Product Details
That compact design is made possible with our proprietary hydrodynamic bearing that supports the cylinder barrel. And with multiple frame sizes and five displacements, there’s a high-performance PVG made for your operations.
Our PVG open-loop axial-piston hydraulic pumps provide an almost instantaneous response to system commands through a high-response, four-way, pilot-operated control. Other pumps this size can’t do that — especially at our price.
Oilgear has an advanced “hard-on-hard” rotating system that provides longer operational life, resistance to contamination and allows our pumps to thrive on low-viscosity fluids.
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.
