The AA10VSO140DR/31R-PKD62K08 is produced by Bosch Rexroth as part of the A10VSO Variable Pumps series and provides regulated hydraulic energy for automated machinery. It displaces 140 cm³ per revolution, so each shaft turn delivers a defined fluid volume to the circuit. The model turns clockwise, an orientation that must match the drive arrangement. It operates at a nominal pressure of 4,000 psi (280 bar) and can withstand peaks up to 5,100 psi (350 bar) during short transients. System load determines drive demand; 164 lb-ft of torque is required at 100 bar and 453 lb-ft at 280 bar, while the shaft tolerates a maximum input torque of 875 lb-ft for heavy start-up or dynamic cycles.
Version 62 places all service ports on the side of the housing for compact installation. The high-pressure outlet uses a SAE J518 1 1/4-inch flange, and the suction inlet is sized to SAE J518 2 1/2-inch to reduce fluid velocity at the pump entrance. A drain connection tapped 1 1/16-12 UN-2B returns case leakage to tank, and a 7/16-20 UNF-2B pilot port supports external control lines. The housing holds 0.79 gal (3.0 L) of oil that must be prefilled for internal lubrication. A through-drive torque capacity of 875 lb-ft enables the unit to transfer full mechanical power to an additional pump mounted in series. Dry mass is 132 lb (60 kg), permitting routine handling with standard lifting fixtures.
