The AA10VO45DRG/31L-VSC62N00 pump belongs to the A10VSO Variable Pumps series from Bosch Rexroth and is intended to supply pressurized hydraulic fluid in automated drive circuits. Its displacement is 45 cm³ per revolution, establishing the fixed volume transferred each shaft turn, while a nominal speed of 2600 rpm defines the standard operating point for most installations. Continuous duty is supported by a nominal pressure rating of 280 bar, and at that speed the pump delivers a maximum flow of 117 l/min to maintain actuator motion without flow starvation. A counter-clockwise direction of rotation dictates motor orientation during assembly. The 1 in 15T 16/32DP drive-shaft spline matches common industrial couplings for straightforward power transmission. Fluid enters through a suction port sized to SAE J518 1 1/2 in and exits through a working port specified as SAE J518 1 in, both conforming to widely used flange interfaces. A mass of 23.5 kg influences mounting hardware selection and handling procedures.
The pump can reach a permitted speed of 3100 rpm for short intervals, expanding its flow envelope when required. A maximum pressure capability of 350 bar allows temporary overload without structural damage, and a torque output of 200 Nm at 280 bar defines shaft loading for prime mover sizing. The DRG control maintains a differential pressure of 20 bar to stabilize system response, consuming 1.5 l/min of pilot fluid during operation. Pilot commands are routed through port X threaded 7/16-20 UNF-2B, giving installers a standard connection for remote control valves. Sealing elements are made from FKM, providing resistance to common hydraulic oils and elevated temperatures encountered in industrial machinery.
