The AA10VO45DFR1/52R-VSC62N00 variable pump belongs to the A10VSO Variable Pumps series and is manufactured by Bosch Rexroth for hydraulic automation circuits. Its displacement of 45 cm³ per revolution fixes the volume transferred each cycle, and a clockwise rotation direction matches common engine drives. At 1800 rpm the unit delivers 81 L/min, while an SAE J518 1 1/4-inch inlet port accepts standard suction plumbing and an SAE J518 3/4-inch pressure port provides a matched outlet interface. Continuous duty is rated for 280 bar nominal pressure with a 350 bar peak limit to handle short overloads. The rotating group can run up to 2600 rpm at full displacement, allowing compact design without overspeed.
Maximum flow reaches 117 L/min for higher demand circuits, and a permissible speed of 3100 rpm at reduced displacement widens the operating envelope. Drive sizing is guided by a torque requirement of 200 Nm at 280 bar. Side port orientation identified as Version 62 simplifies pipe routing, and a 3/4-16 UNF-2B case drain returns leakage oil to tank with standard fittings. FKM seals resist heat and mineral oil for extended service life. A 1.0 L filling capacity lets the housing be primed before start-up to prevent dry running, and an assembled weight of 21 kg permits manual handling during installation.
