The AA10VO60DFR/52R-VSC62N00 pump belongs to the A10VSO Variable Pumps series manufactured by Bosch Rexroth for open-circuit hydraulic systems. It uses DFR pressure-flow control, so both displacement and outlet pressure are regulated automatically to stabilize actuator speed. Continuous duty is supported by a nominal pressure of 280 bar, while temporary load spikes are handled up to a peak pressure of 350 bar. The case can withstand an absolute internal pressure of 2 bar, and the suction line must not fall below 0.8 bar absolute to prevent cavitation. Clockwise rotation matches typical engine drive arrangements, and the side port orientation specified as version 62 simplifies hose routing in compact power units.
An ISO 3019-1 two-hole flange secures the housing to standard pump pads, and SAE ISO 6162 working ports provide leak-tight high-pressure connections to downstream components. The pilot port is threaded 7/16-20 UNF-2B and tolerates up to 350 bar, while a differential pilot pressure of 14 bar is required for proper control spool movement. No through drive is fitted, so the unit cannot directly power additional pumps in tandem. FKM sealing material resists common hydraulic oils at elevated temperature, and delivered oil cleanliness must meet ISO 4406 20/18/15 to avoid accelerated wear. Overall, these characteristics support reliable variable-flow service where precise pressure control and standard interface geometry are important.
