Data Sheet

Oilgear makes some of the longest-lasting, most reliable pumps in the world.

PFWJ 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 PFWJ family of pumps reduces control noise and features a more aesthetic design.

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