The AA11VLO145DRS/11L-NSD62K02-Y variable pump is produced by Bosch Rexroth within the A11V Variable Pumps series and supplies adaptable hydraulic power to automated machinery. The displacement of 145.0 cm³ per revolution defines how much fluid the unit moves each time the shaft turns. Its DRS pressure and load-sensing control modifies swashplate position to sustain set pressure while trimming flow to match load demand. A nominal speed limit of 2500 rpm lets common electric or diesel drives run the pump without overspeed. When it turns at that speed the pump delivers 363 l/min, giving fast actuator response. A nominal pressure of 350 bar covers continuous duty cycles, and a maximum pressure of 400 bar handles short transients. At 350 bar the working torque reaches 808 Nm, and the shaft can accommodate up to 1640 Nm during start-up or overload events.
The design accommodates tandem arrangements; the through-drive interface passes up to 1110 Nm so a secondary pump can share the prime mover. A rotational inertia of 0.036 kg·m² limits acceleration torque, aiding servo or VFD positioning. The pump must rotate counter-clockwise, aligning with machines that follow the standard L direction. An NBR shaft seal with an FKM lip keeps hydraulic oil contained and resists heat. The suction port is machined with an M16 × 2 thread that accepts widely available fittings. A bare weight of 73 kg calls for mechanical handling during mounting. Power draw reaches 211 kW at the nominal pressure, informing motor selection for full-load operation.
