The AA10VO60DFR1/52L-VSC61N00 variable pump is manufactured by Bosch Rexroth and belongs to the A10VSO Variable Pumps series. It provides adjustable hydraulic flow for automation tasks that require precise pressure control in open-circuit systems. The unit uses DFR1 control, which modulates displacement and pressure according to load demand. In its depressurized basic position the displacement is set to Vg Max, ensuring immediate full flow at startup. Shaft rotation is counter-clockwise for left-hand drive arrangements. The rear port layout designated 61 N00 places the working and suction openings on the back of the housing, easing line routing in compact manifolds. A through drive is not fitted, noted by the N00 code, so it operates as a single pump. FKM seals withstand high temperature and mineral oil exposure. The compensator operates with a standard differential of 200 psi (14 bar), and controller hysteresis is limited to 45 psi (3 bar) to minimize pressure fluctuation.
The working port can sustain 5100 psi (350 bar), allowing the pump to drive actuators that need high system pressure. The pilot port is also rated for 5100 psi (350 bar), so external control signals can be routed without separate pressure reduction. Maximum control pressure is capped at 4100 psi (280 bar); above this level the displacement feedback piston could be overloaded. Suction inlet pressure must stay below 145 psi (10 bar) to avoid cavitation, while the drain port should not exceed 30 psi (2 bar) to protect the case seals. These pressure limits define the safe operating window and help maintain efficiency and service life within demanding automation cycles.
