The PVH98QPCRF1S10C145V1931091 pump is produced by Vickers for the PVH and PVE Open-Circuit Piston Pumps series and supplies variable hydraulic flow in automation circuits. It features a maximum displacement of 98.3 cm³ per revolution so the swashplate can deliver high volumetric output when demanded. At its rated maximum speed of 1800 rpm the unit provides 170 L/min of outlet flow, meeting medium-to-large actuator requirements. System pressure is limited to 250 bar, and a load-sensing pressure compensator adjusts displacement to hold that setting while reducing heat generation. A charge pump integrated on the rear section feeds 17.5 L/min to the inlet gallery to avoid cavitation across the full speed range. Right-hand clockwise rotation matches common engine PTO directions used in mobile machinery.


Mechanical interface details ease installation within standard SAE layouts. An SAE C 4-bolt mounting flange in accordance with J744-127-4 carries the housing load, and pressure lines attach via SAE 4-bolt flange ports that accept high-pressure piping without adapters. Power is transmitted through an SAE C straight-keyed input shaft (J744-32-1); the shaft measures 31.75 mm in diameter and uses a 7.93 mm key to lock against torsional slip. A single one-way shaft seal blocks oil escape along the drive collar and tolerates moderate case pressure. Together these dimensional and sealing features allow direct coupling to electric motors or diesel engines while maintaining low external leakage.
