For 2-pump combinations there is no problem because V series offers 1% thru torque. For 3-pump combinations (and more) the limit torque could be reached or exceeded. Therefore it is necessary to calculate the torque factor and compare it with the allowed torque limit factor in the table. Required: calculated torque factor < torque limit factor To make the necessary calculations easier and more user friendly it is not required to calculate actual torque requirements in Nm and compare them with the shaft limitations. The table on the right shows limit factors that include material specification, safety factors and conversion factors.

ressure Compensators Standard pressure compensator, code F*S The standard pressure compensator adjusts the pump displacement according to the actual need of the system in order to keep the pressure constant. s long as the system pressure at outlet port is lower than the set pressure (set as spring preload of the compensator spring) the working port of the compensator valve is connected to the case drain and the piston area is unloaded. Bias spring and system pressure on the annulus area keep the pump at full displacement. When the system pressure reaches the set pressure the compensator valve spool connects port 1 to and builds up a pressure at the servo piston resulting in a downstroking of the pump. The displacement of the pump is controlled in order to match the flow requirement of the system. Remote pressure compensator, code FRC While at the standard pressure compensator the pressure is set directly at the compensator spring, the setting of the remote pressure compensator can be achieved by any suitable pilot pressure valve connected to pilot port. The pilot flow supply is internal through the valve spool. The pilot flow is 1-1.5 l/min. The pilot valve can be installed remote from the pump in some distance. That allows pressure setting e. g. from the control panel of the machine. The remote pressure compensator typically responds faster and more precisely than the standard pressure compensator and is able to solve instability problems that may occur with a standard pressure compensator in critical applications. The pressure pilot valve can also be electronically controlled (proportional pressure valve) or combined with a directional control valve for low pressure standby operation. 5 Remote pressure compensator, code FR1 Version *FR1 of the remote pressure compensator provides on its top side an interface NG6, DIN 2434 (CETO 3 at R35H, NF D3). This interface allows a direct mounting of a pilot valve (see option *FR and *FRK page 7). Beside manual or electrohydraulic operated valves it is also possible to mount complete multiple pressure circuits directly on the compensator body. arker offers a variety of these compensator accessories ready to install. ll remote pressure compensators have a factory setting of 15 bar differential pressure. With this setting, the controlled pressure at the pump outlet is higher than the pressure controlled by the pilot valve. FR = included FR1 5-5- 23 arker Hannifin Corporation
Load-Sensing Compensators Load-Sensing compensator, code FFC The load-sensing compensator has an external pilot pressure supply. Factory setting for the differential pressure is 1 bar. The input signal to the compensator is the differential pressure at a main stream resistor. load-sensing compensator represents mainly a flow control for the pump output flow, because the compensator keeps the pressure drop at the main stream resistor constant. variable input speed or a varying load(-pressure) has consequently no influence on the output flow of the pump and the speed of the actuator. By adding a pilot orifice (Ø.8 mm) and a pressure pilot valve pressure compensation can be added to the flow control function. See the circuit diagram below, left. Q Load-Sensing compensator code FFC external orifice and pressure pilot valve FF = included FF1 Shown above is load-sensing compensator, code FF1 with an NG6 interface on top of the control valve. That allows direct mounting of a pilot valve for pressure compensation (see option *FF and *FFK page 7). This version includes the pilot orifice. Due to the interaction of flow and pressure compensation this package has not the ideal control characteristic. The deviation is caused by the pilot valves characteristic. If a more accurate pressure compensation is required, the 2-valve load-sensing compensator code FT1 can be used. The circuit diagram of this version is shown left. Here the interaction of the two control functions is avoided by using two separate control valves for flow and pressure compensation. The 2-valve compensator is equipped with an interface NG6 on the compensators top side.

ower Compensators Hydraulic-mechanical power compensator The hydraulic-mechanical power compensator consists of a modified remote pressure compensator ( *L*) or of a modified load-sensing compensator ( *C*) and a pilot valve. This pilot valve is integrated into the pump and is adjusted by a cam sleeve. The cam sleeve has a contour that is designed and machined for the individual displacement and the nominal power setting. t a large displacement the opening pressure (given by the cam sleeve diameter) is lower than at small displacements. This makes the pump compensate along a constant power (torque) curve (see diagrams on opposite page). For all nominal powers of standard electrical motors arker offers a dedicated cam sleeve. The exchange of this cam sleeve (e. g.: to change power setting) can easily be done without disassembly of the pump. On top of that an adjustment of the power setting can be done within certain limits by adjusting the preload of the pilot control cartridge spring. That allows an adjustment of a constant power setting for other than the nominal speeds (15 min -1 ) or for other powers. Ordering code for the power option The first digit designates the power setting: G = 11. kw etc. up to 3 = 132. kw The second digit designates the pilot flow source: L internal pilot pressure, remote pressure function. C external pilot pressure, combines power compensation with load-sensing compensation. The third digit designates the possibility to adjust the overriding pressure compensation: comes with a top side NG6/D3 interface on the control valve to mount any suitable pilot valve or arker pump accessories. B has a threaded pilot port p (G1/4) to connect a remote pilot valve with piping. C includes a pilot valve for manual pressure adjustment. Max. setting: 35 bar. 5 *LC *LB Ø,8 Note: If *CB is connected to an external pilot valve and.8 mm orifice, the orifice in port F has to be removed. *CC *CB 5-5- 25 arker Hannifin Corporation

roportional displacement control, code FV The proportional displacement control allows the adjustment of the pumps output flow with an electrical input signal. The actual displacement of the pump is monitored by an LVDT and compared with the commanded displacement in an electronic control module QDXX. The command is given as an electrical input signal ( - 1 V or resp. 4-2 m) from the supervising machine control. The command can also be provided by a potentiometer. The electronic control module offers a stabilized 1 V source to supply the potentiometer. The electronic module compares permanently the input command and the actual displacement by powering the proportional solenoid of the control valve. deviation from the commanded displacement leads to a modulation of the input current to the solenoid. The control valve then changes the control pressure (port ) until the correct displacement is adjusted. Version FV of the proportional control does not provide a pressure compensation. The hydraulic circuit must be protected by a pressure relief valve. roportional displacement control with overriding pressure control, codes UR, UK and UM Compensator version *UR provides electro- hydraulic displacement control and pressure stage mounted on elbow manifold.
