The A10VSO100DFLR/31R-PPA12N00 pump belongs to the A10VSO Variable Pumps series from Bosch Rexroth and is intended to regulate flow and pressure in hydraulic automation circuits. Its displacement is 100 cm³ per revolution, establishing the volume delivered each shaft turn. A maximum speed of 2000 rpm permits direct coupling to common prime movers, and the pump can supply up to 52.8 gpm at that speed to feed medium-capacity circuits. Drive sizing is limited by the 125 HP power ceiling, while shaft loading must stay within the 328 lb-ft torque rating. A moment of inertia of 0.396 lb-ft² influences acceleration and deceleration times during duty cycles. System relief can be set as high as 4100 psi by the pressure controller, and the housing tolerates working port pressures up to 5100 psi for continuous service.
The internal case volume of 0.580 gal provides reserve oil for bearing lubrication and heat removal. Fluid temperature may reach 230 °F in operation, and cold starts are permissible with oil viscosity up to 1600 cSt. A 2 1/2 in SAE J518 suction port admits low-velocity inlet flow, while the 1 1/4 in SAE J518 working port delivers pressurized fluid to actuators. Case leakage returns through a 1 1/16-12 UNF-2B drain port, and pilot control signals connect via a 7/16-20 UNF-2B port for remote pressure commands. The pump weighs 109 lb without a through drive, so mounting hardware must support that mass within the chosen hydraulic power unit.
