PVH131CRCF16S11C25V31

The PVH131CRCF16S11C25V31 pump belongs to the PVH and PVE Open-Circuit Piston Pumps series and is produced by Vickers for hydraulic automation duties where reliable pressure and flow control are required. Its geometric displacement is 131.1 cm³ per revolution (8.0 in³ per revolution), determining the volume of fluid moved each shaft turn. The unit uses a combined pressure-compensator and load-sensing control that continually adjusts the swashplate to match circuit demand. The compensator is factory set to 250 bar (3625 psi), limiting outlet pressure to protect downstream components. A load-sense differential of 20 bar (290 psi) is maintained so the pump reacts promptly to pressure drops while minimizing energy loss. Fluid enters and leaves through SAE 4-bolt flange ports that support high flow rates and simplified manifold mounting.

This pump can operate continuously at 250 bar (3625 psi), allowing it to supply medium-pressure circuits without intermittent cooling or derating. As a variable displacement axial piston design, it varies output flow by altering the angle of the cylinder block relative to the drive shaft. The housing attaches to an SAE C 4-bolt mounting flange conforming to SAE J744-127-4, enabling direct coupling to standard power takeoffs. Drive rotation is right-hand (clockwise when viewed from the shaft end), so installation must align with matching prime movers. A single one-way shaft seal is fitted to block fluid migration along the drive shaft and maintain case pressure integrity.
