The AA11VLO130LRDS/10L-NSD62N00 variable pump belongs to the A11V Variable Pumps series from Bosch Rexroth and serves adjustable flow tasks in hydraulic automation. Its displacement reaches 130 cm³/rev, so each shaft revolution moves that oil volume when the swash plate is at full stroke. A minimum displacement of 0 cm³/rev lets the controller cut flow to zero for standby operation. At the nominal rotational speed of 2500 rpm the pump delivers 325 l/min, providing high-volume supply to actuators. Continuous duty is limited by a nominal pressure of 350 bar, balancing output force with service life. Shaft loading under those conditions is defined by a torque of 724 Nm, and the prime mover must supply 190 kW to drive the unit at Vg max and 350 bar.
The internal case volume is 2.9 L, giving space for oil that lubricates bearings and cools rotating parts. A mass of 72 kg influences frame design and handling equipment during installation. Dynamic behavior is characterized by a moment of inertia of 0.0337 kg·m², and the pump tolerates angular acceleration up to 10500 rad/s² for rapid swash-plate adjustments. The suction port accepts only 2 bar, so a charge pump must keep inlet pressure below that limit to prevent cavitation. The working port withstands 400 bar, and this value also represents the maximum pressure the housing can endure in transient load peaks.
