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.

Designed for power and speed, PVV open-loop, axial-piston hydraulic pumps by Oilgear deliver the punch that is required for large, heavy-duty systems.  Utilizing advanced engineering, the PVV pump line delivers up to 560 horsepower – four times the horsepower at approximately one-third the cost of other models.  Computer-optimized for maximum performance, PVV is compact in design and available in several displacements.

PVV pumps offer a large selection of controls that are readily interchangeable.  With improved high-response controls and reduced noise levels, the rugged cylinder design of the PVV pump enhances optimal performance.  The patented design of its pressure lubricated swashblock offers high performance for high-cycling operations, and contributes to the pump’s ability to run on low-viscosity and other special fluids.

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.
