The AA10VO100DFR1/31R-VUC62K07 pump is built by Bosch Rexroth as part of the A10VSO Variable Pumps series and delivers hydraulic power to automated machinery. Its geometric displacement of 100 cm³ per revolution establishes the volume moved each shaft turn, and a flow of 180 L/min at 1800 rpm is available when the displacement setting is at maximum. A nominal pressure rating of 280 bar limits continuous system load, while a peak pressure capability of 350 bar provides short-term reserve for transients. Power demand reaches 84 kW at 1800 rpm with a 280 bar differential, matching the output of many industrial prime movers. Torque rises from 159 Nm at 100 bar to 445 Nm at 280 bar so drive sizing can follow actual duty. The shaft may run up to 2400 rpm, yet safe speed at full displacement is restricted to 2000 rpm to control inlet flow velocity. Fluid returns through a drain port threaded 1 1/16-12 UNF-2B, allowing standard hose connections.
A DFR1 control differential of 14 bar maintains the swashplate position relative to load pressure to support constant flow characteristics. The suction port measures 2 1/2 in according to ISO 6162-1 so low inlet velocity can be maintained, and pressurized delivery exits the working port sized 1 1/4 in per ISO 6162-2 for compatibility with common manifold blocks. Pilot functions may operate at pressures up to 350 bar, and the pilot port is tapped 7/16-20 UNF-2B to fit standard test fittings or logic valves. A through-drive flange conforming to SAE J744 127-2 (C) lets an additional pump be mounted in tandem without extra supports. These interface and control figures combine to simplify installation, integrate auxiliary circuits, and ensure the pump meets the performance targets stated above.
