The AA10VO45DR/52L-VSC64N00 pump belongs to the A10VSO Variable Pumps series and is manufactured by Bosch Rexroth. It converts mechanical drive power into regulated hydraulic flow for automation circuits. The geometric displacement is 45 cm³ per revolution, which establishes the fundamental volume moved each shaft turn. When the input shaft runs at 1800 rpm the pump delivers 81 L per minute, while the maximum flow reaches 117 L per minute at the permitted top speed. That top speed is 2600 rpm at full displacement. System limits are defined by a nominal pressure of 280 bar and a peak pressure tolerance of 350 bar for short overload events. Inlet conditions are controlled by an allowed absolute pressure range from 0.8 bar to 30 bar to prevent cavitation and seal damage during suction cycles.
Mechanical and interface features support installation in mobile or stationary power units. The housing weighs 21 kg without fluid. Hydraulic connection on the suction side uses an SAE J518 1 1/2-inch port, while the pressure line exits through an SAE J518 1-inch port. Case drainage is routed through a 7/8-14 UNF-2B threaded port, and the internal circuit accepts an absolute case drain pressure up to 2 bar. Initial filling requires 1.0 L of hydraulic oil to prime the pump before start-up. The rotating group withstands axial forces up to 1500 N and radial forces up to 1500 N transmitted from belt or gear drives, maintaining bearing life under combined loads.
