The AA10VO60DFR1/52R-VWD61N00 variable displacement pump belongs to the A10VSO Variable Pumps series and is produced by Bosch Rexroth for closed-loop hydraulic automation that demands adaptable flow. It is configured for clockwise rotation, allowing direct coupling to prime movers that share the same shaft direction. The mounting flange follows the SAE J744 pattern, while pressure and suction ports use the SAE J518 flanged interface to match common hose assemblies. Continuous operation is supported up to 4000 psi (280 bar), and the unit can withstand short peaks of 5100 psi (350 bar) during load transients. A DFR1 pressure compensator maintains a 200 psi (14 bar) differential so the swashplate trims displacement automatically when system demand changes.
Pilot functions consume no more than 0.8 gpm (3 L/min), limiting waste heat in the reservoir. The pilot port X uses a 7/16-20 UNF-2B thread, enabling standard tube fittings for the control line. Pressure control hysteresis is capped at 45 psi (3 bar), holding actuator speed steady when loads fluctuate. The case drain port follows ISO 11926, letting the housing return connect to widely available adapters. Service ports are located at the rear in the 61 N00 orientation so hoses can be routed from a single side of the power unit. There is no through drive, identified by code N00, which shortens the assembly and removes the need to seal a secondary output shaft.
