Designed to be cost-effective, stable and low-maintenance, PVWJ is a variable-displacement axial-piston pump with a medium control response. Like all Oilgear pumps, it thrives on low-viscosity fluids — and comes in a variety of frame sizes and available displacement rates.

Product Details
With a range of control and porting options, PVWJ can take on your most demanding applications. For low- to medium-horsepower equipment, PVWJ pumps are uniquely designed for enhanced stability and less maintenance. They’re also a quieter option for your operations. Static seals — also known as O-rings — reduce control noise.
PVWJ pumps are built for greater flexibility to selectively match pressure and capacity. That’s because they’re available in three frame sizes and with 10 displacement rates. And, with a variety of optional controls, the PVWJ family of pumps provides easy field interchangeability.
All Oilgear pumps are designed to thrive on low-viscosity fluids — like high water content and fire-resistant fluids, like Skydrol™, Stack Magic™, Erifon™ and 98/2. Learn more here: Fluid Compatibility of Oilgear Pumps.
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.
