AEAA4VSO71DR/10R-PKD63N00E

The AEAA4VSO71DR/10R-PKD63N00E is built by Bosch Rexroth for the A10VSO Variable Pumps series and serves open-circuit hydraulic systems where adjustable flow supports machine actuation. A geometric displacement of 71 cm³ per revolution defines the volume moved each shaft turn and sets the base for flow calculation. The DR pressure controller modulates swashplate angle to maintain selected system pressure, allowing automatic response to load changes. A clockwise direction of rotation matches engines arranged for standard right-hand shafts. Maximum speed at full displacement reaches 2200 rpm, so designers can size prime movers without overspeeding the rotary group. At that limit, the pump supplies up to 156 l/min, giving high delivery for mobile or industrial actuators. A swashplate rotary group design varies piston stroke to adjust flow while keeping compact dimensions.

The unit operates with a nominal pressure of 350 bar and tolerates peaks to 400 bar, providing headroom for transient loads in lifting or steering circuits. Delivered shaft power equals 91 kW at 350 bar, which indicates the engine rating required to drive the pump at full load. Corresponding torque at that pressure is 395 Nm, informing coupling and shaft sizing. The SAE J744 four-bolt mounting flange offers standardized installation on US market machinery, and the same regional alignment is confirmed by the listed SAE version. No through drive is provided, so the pump cannot directly power a secondary unit on its rear face. Because it works exclusively in open circuit mode, external reservoirs and return lines handle fluid cooling and contamination control, simplifying maintenance while meeting typical mobile equipment layouts.
