The PVH131R03AF30B252000001AD100010A piston pump is produced by Vickers for the PVH and PVE Open-Circuit Piston Pumps series and supplies regulated hydraulic flow to automated machinery. The displacement is 131.1 cm³ per revolution, providing 8.0 in³ of fluid with every shaft turn. At the rated speed of 2000 rpm the unit delivers up to 275 L/min, giving high flow capacity for multiple actuators. Rotation is right-hand clockwise so it mates with standard engine drives. An SAE C 4-bolt mounting flange, defined in SAE J744-127-4, aligns the housing with common gearbox faces, while SAE 4-bolt flange ports streamline connection of pressure and return lines. The drive side withstands up to 1215 N·m of input torque to accept high power transmissions. Pump design number 10 identifies this manufacturing revision for parts compatibility.
The pump handles system pressures up to 250 bar, matching the factory pressure setting so no initial field adjustment is required. A compensator pressure control trims the swashplate when the set pressure is reached to reduce energy draw during standby. The built-in load-sensing circuit maintains a 20 bar differential, letting flow rise or fall with downstream demand for stable actuator speed. Control design number 31 specifies the internal spool and spring set that realizes this load-sense logic. A single one-way shaft seal blocks external leakage and allows case pressure to vent toward the suction side, supporting reliable long-term service.
