Oilgear_Axial_Piston_Pump_PVWJ-022

A cost-effective, rugged pump.

The PVWJ is a variable-displacement, axial-piston pump with medium control response. The PVWJ thrives on low viscosity fluids and is available in a variety of control and porting options. It is designed to be cost-effective 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.

PVWJ open loop, axial piston hydraulic pumps by Oilgear are uniquely designed for enhanced stability and less maintenance in low- to medium horsepower applications. Incorporating static seals (o-rings), the PVWJ family of pumps reduces control noise and features a more aesthetic design.

Available in three frame sizes and ten displacements, PVWJ pumps allow for greater flexibility to selectively match pressure and capacity. And, with a variety of optional controls, the PVWJ family of pumps provide easy field interchangeability.

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.
