AA10VNO85DRS/53R-VWC11N00E

The AA10VNO85DRS/53R-VWC11N00E is an axial-piston variable pump from Bosch Rexroth that belongs to the A10VM Variable Motors series. It supports hydraulic automation by adapting its output to system demand. The pump is intended for open circuit operation so return oil is routed directly to the tank. A swashplate mechanism alters piston stroke, giving a maximum displacement of 85 cm³ per revolution when full flow is needed. At this displacement and rated speed it supplies 230 L/min to actuators. Continuous service is permitted at a nominal pressure of 210 bar, which maintains component life while delivering consistent energy to the hydraulic load.

The unit tolerates momentary pressures up to 250 bar without structural damage when the application calls for short bursts of higher force. Stable performance is maintained at rotational speeds as high as 2700 rpm while running at maximum displacement, broadening the usable operating range. Under nominal flow and pressure the hydraulic power output reaches 80 kW, a figure that guides prime mover selection. Shaft torque under these same conditions is 284 Nm, allowing accurate sizing of couplings and drivetrains. These ratings enable the AA10VNO85DRS/53R-VWC11N00E to deliver variable flow and dependable pressure control in mobile or stationary machinery.
