A10VSO18DFR1/31R-PUC62N00

The A10VSO18DFR1/31R-PUC62N00 pump belongs to the A10VSO Variable Pumps series manufactured by Bosch Rexroth for hydraulic automation systems that require adjustable flow. Its displacement of 18 cm³ per revolution determines how much fluid is delivered with each shaft turn, allowing proportional output as speed changes. A differential pressure setting of 14 bar maintains a constant pressure drop across the flow-control orifice so actuators receive stable supply. When the drive runs at 1800 rpm with the swashplate at maximum angle, the unit provides 32 L/min, giving dependable volume for medium-duty circuits. The maximum permissible speed of 3900 rpm applies when the displacement is reduced, extending application flexibility for fast-cycling machines. At 1800 rpm the shaft transmits 15 kW, indicating the power input needed for continuous operation under full stroke. A suction port rating of 10 bar prevents inlet collapse during cold-start or high-viscosity conditions, while 30 Nm of torque at 100 bar shows the twisting force required from the prime mover at low system pressure.

At the nominal speed, the pump can deliver 59 L/min so larger consumers can be supplied without oversizing the prime mover. A maximum flow deviation of 0.9 L/min keeps volumetric accuracy tight, which supports precise actuator positioning. The highest allowable speed at full displacement is 3300 rpm, a limit that protects the rotating group from cavitation. A pilot port capacity of 350 bar enables external control valves to modulate the swashplate with high stiffness. When the shaft turns at nominal speed with the swashplate fully stroked, input power rises to 28 kW, defining motor selection for continuous duty. Torque demand reaches 80 Nm at 280 bar, guiding coupling and gearbox sizing when the system operates near relief pressure. Working port B is also rated to 350 bar so downstream components can safely handle peak load forces without additional pressure reduction.
