The A10VO140DRG/31L-PSD62K02 SO808 pump is produced by Bosch Rexroth as part of the A10VSO Variable Pumps series and supplies controlled hydraulic flow in mobile and industrial automation circuits. The unit displaces 140 cm³ of oil per revolution, and at 1800 rpm it outputs 66.6 gpm to satisfy actuators that need steady volume at common motor speeds. A nominal working limit of 4000 psi supports typical high-pressure loops, while a peak rating of 5100 psi covers short pressure spikes. The pressure port uses an SAE J518 1 1/4-inch flange, and the inlet port is an SAE J518 2 1/2-inch flange to reduce suction losses. DRG control differential pressure is fixed at 290 psi, allowing the regulator to react quickly to load changes. A case-drain thread of 1 1/16-12 UN-2B returns leakage oil to tank without external adapters.
During dynamic duty, the shaft can turn at 2100 rpm when displacement is below maximum and is limited to 1800 rpm at full stroke to protect sliding surfaces. Drive-side inertia is 0.574 lb-ft², easing acceleration calculations for the prime mover. The shaft resists an overhang moment up to 3319 lb-ft, accommodating belt or gear drives without extra bearings. Output torque reaches 164 lb-ft at 1450 psi and rises to 453 lb-ft at 4000 psi, guiding coupling selection. Sustained work at 1800 rpm and 4000 psi requires about 158 horsepower, a key figure for motor sizing. The assembly weighs 132 lb, so suitable lifting gear is required; together these speed, load, and mass limits define the mechanical envelope for dependable hydraulic automation.
