The AEA10VO71DR/31R-PSC92K68-SO13 variable displacement pump belongs to the A10VSO Variable Pumps series and is manufactured by Bosch Rexroth for hydraulic automation where adjustable flow is required. Its geometric displacement is 71 cm³ per revolution (4.33 in³), a value that defines how much fluid is transferred with each shaft rotation. When the pump runs at 1800 rpm with the swashplate set to maximum volume, it delivers 33.8 gpm (128 l/min), supplying standard industrial actuators with a steady flow. The maximum operating speed of 2200 rpm widens the usable range for fast-cycling machinery, and at this speed the pump can move 41.2 gpm (156 l/min) to meet peak demand. A nominal pressure rating of 280 bar (4000 psi) allows continuous operation in high-pressure circuits, while the 350 bar (5100 psi) peak rating provides headroom for short pressure spikes. Flow is directed from port S to port B, which simplifies piping orientation, and a drive-axis moment of inertia of 0.197 lb-ft² (0.0083 kg·m²) minimizes start-up load on the prime mover.
For fluid management and installation, the pump accepts a 2 in SAE J518 inlet port that ensures low inlet velocity, and discharges through a 1 in SAE J518 pressure port to match common manifold blocks. A maximum case drain pressure of 29 psi (2 bar) protects shaft seals by limiting backpressure in the housing, while a filling capacity of 0.42 gal (1.6 l) defines the amount of oil needed to pre-charge the case before start-up. Mechanical interfacing is handled by a SAE J744 101-2 (B) through-drive flange, allowing the unit to mount directly to standard engine or motor housings, and a 7/8 in 13-tooth 16/32 DP through-drive coupler transmits torque to auxiliary pumps without extra adapters. Output torque reaches 83 lb-ft (113 Nm) at 100 bar for light duty cycles and climbs to 230 lb-ft (316 Nm) at 280 bar to drive heavy loads, ensuring consistent power across the pump’s pressure range.
