The AA10VSO100DFLR/31R-PKC62K05 belongs to the A10VSO Variable Pumps series from Bosch Rexroth and serves as a variable-displacement source of hydraulic power in automated machinery. Each rotation moves 100 cm³ of fluid, setting the pump’s basic delivery rate. At 1800 rpm the flow reaches 47.6 gpm, while nominal speed with the swash plate fully stroked delivers 52.8 gpm to downstream actuators. A permitted peak speed of 2400 rpm lets drive motors accelerate quickly during dynamic cycles. Under a 4100 psi load the shaft transmits 328 lb-ft of torque, equating to 111 hp at 1800 rpm and climbing to 125 hp when the unit runs at its nominal rating; these values help size prime movers and cooler capacity. The pump can lift oil from reservoirs situated up to 31.5 in below the inlet, reducing the need for auxiliary charge pumps in most installations.
The hydraulic interfaces are matched to common manifold hardware: the working port is 1 in per ISO 6162-1 and sustains 5100 psi so cylinder circuits can run at full system pressure. Pilot control functions share the same 5100 psi limit and connect through a 7/16-20 UNF-2B threaded port to accommodate standard pressure lines. Inlet design is handled by a 2 in ISO 6162-1 suction port that tolerates up to 145 psi, enabling pressurized tanks or short booster circuits, while a dedicated drain path is restricted to 30 psi to protect internal seals. When the displacement slider is at Vg max, operating speed must stay within 2000 rpm to preserve bearing life and maintain volumetric efficiency. These pressure, thread, and speed constraints guide system designers as they integrate the pump with servo valves, pressure regulators, and closed-loop controllers.
