The AA10VSO100DFR/31R-PKC62K03 pump belongs to the A10VSO Variable Pumps series and is produced by Bosch Rexroth. It supplies adjustable hydraulic flow for automated machinery and uses DFR pressure-flow control to maintain set pressure while matching delivery to load demands. A displacement of 100 cm³ per revolution establishes the basic volume moved each shaft turn. When driven at 1800 rpm the pump outputs 180 L/min, and at the nominal speed of 2000 rpm the flow reaches 200 L/min. The unit is designed for a nominal pressure of 280 bar, providing stable force for cylinders and motors. Clockwise rotation aligns with common prime movers, and the pump weighs 109 lb without a through drive for manageable handling during assembly.
For overload events the maximum pressure rating rises to 350 bar, and the pump tolerates a peak speed of 2400 rpm when operated below maximum displacement. Output torque is 159 Nm at 100 bar and increases to 445 Nm at 280 bar, values that guide coupling and shaft sizing. The suction port follows ISO 6162-1 with a 2 1/2 in connection, while the pressure port is ISO 6162-2 at 1 1/4 in to standardize high-pressure plumbing. Case drainage is provided through an ISO 11926 1 1/16-12 UNF port, and pilot signaling is routed through an ISO 11926 7/16-20 UNF port. These interfaces integrate the pump into hydraulic circuits that rely on reliable pressure regulation and responsive flow control.
