The PVH074R is manufactured by Vickers and belongs to the PVH and PVE Open-Circuit Piston Pumps series, where it serves as a variable-displacement source of hydraulic flow for automated machinery. Its displacement is 73.7 cm³ per revolution (4.50 in³ per revolution), determining the volume moved each shaft turn. The unit withstands a maximum pressure of 250 bar (3625 psi) so circuits can operate at high working loads. Right-hand, clockwise rotation matches common engine or motor drives without requiring crossover shafts. When supplied in the c version it can run at 2200 rpm; at that speed the pump delivers 136 L/min (36 gpm), giving ample flow for multiple actuators within a single loop.
The compensator factory setting for the c configuration is 25 MPa (250 bar), causing the swashplate to reduce displacement once that pressure is reached, while a secondary cm setting of 7 MPa (70 bar) supports low-pressure standby. A load-sensing differential of 20 bar (290 psi) lets downstream valves maintain stable flow by signaling the pump to adjust output as demand changes. In the qic version the maximum speed is limited to 1800 rpm; at this speed output flow is 125 L/min (33 gpm), balancing lower input power with consistent delivery for mobile or industrial systems that favor quieter operation.
