The AA10VG45HW1/10R-NSC60F043D pump is part of the A10VG Variable Piston Pumps series produced by Bosch Rexroth for closed-loop hydrostatic drives in mobile hydraulic automation. It offers a geometric displacement of 46 cm³ per revolution, and an internal boost stage adds 8.6 cm³ to maintain charge pressure. Continuous operation is possible from 500 rpm up to 3300 rpm, with a limited speed rating of 3550 rpm for short periods. The unit is designed for a nominal pressure of 300 bar and can withstand peak events of 350 bar. The housing contains 0.75 L of oil for internal lubrication and heat removal, and the assembled mass is 27 kg, enabling compact installation inside drive transmissions.
At full displacement the pump delivers 152 L/min, supporting high-demand propel or work circuits. The drive shaft permits 314 Nm of input torque, and the same 314 Nm is authorized for through-drive attachment so a secondary pump can be mounted in series. When system pressure is 100 bar, torque demand falls to 73.2 Nm, whereas at the nominal pressure the requirement increases to 220 Nm. If the machine cycle calls for brief overloads, rotational speed may rise to 3800 rpm on an intermittent basis. Mechanical power draw reaches 75.9 kW at nominal pressure and continuous speed, aligning with mid-size industrial diesel engines. These characteristics allow the unit to provide responsive flow and torque control in variable-speed hydrostatic transmissions.
