The AA10VO60DR/52R-VUC61N00 is a variable-displacement axial piston pump in the A10VSO Variable Pumps series manufactured by Bosch Rexroth for hydraulic automation circuits that need adjustable flow. It operates at a nominal pressure of 4000 psi to sustain continuous duty, while a peak rating of 5100 psi accommodates short overload events. Permitted inlet conditions extend from 12 psi absolute to 435 psi absolute, so the suction line can be configured for flooded or mildly pressurized supply tanks. Clockwise rotation must be observed when coupling the pump to a prime mover. A SAE J744 two-hole Type C mounting flange standardizes installation on engines or gearboxes, and an FKM shaft seal contains system fluid under elevated temperature. Pilot oil usage is 0.8 gpm to position the swash plate, and a pressure-control hysteresis of 45 psi keeps outlet pressure fluctuations within a narrow margin during compensator action.
The unit provides two case-drain ports, allowing the return line to be routed on either side of the housing; internal case pressure must remain below 29 psi absolute to protect the seal set. Fluid temperatures can rise to 239 °F without degrading materials, provided viscosity stays within the short-term limits of 60 SUS at the low end and 7500 SUS at the high end. Because there is no through drive, the pump cannot be stacked with an auxiliary pump on the same shaft. These characteristics define the hydraulic boundaries for safe operation and simplify integration into mobile or industrial power units.
