The AA10VG45EP4D1/10LNSC60F043DP belongs to the A10VG Variable Piston Pumps series from Bosch Rexroth and supplies adjustable hydraulic flow for automated drive circuits. Its maximum displacement of 46 cm³ per revolution sets the volumetric output range, while an internal boost pump displacement of 8.6 cm³ per revolution keeps the case charged and cooled. A minimum shaft speed of 500 rpm preserves bearing lubrication, and a continuous speed limit of 3300 rpm defines the upper boundary for regular duty. The unit operates at a nominal pressure of 300 bar and can tolerate peak events up to 350 bar. A rotating group moment of inertia of 0.0033 kg·m² supports rapid swash-plate position changes, and a filling capacity of 0.75 L indicates the oil volume required before start-up. Displacement is adjusted by a solenoid controlled at 24 V DC within a ±20 % tolerance to match electronic command signals.
The pump weighs 27 kg without a through drive, which simplifies handling during installation. At maximum speed and displacement it delivers a flow of 152 l/min, and it can briefly run at an intermittent speed of 3800 rpm when short high-flow bursts are needed. Power demand reaches 75.9 kW at 300 bar and rated speed, and the shaft must transmit 220 Nm of torque under those same conditions. Hydraulic connections are provided through SAE J518 3/4 in service ports to match common manifold blocks, and the displacement solenoid presents a nominal resistance of 22.7 Ω so drive electronics can size current drivers correctly.
