The AA10VO60DFR1/52R-VUD61N00 variable pump is produced by Bosch Rexroth and belongs to the A10VSO Variable Pumps series. It supplies adjustable hydraulic flow for automated actuators while the DFR1 control varies displacement to keep system pressure steady. A nominal pressure limit of 280 bar covers normal duty cycles, and a permitted peak of 350 bar absorbs brief overloads. The load-sensing module holds a differential pressure of 14 bar between pump outlet and control line to maintain consistent flow. Clockwise rotation matches common power-take-off drives found in industrial machines. Installation is simplified by a mounting flange that follows SAE J744 dimensions, and service connections use SAE J518 port flanges for standardized hose interfaces. A pilot port X threaded 7/16-20 UNF-2B accepts external control signals for remote adjustment.
The inlet side operates with absolute pressures from 0.8 bar to 30 bar, enabling both suction feed and booster-assisted supply arrangements. Housing pressure must remain below 2 bar absolute at the case drain to protect the shaft seal. Hydraulic media may enter at viscosities as low as 10 mm²/s during warm operation or as high as 1600 mm²/s during cold starts, and temperatures can rise to 115 °C without impairing function. All service ports are located at the rear in version 61, allowing compact manifold layouts. The unit is supplied without a through drive under option N00, so it cannot mechanically pass power to additional pumps. These inlet limits, temperature ranges, and connection features support precise variable displacement control in hydraulic automation circuits.
