MPG-AA10VSO71DR40RF1V

The MPG-AA10VSO71DR40RF1V motor pump belongs to the MPGB-A10VSO Close-Coupled Motor Pumps series and is produced by Bosch Rexroth. It combines a variable-displacement axial piston pump with an integrated electric motor to supply pressurized hydraulic fluid in automated machinery. The unit is built around a displacement of 71.0 cm³ per revolution so each shaft turn delivers a defined oil volume to downstream circuits. A clockwise rotation when viewed from the shaft end aligns with common drive layouts and simplifies coupling to standard motors. Flow reaches 107 l/min at 1500 rpm, supporting medium-size actuation tasks without exceeding typical motor speeds. At this same speed and the nominal pressure the pump draws 50 kW, which enables correct sizing of electrical supply components. The housing mounts through a two-bolt ISO 3019-2 metric flange, allowing direct replacement within standardized frames. FKM seals maintain fluid integrity against high temperatures and aggressive hydraulic oils during continuous duty.

The integrated DR pressure controller automatically adjusts the swashplate to hold the set pressure, keeping output steady at the 280 bar nominal limit. When system demand peaks, the pump can deliver 156 l/min at the nominal speed of 2200 rpm to satisfy rapid actuator cycles. Under these conditions and at the same nominal pressure it requires 73 kW of mechanical power, matching large industrial drive packages. If pressure rises toward the 350 bar maximum, the housing and rotating group are rated to withstand the higher load without deformation. The resulting torque at nominal pressure and full displacement reaches 316 Nm, information used to specify couplings and drive shafts. By modulating displacement the controller also limits heat generation during partial-load operation.
