The AA10VO60DFR1/52L-VSC62K04 variable pump is produced by Bosch Rexroth and belongs to the A10VSO Variable Pumps series. It regulates hydraulic flow in automated equipment and provides a displacement of 60 cm³ per revolution to match medium flow demands. A differential pressure setting of 200 psi in the DFR1 control trim limits standby pressure without external valves. The inlet side tolerates absolute pressures from 12 psi to a maximum of 435 psi so inlet conditions can vary from low suction to pressurized feeds. Counterclockwise rotation is specified, therefore the drivetrain layout must follow that direction. At nominal speed the unit can supply up to 41.2 gpm, meeting high cycle requirements. A nominal operating pressure rating of 4000 psi supports typical work functions, while the peak pressure limit of 5100 psi covers short transients.
The pump handles case drain pressure up to 29 psi, preventing seal damage when backflow is restricted. An internal case volume of 0.420 gal stores leakage oil and helps temperature stabilization. At 1800 rpm the flow reaches 33.8 gpm, which suits standard electric motor drives. Under that speed and a 4100 psi pressure drop the shaft needs 79 HP, aiding motor sizing. The rotating group exhibits a moment of inertia of 0.197 lb-ft², contributing to quick speed changes in servo loops. Torque output spans from 83 lb-ft at a 1450 psi differential to 233 lb-ft at 4100 psi, giving designers clear data for coupling selection. Total mass with a through drive is 84 lb, affecting mounting structures and transport planning.
