The AEAA10VSO100DR/31R-PKC62N00 variable pump is part of the A10VSO Variable Pumps series from Bosch Rexroth and is intended for closed-loop hydraulic circuits where flow must change with system demand. Its displacement is 100 cm³ per revolution, which defines the volume of fluid transferred with each shaft turn. The shaft is designed for clockwise rotation, so drivetrain layout must match this orientation. When the swashplate is fully angled, safe speed is limited to 2000 rpm, while at reduced displacement it can reach 2400 rpm; these limits protect rotating components from excessive stress. The pump delivers 47.6 gpm at 1800 rpm and 52.8 gpm at 2000 rpm, values used to calculate circuit flow under common motor speeds. Continuous operation is rated for 4100 psi nominal pressure, with intermittent peaks permitted up to 5100 psi to handle transient load spikes during machine cycles.
Maximum torque demand is 328 lb-ft at 280 bar, so the prime mover must supply that value to maintain full output. The suction port follows the SAE J518 2 1/2 in pattern, giving a low-restriction inlet for reservoir connection, while the pressure port uses an SAE J518 1 1/4 in flange to couple to system piping. A 1 1/16-12 UNF-2B drain port allows case leakage to return to tank and prevents excess housing pressure. Control oil can be routed through the 7/16-20 UNF-2B pilot port, letting external logic modify displacement. Nitrile rubber is used for all dynamic seals to ensure compatibility with standard mineral hydraulic fluids and moderate temperature ranges. The pump weighs 109 lb without a through drive, a factor considered when selecting mounting brackets or service handling equipment.
