A versatile pump with a modular design.

The Oilgear PVM line of variable-displacement, axial-piston pumps is designed to adapt to your most demanding applications. The PVM's modular features give integrators and OEMs the flexibility needed to meet real world challenges.

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.

Virtually indestructible, the modular PVM open-loop, axial-piston hydraulic pumps offer advanced engineering at an affordable price.  Computer-optimized and with multiple controls available, PVM pumps deliver high performance in a compact design.

Available in three frame sizes and twelve displacements, durable PVM pumps feature Oilgear’s advanced “hard-on-hard” rotating system that provides a higher degree of contamination resistance, allows for higher pressure operation, and increases the pump’s lifecycle.

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.
