The AA11VO95LRDS/10R-NSD62N00 variable pump is produced by Bosch Rexroth within the A11V Variable Pumps series and supplies pressurized fluid for hydraulic automation systems that require adjustable output. It has a geometric displacement of 93.5 cm³/rev, and displacement can be reduced to 0 cm³/rev for standby operation. When running at the rated displacement, the pump reaches a nominal speed of 2350 rpm and delivers 220 l/min to downstream components. Rotation is clockwise to suit standard right-hand drive arrangements. The rotating assembly can accelerate at up to 13000 rad/s², while the highest permissible speed is 2780 rpm for short intervals. A rotor moment of inertia of 0.0173 kg·m² limits torsional load spikes during rapid speed changes.
The unit operates continuously at a nominal pressure of 350 bar and withstands peaks up to 400 bar. At 350 bar it transmits 521 N·m of shaft torque and produces 128 kW when turning at the nominal speed. Internal leakage collects in a 2.1 L case volume that must be routed back to tank. A 3 in suction port built to SAE J518 admits fluid, and a 1 in working port of the same standard conveys the pressurized flow to the circuit. The housing weighs 53 kg without a through-drive, enabling installation on medium-power prime movers without excessive structural reinforcement.
