The PVH131C LF 136 10 C25V 31 pump belongs to the PVH and PVE Open-Circuit Piston Pumps series and is manufactured by Vickers to supply pressurized fluid in hydraulic automation systems. Its displacement of 131.1 cm³ per revolution determines the volume moved each shaft turn. The pump handles a rated pressure of 250 bar (3625 psi) to deliver reliable force to cylinders and motors. A compensator setting fixed at the same 250 bar limits outlet pressure to safeguard circuit components. Rated speed reaches 2000 rpm at zero inlet pressure, allowing direct coupling to high-speed prime movers. When driven at 1800 rpm and 250 bar it provides an effective flow of 223 L/min (59 gpm) for mid-range circuits. Combined pressure compensation and load-sensing control matches output to demand and trims energy use. Left-hand (counter-clockwise) rotation together with a rotating group inertia of 0.0210 N·m·s² reduces startup torque on the drive train.
The unit attaches to control manifolds through an ISO 4401 size 03 interface for standardized valve mounting. Case drain pressure is capped at 0.5 bar (7 psi) to protect the shaft seal and prevent leakage. A load-sense differential of 20 bar maintains the required pressure drop across proportional valves for steady actuator velocity. The load-sense port is threaded .562-18 UNF-2B, while excess case oil exits via a .875-14 UNF-2B drain port to the reservoir. High-pressure flow leaves the pump through an SAE J518C Code 62 four-bolt outlet flange that withstands heavy line loads. Inlet flow enters via an SAE J518C Code 61 four-bolt suction flange sized for low restriction. These connections complement a control scheme based on pressure compensation and load sensing. At 2000 rpm and 250 bar the pump can deliver up to 249 L/min (66 gpm) to meet peak flow requirements.
