Oilgear's PVG Pump Features High Performance in a Compact Design
(January 16, 2006; Milwaukee, Wisconsin) The Oilgear Company's PVG open loop pump series offers high pressure and high performance in a compact design. Computer optimized and available in five displacements and multiple frame sizes, the PVG hydraulic pump provides an instantaneous response to system commands through a high response four-way pilot operated control - a first for this size and price of pump.
A main feature of the high performance PVG pump is the latest version of Oilgear's advanced "hard-on-hard" rotating group. This provides a longer operational life, resistance to contamination, and allows for operation with low viscosity or other special fiuids. Steel shoes with a specially designed face for increased fluid retention, run on the hardened swashblock surface delivering superior performance for high-cycle applications.
Unique to some Oilgear pumps is the hydrodynamic bearing support on the cylinder barrel. This allows the cylinder barrel face to run parallel to the valve plate, and eliminates the need for a roller or needle bearing in the valve plate. The use of hydrodynamic bearings also contributes to the pump's compact design by reducing the internal driveshaft diameter and by reducing the mean cylinder barrel diameter.
Other main features for PVG pumps include:
- Rugged cylinder design
- Quiet valve plate, minimizing noise at electric motor speeds
- SAE heavy duty shaft
- Large selection of controls
- Up to 2700 rpm
- Maximum pressure of 5800 psi (400,0 bar)
- Theoretical Maximum Displacements ranging from 2.93 in3/rev (48,0 ml/rev) to 7.94 in3/rev (130,2 ml/rev)
