An extremely responsive high-speed pump.

The PVG is a variable-displacement, axial-piston pump with fast control response. The PVG thrives on low viscosity fluids and is available in a variety of control and porting options. It is designed to be a high-performance solution for your demanding applications.

Oilgear makes some of the longest-lasting, most reliable pumps in the world.  Learn more about the proprietary design of the Oilgear variable-displacement, axial-piston pump line.

PVG open loop, axial piston hydraulic pumps by Oilgear offer high-pressure and superior performance in a compact design. PVG pumps provide an almost instantaneous response to system commands through a high-response four-way pilot-operated control – a first for this size and price of pump.

Available in multiple frame sizes and five displacements, high-performance PVG pumps feature Oilgear’s advanced “hard-on-hard” rotating system that provides longer operational life, resistance to contamination, and allows for operation with low-viscosity or other special fluids. And, its unique hydrodynamic bearing support on the cylinder barrel contributes to the pump’s compact design.

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.
