PVWC Series Pump
The Closed-loop Pump for Low-viscosity Fluids.
Rugged and tough, PVWC closed-loop, hydrostatic, axial-piston hydraulic pumps offer low horsepower for high-performance applications. The PVWC pump combines quiet operation, high efficiency and competitive pricing in a compact design. Capable of operating with low-viscosity or other special fluids, and with excellent contamination resistance properties, PVWC pumps feature a hardened cylinder surface running on a hardened valve plate and pistons that run on hardened swashblock surface.
PVWC variable displacement pumps feature a large line of controls with several types or mechanical, hydraulic, and electrohydraulic servo valve controls which permit easy controls which permit easy field interchangeability. With three capacities per single frame size, PVWC pumps allow users to select their required level of capacity and pressure while providing maximum control range and sensitivity.
