The AEAA10VSO18DR/31R-PKC62N00 pump belongs to the A10VSO Variable Pumps series from Bosch Rexroth and supplies adjustable hydraulic flow to automated equipment. Its geometric displacement is 18 cm³ per revolution, so each shaft turn moves a consistent fluid volume for precise actuator control. At 1800 rpm the pump outputs 8.5 gpm (32 L/min), a rate suited to medium-duty motion tasks, and its rated speed of 3300 rpm gives additional capacity when the machine cycle accelerates. Shaft speed can climb to 3900 rpm when the swashplate is stroked below maximum displacement, extending the usable range during short demand peaks. Continuous operation is supported at a nominal pressure of 4100 psi (280 bar), while the housing tolerates momentary spikes up to 5100 psi (350 bar). The high-pressure line must not fall below 145 psi (10 bar) absolute to keep the control pistons seated, and inlet pressure must stay above 12 psi (0.8 bar) absolute to avoid cavitation.
A 9/16-18 UNF drain port returns leakage oil to tank and prevents internal pressure buildup, and a 7/16-20 UNF pilot port admits control oil for remote pressure regulation. System flow leaves a 3/4-inch SAE J518 pressure flange, while a 1-inch SAE J518 suction flange provides a low-restriction inlet path. Case pressure is limited to 30 psi (2 bar) absolute so the shaft seal maintains its service life. When the swashplate is at full stroke and the shaft turns at rated speed, the pump supplies 15.6 gpm (59 L/min) to drive larger cylinders or motors. Delivering this output at 280 bar requires 59 lb-ft (80 Nm) of input torque, which guides prime-mover sizing. The assembly weighs 28 lb (12.9 kg) without a through drive, allowing straightforward installation on compact power units.
