PVG-048 Variable Displacement Axial Piston Pump, 48cc/rev

Fast control response with superior performance, the PVG is a variable-displacement axial-piston pump designed to take on all demanding applications. The PVG range offers high-pressure, superior performance in a compact design while thriving on low-viscosity fluids.

Pump Specifications: 

• Circuit Type: Open loop
• Fluid Type: Hydraulic, low-lubricity
• Displacement: 48cc/rev
• Max Continuous Pressure: 301  - 400 Bar
• Max Speed: 2000 - 3000 RPM
• Control Response: Fast

The pumps compact design is made possible with the Oilgear proprietary hydrodynamic bearing that supports the cylinder barrel. With a total of five displacement options from 48cc/rev to 180cc/rev, there’s a high-performance PVG pump avaiable for your specific hydraulic application. 

The PVG open-loop, axial-piston hydraulic pumps provide an almost instantaneous response to system commands through a high-response, four-way, pilot-operated control. Many other pumps this size can’t do that,  especially at this price.

Oilgear has developed 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.
