The AA10VO45DFR1/52R-VUC64N00 pump belongs to the A10VSO Variable Pumps series and is manufactured by Bosch Rexroth for closed-loop hydraulic automation. It features a displacement of 45 cm³ per revolution, allowing a fixed volume of fluid to be delivered with each shaft turn. When the shaft runs at 1800 rpm the pump supplies 81 l/min, providing steady flow for medium-capacity circuits, while at its maximum speed of 2600 rpm the flow increases to 117 l/min to meet higher demand. A nominal pressure rating of 280 bar defines the continuous operating limit, and a peak pressure of 350 bar gives short-term overload capability. The permitted top speed of 2600 rpm supports rapid response in variable displacement control. Clockwise rotation matches standard right-hand drive trains, and FKM sealing material resists common hydraulic oils and elevated temperatures to maintain reliability.
The hydraulic interfaces are arranged for straightforward installation: the inlet port follows SAE J518 1 1/2 in for suction lines, the pressure port uses SAE J518 1 in to connect to the system manifold, and a case drain port threaded ISO 11926 7/8-14 UNF-2B returns leakage oil to tank. A pilot port X with a 7/16-20 UNF-2B thread provides control pressure access for external regulators, while a differential pressure setting of 14 bar stabilizes the pump regulator during load changes. Output torque reaches 72 Nm at a 100 bar pressure rise and climbs to 200 Nm at 280 bar, supplying the drive shaft with the necessary mechanical force across its operating range. The bare unit weighs 21 kg, allowing one-person handling during assembly without specialized lifting equipment.
