The AEAA10VSO45DR/31R-PKC62K01 variable displacement pump belongs to the A10VSO Variable Pumps series and is produced by Bosch Rexroth for hydraulic automation. It has a displacement of 45 cm³ per revolution, and with the swashplate at maximum stroke the unit supplies 21.4 gpm at 1800 rpm or 30.9 gpm at 2600 rpm. The maximum speed at full displacement is 2600 rpm, while a permissible peak of 3100 rpm applies when the displacement is reduced. A case volume of 1.0 L stores internal leakage fluid and aids bearing lubrication. Suction oil enters through a 1 1/2 in SAE flange (ISO 6162-1), and inlet pressure must stay below 145 psi (10 bar) to avoid cavitation.
The pump operates at a nominal pressure of 4100 psi (280 bar) and tolerates peaks up to 5100 psi (350 bar). At 2600 rpm and 4100 psi it absorbs 74 HP and produces up to 148 lb-ft of shaft torque. Case drainage is routed through a port limited to 30 psi (2 bar) and threaded 7/8-14 UNF-2B; low back-pressure keeps internal temperature under control. Pilot control oil is connected via a 7/16-20 UNF-2B port, while working flow exits through a 1 in SAE flange (ISO 6162-1). These port sizes and pressure limits simplify integration of the AEAA10VSO45DR/31R-PKC62K01 into hydraulic circuits.
