PVH98CLF2S10C25V31

The PVH98CLF2S10C25V31 piston pump belongs to the PVH and PVE Open-Circuit Piston Pumps series and is produced by Vickers. Designed for hydraulic automation circuits, it delivers 98.3 cm³ per revolution, supporting medium-to-high flow applications where variable displacement is advantageous. The unit tolerates continuous operation up to 250 bar and connects to machinery through an SAE C 4-bolt mounting flange that follows SAE J744-127-4. Power is transmitted through an SAE C 14-tooth splined shaft that aligns with J744-32-4 dimensions, and rotation is fixed to a left-hand, counter-clockwise direction when viewed from the shaft end. A single one-way shaft seal prevents external fluid leakage while maintaining internal pressure integrity.

The pump uses a pressure compensator control, identified in the type code by the letter C, to modulate displacement once the outlet reaches the set value. The factory setting establishes the compensator cut-off at 25 MPa, allowing the system to stabilize without external adjustment during commissioning. Control design number 31 defines the internal hydraulic logic and matches it with current Vickers service parts. A load-sensing differential of 20 bar lets the pump maintain flow with minimal excess pressure, improving efficiency in circuits that employ proportional valves. Fluid is routed through SAE 4-bolt flange main ports that simplify manifold mounting and reduce installation time.
