The AA10VO100DFLR/31LPWC62K01 axial piston unit belongs to the A10VSO Variable Pumps series from Bosch Rexroth and provides adjustable oil flow for hydraulic automation systems. The geometric displacement is 100 cm³ per revolution (6.10 in³/rev), so each shaft turn moves that volume of fluid. The shaft rotates counter-clockwise, matching power-train layouts that use that direction. At 1800 rpm the pump delivers 47.6 gpm (180 L/min), while 2000 rpm raises output to 52.8 gpm (200 L/min) for higher demand circuits. Full-stroke operation is limited to 2000 rpm, and a reduced stroke allows a permitted speed of 2400 rpm for short bursts. The nominal working pressure is 280 bar (4100 psi), and peak events can reach 350 bar (5100 psi) without damaging the housing or rotating group.
The unit develops 328 lb-ft (445 Nm) of torque at 280 bar, so the prime mover must supply that value with margin. Suction conditions must stay above 0.8 bar (12 psi) absolute to avoid cavitation, while case drain pressure must not exceed 2 bar (30 psi) to protect internal seals. An internal case volume of 0.580 gal (2.2 L) stores leakage oil for bearing lubrication and heat removal. Installation uses an ISO 3019-1 two-hole mounting flange, and pressure ports follow the ISO 6162 SAE flange pattern for straightforward pipework. A SAE A 5/8-9T 16/32DP through-drive (code K01) permits tandem mounting of an auxiliary pump. The assembly weighs 122 lb (55.4 kg), which must be supported by the machine frame or gearbox.
