The AA4VG125EP3D1/32R-NSF52F001DP variable pump belongs to the AA4VG Variable Pumps series and is produced by Bosch Rexroth for closed-loop hydraulic automation. It offers a geometric displacement of 125 cm³ per revolution, which gives a flow of 356 L/min at the nominal speed of 2850 rpm when the swashplate is at maximum stroke. Continuous duty is supported at a nominal pressure of 400 bar, where the drive must supply 796 Nm and can transmit 238 kW of hydraulic power. Short pressure peaks up to 450 bar are permissible, allowing overhead for transient load spikes. Electrical modulation is handled by a 12 V EP3 control circuit that suits mobile machinery power buses.
The pump includes a boost stage with a displacement of 28.3 cm³ that maintains the charge loop at 25 bar to prevent inlet cavitation. During rapid command changes, the rotating assembly withstands an intermittent speed of 3450 rpm and endures angular acceleration up to 14 000 rad/s². Dynamic response is aided by a moment of inertia of 0.0232 kg·m² and a rotary stiffness of 218.3 kNm/rad, keeping shaft deflection low under load. The suction port accepts inlet pressures up to 5 bar absolute, broadening installation options with tank-mounted return filters. For part-load operation the required torque drops to 199 Nm at 100 bar, giving the prime mover headroom in variable-pressure cycles.
