Oilgear_Variable_Piston_Pump_PVWH

The original cost-conscious variable pump.

Designed for long-life on low-viscosity fluids, the PVWH comes in 10 different displacements. The legacy PVWH evolved into the current PVWJ pump line.

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.

The legacy PVWH evolved into the current PVWJ pump line.  Oilgear recommends that all PVWH pumps be replaced by their PVWJ equivalents.

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

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