The PVH98QICRAF3S10CM731 pump is manufactured by Vickers and belongs to the PVH and PVE Open-Circuit Piston Pumps series. It is a variable displacement axial piston unit intended for hydraulic automation where flow must match load demand. The quiet industrial application design reduces noise in factory environments. A maximum displacement of 98.3 cm³ per revolution lets the pump move substantial volume each stroke. When operated at its rated speed of 1800 rpm, it supplies a nominal flow of 170 L/min. Right-hand clockwise rotation aligns with common engine drives. Power transfers through an SAE CC 17-tooth spline shaft, and a single one-way shaft seal limits leakage along that interface. The housing secures to equipment with an SAE C 4-bolt mounting flange.
System pressure capacity reaches 250 bar, while the factory pressure setting is limited to 70 bar to simplify commissioning. A compensator pressure control (code CM) modulates the swashplate to maintain the chosen outlet pressure. Main hydraulic lines connect via SAE 4-bolt flange ports that handle high operating pressures. A thru-drive rear mount in SAE A 2-bolt form enables tandem installation of an auxiliary pump. Design number 10 marks the mechanical revision, and control design number 31 specifies the associated compensator tuning. These attributes allow the pump to fit open-circuit power units that require compact size, steady flow, and automatic pressure regulation under variable load conditions.
