AA10VSO100DFLR/31R-PKC62K38

The AA10VSO100DFLR/31R-PKC62K38 pump belongs to the A10VSO Variable Pumps series and is produced by Bosch Rexroth. It is intended to supply regulated hydraulic flow in automation circuits where actuator speed needs continuous adjustment. The unit has a displacement of 100 cm³ per revolution so every rotation moves that volume of oil through the system. Clockwise direction of rotation matches common engine drives and simplifies coupling selection. At its nominal speed of 2000 rpm the pump delivers 200 L/min, supporting medium-flow machinery such as plastic molding presses. Power draw at the same speed reaches 93 kW, establishing the drive motor size required. A nominal pressure limit of 280 bar enables consistent operation in closed-loop servo lines, and the pump produces 445 Nm of torque at that pressure, data used to verify shaft and coupling strength. The 1.5000 in shaft diameter provides the mechanical interface for splined or keyed hubs without additional adapters.

For higher duty cycles the pump can be driven up to 2400 rpm before reaching its maximum speed rating, raising output within the variable displacement range. The maximum pressure capability is 350 bar, allowing short overload events without damage. A case drain pressure limit of 2 bar protects the housing seals by keeping internal leakage pressure low. Pilot fluid consumption is capped at 5.5 L/min, which determines the size of the control line feeding the displacement regulator. System plumbing is aided by an SAE J518 2 1/2 in suction port that minimizes inlet velocity, while the SAE J518 1 1/4 in pressure port fits standard high-pressure flanges. Return oil is routed through a 1 1/16-12 UNF-2B drain port so separate leakage flow can be directed to the reservoir. These port, pressure, and speed limits guide installation and ensure reliable hydraulic performance.
