Contact us for current availability
View all specifications

Designed to be cost effective, stable and low-maintenance, the 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.

PVWJ pumps were design and manufactured in such a way that we can offer customers greater flexibility to selectively match pressure and capacity for their specific application.

We offer 3 frame sizes and a total of 10 displacement rates, coupled 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 such as high water content and fire resistant fluids, like Skydrol™, Stack Magic™, Erifon™ and 98/2.

As with all Oilgear pumps, all contact surfaces such as the cylinder surface running on the valve plate and the pistons running on the swashblock surface are all hardened for incredible durability.

Within the PVWJ series, we can offer a displacement range of: 10.8 - 130.2cc/rev. 

Pump Specifications: 
  • Circuit Type: Open loop
  • Fluid Type: Hydraulic, low-lubricity
  • Displacement: 76.5/rev
  • Max Continuous Pressure: 200-250 Bar
  • Max Speed: 3000 RPM
  • Control Response: Medium

The PVWJ range provides a broad range of controls and porting options to take on your most demanding applications. For low to medium horsepower equipment, the PVWJ pumps are uniquely designed for enhanced stability and less maintenance.  Further to that, they’re also a much quieter option for your operations (achieved with the use of static seals (O-rings) to reduce control noise.

Quiet in operation, super high efficiency, compact design, competitive pricing and impressive lead time are the key attributes of the Oilgear PVWJ open loop piston pump. Available in 10 displacement sizes, the PVWJ pumps offer a large selection of readily interchangeable controls. With improved response controls and reduced noise levels, its rugged cylinder design enhances performance.

The patented, pressure lubricated swashblock design offers high performance for high-cycling operations. It also contributes to the pump’s ability to run on low-viscosity fluids, including high water content, fire-resistant and other special fluids.
