The AA10VSO140DFR1/31R-PKD62K07-S1092 pump belongs to the A10VSO Variable Pumps series and is produced by Bosch Rexroth. It supplies variable axial piston flow for hydraulic automation systems requiring pressure-compensated delivery. The unit is configured with DFR1 control to modulate displacement in response to differential pressure demand. At each revolution the rotating group displaces 140 cm³, equivalent to 8.54 in³, enabling medium-flow circuits. Rotation is specified clockwise to match standard engine or motor drives. Suction oil enters through an SAE J518 2 1/2 in inlet port, while excess case fluid exits a 1 1/16-12 UN-2B drain interface. The housing attaches to power sources via an SAE J744 152-4 (D) mounting flange, and the nominal working pressure is limited to 280 bar to maintain long-term component life.
For short overload events, the pump tolerates system peaks up to 350 bar, and the internal compensator references a differential pressure setting of 200 psi (14 bar) to shift the swashplate. The input shaft K accepts up to 875 lb-ft (1186 Nm) of torque, whereas the through-drive shaft S can transmit 934 lb-ft (1266 Nm) to an additional pump. Power take-off is supported through a 1 1/4 in 14T 12/24 DP spline that mates with an SAE J744 127-2 (C) through-drive flange, allowing tandem mounting. Delivery oil exits at the SAE J518 1 1/4 in pressure port B, and the complete assembly weighs 132 lb (60 kg), facilitating installation with standard lifting equipment.
