The AA10VSO100DRG/31R-PKC62K38 pump belongs to the A10VSO Variable Pumps series from Bosch Rexroth and supplies adjustable flow for hydraulic automation circuits. A displacement of 100 cm³ per revolution sets its basic output per shaft turn, while clockwise rotation aligns with right-hand prime movers. A nominal pressure of 280 bar defines the continuous working limit for line components, and a rated speed of 2000 rpm establishes the reference point for performance charts. At 1800 rpm the pump delivers 180 l/min, providing ample flow without approaching maximum speed. Input torque of 159 Nm at 100 bar shows the drive power required under moderate load. Case-drain pressure is restricted to 2 bar to protect shaft seals, and an internal case volume of 0.58 l accommodates thermal expansion of the operating fluid.
The maximum pressure capability is 350 bar, indicating the highest intermittent load the rotating group can tolerate. The unit can run up to 2400 rpm so it handles short-term speed increases in dynamic duty cycles. When operated at 2000 rpm the flow peaks at 200 l/min, meeting elevated actuator demand. Peak torque rises to 445 Nm at 280 bar, guiding the selection of an adequate prime mover for heavy load starts. Pilot fluid consumption is limited to 1.2 gpm, reducing control oil diversion from the main circuit. With a through drive installed the pump weighs 55.4 kg, whereas omitting the through drive lowers weight to 49.5 kg and eases handling. These characteristics allow the pump to support high-pressure, variable-flow tasks in both open-loop and closed-loop hydraulic systems.
