The AA10VSO71DR/31R-VKC92K08 pump belongs to the A10VSO Variable Pumps series and is manufactured by Bosch Rexroth for hydraulic automation circuits requiring adjustable flow. Its displacement is 71 cm³ per revolution, enabling precise volume control with each shaft rotation. The pump turns clockwise, making it compatible with engines and electric motors that follow the standard direction. Torque is transmitted through a parallel keyed drive shaft, giving secure mechanical coupling with common hubs. A mounting flange conforming to ISO 3019-1 with two bolt holes simplifies attachment to machine frames. Internal leakage is collected within a 0.420 gallon case volume, helping manage heat and maintaining lubricant circulation. FKM seals are used to withstand elevated temperature and fluid exposure. The unit weighs 78 lb without a through drive, information useful for handling and support bracket design. Working port code 92 identifies the specific port geometry incorporated on this model.
At 1800 rpm the pump supplies 33.8 gpm, offering baseline flow for medium-size actuators. The rated flow rises to 41.2 gpm at the nominal speed, allowing increased circuit throughput when required. Shaft power demand reaches 98 hp at that same reference speed, defining motor sizing for continuous duty. The rotating group tolerates speeds up to 2200 rpm so designers can adjust flow by varying drive speed within this limit. When system pressure is 280 bar the shaft must deliver 233 lb-ft of torque, a value used to check coupling capability. Continuous operation is set at a nominal pressure of 4100 psi, while transient conditions may reach a maximum of 5100 psi. A 7/16-20 UNF-2B threaded port X is provided for case drain or control lines, completing the connection options required for reliable circuit integration.
