The AA10VO60DFR/52L-VWC61N00 variable pump belongs to the A10VSO Variable Pumps series and is manufactured by Bosch Rexroth. Designed for hydraulic automation, it adjusts oil flow in open-circuit systems to match actuator demand. A swashplate axial piston layout lets the displacement change continuously, while the integrated DFR pressure/flow controller modulates the angle. The controller holds a differential pressure of 14 bar (200 psi) so auxiliary valves receive a stable supply. System limits are defined by a nominal pressure of 280 bar (4000 psi) and a peak pressure of 350 bar (5100 psi), allowing the pump to cover common industrial pressure ranges. Counter-clockwise rotation aligns with engines or electric motors that turn left-hand. Two case drain ports relieve internal leakage to the reservoir, and SAE J518 flanged ports provide the main connections. Mounting follows the SAE J744 flange pattern for direct coupling to standard power frames.
Rear-facing service ports, identified as version 61 N00, keep hoses clear of the drive train and simplify maintenance from the back of a manifold block. The unit does not include a through drive, coded N00, so it cannot be tandem-mounted and transfers all torque solely to its own rotor group. Pilot port X uses a 7/16-20 UNF-2B threaded cavity to accept pressure signals that shift the swashplate via the DFR mechanism. Fluid retention relies on FKM seals, which withstand high temperature oils and most mineral hydraulic fluids. These construction details allow controlled displacement, defined pressure boundaries, and straightforward installation without auxiliary shafts or non-standard fittings.
