The AA10VSO100DFR/31R-PKC62K01 pump belongs to the A10VSO Variable Pumps series from Bosch Rexroth and is intended to regulate flow in hydraulic automation systems. It provides a geometric displacement of 100 cm³ per revolution so circuit designers can size actuators precisely. When the shaft runs at the nominal speed, the pump delivers a flow of 200 L/min to meet medium-duty demand. Maximum speed reaches 2000 rpm at full displacement and can increase to 2400 rpm when the displacement is reduced, allowing higher throughput during transient peaks. The unit turns clockwise, matching common engine drive directions. Safe suction performance requires an absolute inlet pressure of at least 0.8 bar. Continuous operation is set by a nominal pressure of 280 bar, enabling the pump to support standard industrial loads.
A peak pressure limit of 350 bar lets the circuit absorb short overload events without damage. The DFR control maintains a differential pressure of 14 bar across the pump to keep displacement changes stable under varying load. Case drain pressure must stay below 2 bar to protect internal seals. Installation uses an ISO 3019-1 two-hole mounting flange for compatibility with many power units. The suction port is a 2-1/2 in SAE flange per ISO 6162-1, while the working port is a 1-1/4 in SAE flange according to ISO 6162-2, streamlining hose selection. Control lines connect through a 7/16-20 UNF-2B pilot port thread, and a 5/8 in 9-tooth 16/32DP through-drive hub allows an additional pump to be stacked in series.
