The AA10VO71DRG/31R-VSC92K68 is manufactured by Bosch Rexroth within the A10VSO Variable Pumps series and supplies pressurized oil for hydraulic automation that demands adjustable flow. A displacement of 71 cm³ per revolution defines the volume moved each shaft turn, while the nominal speed at full displacement is 2200 rpm, giving designers the main reference point for power calculations. At 1800 rpm the pump outputs 128 l/min, a rate suitable for medium-duty actuators. Suction enters through a 2 in SAE J518 inlet interface that tolerates up to 10 bar, and discharge leaves a 1 in SAE J518 pressure port. The working port endures 350 bar so cylinders receive high operating pressure. A pressure controller adjustable to 280 bar limits system load, and the swashplate shifts when line pressure rises by 8 bar, maintaining stable operation.
The design permits a maximum speed of 2600 rpm at reduced displacement, allowing higher shaft speed without excess power draw. When running at 2200 rpm with the volume setting at maximum, flow reaches 156 l/min to satisfy peak machine cycles. A 127 mm mounting pilot diameter centers the housing during installation, and the through-drive version weighs 38 kg, enabling handling with standard lifting aids. Internal leakage collects in a 1.6 l case that drains through a 7/8-14 UNF-2B port; this connection must not exceed 2 bar to protect shaft seals. These features combine to manage case pressure, thermal balance, and overall reliability in presses, injection molding machines, and mobile equipment.
