Product Details
Available in three frame sizes and seven possible displacements, the PVWW can selectively match pressure and capacity while it works. And, with a variety of optional controls, the PVWW family of pumps provides easy field interchangeability.
PVWW open-loop, variable-displacement, axial-piston hydraulic pumps by Oilgear are uniquely designed for low-lubricity, low-viscosity applications, such as pumping water-based, environmentally friendly fluids, such as Skydrol®, Houghto-Safe®, Erifon®, Stack Magic®, Pelagic® and Oceanic®.
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.
