The AA10VSO45DRG/31R-VUC62N00 pump belongs to the A10VSO Variable Pumps series from Bosch Rexroth and provides adjustable flow for hydraulic automation. A displacement of 45 cm³ per revolution meters oil volume for precise actuator speed control, while clockwise shaft rotation matches standard engine direction to simplify mounting. The nominal pressure rating of 280 bar defines the continuous load that downstream components can withstand. At 1800 rpm the pump supplies 81 L/min, and the related power draw is 38 kW at the same speed and pressure, information used to size prime movers. A torque demand of 72 Nm at 100 bar shows the mechanical load during low-pressure operation. The suction port is 1.5 in (ISO 6162-1), promoting low inlet velocity to reduce cavitation risk, and a bare weight of 23.5 kg facilitates installation on compact power units.
When higher output is required the pump can run at its rated speed of 2600 rpm and is permitted to reach 3100 rpm for brief peaks, extending actuator responsiveness. At rated speed it delivers 117 L/min, and the associated power demand rises to 55 kW at 280 bar, figures used for motor and cooling system selection. The maximum system pressure of 350 bar establishes the upper safety limit for relief valves, while a maximum torque of 200 Nm at 280 bar defines shaft and coupling strength requirements. A 1 in pressure port compliant with ISO 6162-1 standardizes outlet connections. The housing can tolerate 2 bar case drain pressure to protect shaft seals by limiting back pressure.
