The AA10VSO10DFR/52R-PUC64N00 is produced by Bosch Rexroth for the A10VSO Variable Pumps series and supplies controlled hydraulic power for automation equipment. It is configured for an open circuit, so it fits supply-and-return systems that use an external reservoir. DFR pressure-flow control adjusts output in response to changing load conditions. A displacement of 10.5 cm³ per revolution defines the volume moved by each shaft turn, while clockwise rotation aligns the drive with right-hand prime movers. The pump can run up to 3600 rpm, which establishes its mechanical speed ceiling. An ISO 3019-1 two-hole mounting flange provides a straightforward interface to SAE pattern housings, and the N00 through-drive code shows that no secondary pump can be piggy-backed.
When operated at 1800 rpm the unit supplies 18.9 l/min, and flow increases to 37 l/min at 3600 rpm for applications that need higher actuator speed. A nominal pressure of 250 bar marks the continuous working limit, while a maximum pressure of 315 bar permits brief overloads. The differential pressure setting is 14 bar, influencing the compensator’s transition between flow and pressure control. Minimum displacement can be reduced to 0 cm³ per revolution, allowing standby operation with negligible heat generation.
