The PVH98QICRAF13S10CM731 pump is manufactured by Vickers in the PVH and PVE Open-Circuit Piston Pumps series. This variable displacement axial piston unit supplies hydraulic actuators with pressurized fluid while allowing automatic flow adjustment to meet system demand. Its displacement is 98.3 cm³ per revolution, so each rotation delivers a fixed volume that determines baseline flow capability. At the rated speed of 1800 rpm the pump outputs 170 L/min, supporting medium-size mobile or industrial circuits. The CM compensator keeps system pressure between 35 and 140 bar and leaves the factory set at 70 bar, enabling ready-to-install control of load pressure. Operating limits extend to 250 bar, permitting use in higher pressure loops without overstressing internal parts. Clockwise rotation matches right-hand prime movers and avoids shaft coupling changes.
Control design number 31 identifies the internal valving and spring configuration selected for this model. Fluid enters and leaves through SAE four-bolt flange ports, simplifying rigid hose connections in standard SAE layouts. The housing attaches to power sources with an SAE C four-bolt mounting flange, and torque is transmitted through an SAE CC straight keyed shaft end, both conforming to J744 dimensions for interchangeability. A single one-way shaft seal prevents external leakage while allowing normal pressure balance across the drive end. If a secondary pump is required, a thru-drive rear mount in the SAE A two-bolt pattern lets an auxiliary unit be stacked without extra adaptors. These mechanical features complete the pump interface package and allow straightforward integration into automated hydraulic machinery.
