maximum viscosity should only occur at cold start: Limit speeds until the system warms up. Fluid viscosity limits Condition mm 2 /s (cst) SUS ν min. continuous 9 58 intermittent continuous 11 5 ν max. intermittent (cold start) 1 47 TEMPERATURE Maintain fluid temperature within the limits shown in the table. Minimum temperature relates to the physical properties of the component materials. Cold oil will not affect the durability of the pump components. However, it may affect the ability of the pump to provide Temperature limits Minimum (intermittent, cold start) - 4 C [- 4 F] Continuous 82 C [18 F] Maximum 14 C [22 F] flow and transmit power. Maximum temperature is based on material properties. Don t exceed it. Measure maximum temperature at the hottest point in the system. This is usually the case drain. Ensure fluid temperature and viscosity limits are concurrently satisfied. INLET PRESSURE Maintain inlet pressure within the limits shown in the table. Low inlet pressure (vacuum) may limit maximum pump speed and cause cavitation. Refer to Inlet pressure vs. speed charts for each displacement. Inlet pressure limits Minimum (continuous) Minimum (cold start).8 bar absolute [6.7 in. Hg vac.] (at reduced maximum speed).5 bar absolute [15.1 in. Hg vac.] CASE PRESSURE Maintain case pressure within the limits shown in the table. The housing must always be filled with hydraulic fluid. Case pressure limits Maximum.5 bar [7 psi] above inlet (continuous) Intermittent 2 bar [29 psi] above inlet (cold start) C Caution Operating outside of inlet and case pressure limits will damage the pump. To minimize this risk, use full size inlet and case drain plumbing, and limit line lengths. 12 BLN L676 RevA Jul 24

13 Operating parameters PRESSURE RATINGS The table, Ratings, page 21, gives maximum and continuous pressure ratings for each displacement. Not all displacements within a given frame operate under the same pressure limits. Definitions of the operating pressure limits appear below. System pressure is the differential pressure between the outlet and inlet ports. It is the 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. Continuous working pressure is the average, regularly occurring operating pressure. Operating at or below this pressure should yield satisfactory product life. For all applications, the load should move below this pressure. Maximum (peak) working pressure is the highest intermittent pressure allowed. Maximum machine load should never exceed this pressure. SPEED RATINGS The table, Ratings, page 21, gives minimum, maximum, and rated speeds for each displacement. Not all displacements within a given frame operate under the same speed limits. Definitions of these speed limits appear below. Rated speed is the maximum recommended operating speed at full displacement and 1 bar abs. [ in Hg vac] inlet pressure. Operating at or below this speed should yield satisfactory product life. Maximum speed is the highest recommended operating speed at full power conditions. Operating at or beyond maximum speed requires positive inlet pressure and/or a reduction of pump outlet flow. Refer to Inlet pressure vs. speed charts for each displacement. Minimum speed is the lowest operating speed allowed. Operating below this speed will not yield satisfactory performance. DUTY CYCLE AND PUMP LIFE Knowing the operating conditions of your application is the best way to ensure proper pump selection. With accurate duty cycle information, your Sauer-Danfoss representative can assist in calculating expected pump life. SPEED, FLOW, AND INLET PRESSURE Inlet pressure vs. speed charts for each displacement show the relationship between speed, flow, and inlet pressure for each displacement. Use these charts to ensure your application operates within the prescribed range. The charts define the area of inlet pressures and speeds allowed for a given displacement. Operating at lower displacements allows greater speed or lower inlet pressure.

14 System design parameters INSTALLATION Series 45 pumps may be installed in any position. To optimize inlet conditions, we recommend installing the pump at an elevation below the minimum reservoir fluid level. Design inlet plumbing to maintain inlet pressure within prescribed limits (see Inlet pressure limits, page 12) Fill the pump housing and inlet line with clean fluid during installation. Connect the case drain line to the uppermost drain port (L1 or L2) to keep the housing full during operation. To allow unrestricted flow to the reservoir, use a dedicated drain line. Connect it below the minimum reservoir fluid level and as far away from the reservoir outlet as possible. Use plumbing adequate to maintain case pressure within prescribed limits (see Case pressure limits, page 12). FILTRATION To prevent damage to the pump, including premature wear, fluid entering the pump inlet must be free of contaminants. Series 45 pumps require system filtration capable of maintaining fluid cleanliness at ISO class 22/18/13 or better. Sauer-Danfoss does not recommend suction line filtration. Suction line filtration can cause high inlet vacuum, which limits pump operating speed. Instead we recommend a 125 µm (15 mesh) screen in the reservoir covering the pump inlet. This protects the pump from coarse particle ingestion. Return line filtration is the preferred method for open circuit systems. Consider these factors when selecting a system filter: Cleanliness specifications Contaminant ingression rates Flow capacity Desired maintenance interval Typically, a filter with a beta ratio of β 1 = 1 is adequate. However, because each system is unique, only a thorough testing and evaluation program can fully validate the filtration system. For more information, see Sauer-Danfoss publication 52L467 Design Guidelines for Hydraulic Fluid Cleanliness. RESERVOIR The reservoir provides clean fluid, dissipates heat, and removes entrained air from the hydraulic fluid. It allows for fluid volume changes associated with fluid expansion and cylinder differential volumes. Minimum reservoir capacity depends on the volume needed to perform these functions. Typically, a capacity of one to three times the pump flow (per minute) is satisfactory. Locate the reservoir outlet (suction line) near the bottom, allowing clearance for settling foreign particles. Place the reservoir inlet (return lines) below the lowest expected fluid level, as far away from the outlet as possible. 14 BLN L676 RevA Jul 24

15 System design parameters FLUID VELOCITY Choose piping sizes and configurations sufficient to maintain optimum fluid velocity, and minimize pressure drops. This reduces noise, pressure drops, and overheating. It maximizes system life and performance. Recommended fluid velocities System lines 6 to 9 m/sec [2 to 3 ft/sec] Suction line 1 to 2 m/sec [4 to 6 ft/sec] Case drain 3 to 5 m/sec [1 to 15 ft/sec] Typical guidelines; obey all pressure ratings. Velocity equations SI units Q = flow (l/min) A = area (mm²) Velocity = Q A (m/sec) US units Q = flow (US gal/min) A = area (in²) Velocity =.321 Q A (ft/sec) SHAFT LOADS Series 45 pumps have tapered roller bearings capable of accepting external radial and thrust loads. The external radial shaft load limits are a function of the load position, orientation, and the operating conditions of the pump. The maximum allowable radial load (R e ) is based on the maximum external moment (M e ) and the distance (L) from the mounting flange to the load. Compute radial loads using the formula below. The table, Ratings, page 21, gives maximum external moment (M e ) and thrust load (T in, T out ) limits for each pump frame size and displacement. Radial load formula M e = R e L Shaft load orientation Re L = Distance from mounting flange to point of load M e = Maximum external moment R e = Maximum radial side load 9 Re 27 Re T out T in Re Axis of swashplate rotation L Re 21 Mounting flange P11 8E BEARING LIFE All shaft loads affect bearing life. In applications where external shaft loads can not be avoided, maximize bearing life by orientating the load between the 15 and 21 positions, as shown. We recommend tapered input shafts or clamp-type couplings for applications with radial shaft loads. The table, Ratings, page 21, gives B 1 bearing life for each pump frame size and displacement.

16 System design parameters MOUNTING FLANGE LOADS Adding auxiliary pumps and/or subjecting pumps to high shock loads may overload the pump mounting flange. The table, Ratings, page 21, gives allowable continuous and shock load moments. Applications with loads outside allowable limits require additional pump support. Shock load moment (M S ) is the result of an instantaneous jolt to the system. Continuous load moments (M c ) are generated by the typical vibratory movement of the application. Estimating overhung load moments Use the equations below to estimate the overhung load moments for multiple pump mounting. See Installation drawings, page 38, to find the distance from the mounting flange to the center of gravity. Refer to the table, Features and options, page 21, to find pump weight.

17 System design parameters AUXILIARY MOUNTING PADS Auxiliary mounting pads are available for all radial ported Series 45 pumps. Since the auxiliary pad operates under case pressure, use an O-ring to seal the auxiliary pump mounting flange to the pad. Oil from the main pump case lubricates the drive coupling. All mounting pads meet SAE J744 Specifications. The combination of auxiliary shaft torque and main pump torque must not exceed the maximum pump input shaft rating. The table, Input shafts, page 32, gives input shaft torque ratings for each frame size. Applications subject to severe vibratory or shock loading may require additional support to prevent mounting flange damage. The table, Ratings, page 21, gives allowable continuous and shock load moments for each frame size. The drawing and table below give mating pump dimensions for each size mount.

Ensure that your application respects these limits. Maximum torque ratings are based on shaft strength. Do not exceed them. Maximum torque ratings assume oil-flooded couplings. Coupling arrangements that are not oil-flooded provide a reduced torque rating. Contact your Sauer-Danfoss representative for proper torque ratings if your application involves non oil-flooded couplings. Sauer-Danfoss recommends mating splines adhere to ANSI B92.1-Class 5. Sauer-Danfoss external splines are modified class 5 fillet root side fit. The external major diameter and circular tooth thickness dimensions are reduced to ensure a good clearance fit with the mating spline. The table, Input shafts, page 32, gives full spline dimensions and data. BLN L676 RevA Jul 24 17

18 System design parameters UNDERSTANDING AND MINIMIZING SYSTEM NOISE A table in the Design and specifications section gives sound levels for each displacement. Sound level data are collected at various operating speeds and pressures in a semianechoic chamber. Many factors contribute to the overall noise level of any application. Here is some information to help understand the nature of noise in fluid power systems, and some suggestions to help minimize it. Noise is transmitted in fluid power systems in two ways: as fluid borne noise, and structure borne noise. Fluid-borne noise (pressure ripple or pulsation) is created as pumping elements discharge oil into the pump outlet. It is affected by the compressibility of the oil, and the pump s ability to transition pumping elements from high to low pressure. Pulsations travel through the hydraulic lines at the speed of sound (about 14 m/s [46 ft/sec] in oil) until there is a change (such as an elbow) in the line. Thus, amplitude varies with overall line length and position. Structure born noise is transmitted wherever the pump casing connects to the rest of the system. The way system components respond to excitation depends on their size, form, material, and mounting. System lines and pump mounting can amplify pump noise. Follow these suggestions to help minimize noise in your application: Use flexible hoses. Limit system line length. If possible, optimize system line position to minimize noise. If you must use steel plumbing, clamp the lines. If you add additional support, use rubber mounts. Test for resonants in the operating range, if possible avoid them. 18 BLN L676 RevA Jul 24

20 Design and specifications DESIGN Series 45 Frame J pumps have a single servo piston design with a cradle-type swashplate set in polymer-coated journal bearings. A bias spring and internal forces increase swashplate angle. The servo piston decreases swashplate angle. Nine reciprocating pistons displace fluid from the pump inlet to the pump outlet as the cylinder block rotates on the pump input shaft. The block spring holds the piston slippers to the swashplate via the slipper retainer. The cylinder block rides on a bi-metal valve plate optimized for high volumetric efficiency and low noise. Tapered roller bearings support the input shaft and a viton lip-seal protects against shaft leaks. An adjustable one spool (PC only, not shown) or two spool (LS and PC) control senses system pressure and load pressure (LS controls). The control ports system pressure to the servo piston to control pump output flow.
