Rugged and tough, PVWC closed-loop, hydrostatic, axial-piston hydraulic pumps by Oilgear offer low horsepower for high-performance applications. Designed around Oilgear's proven rotating group, the PVWC pump combines quiet operation, high efficiency and competitive pricing in a compact design.
PVWC variable displacement pumps feature a large line of controls with several types of mechanical, hydraulic, and electrohydraulic servo valve 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 rance and sensitivity.
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 a hardened swashblock surface.
All Oilgear pumps are designed to thrive on low-viscosity fluids, such as high water content and fire resistant fluids, like Skydrol™, Stack Magic™, Erifon™, and 98/2. Learn more here: Fluid Compatibility of Oilgear Pumps.
