Product Description

The variable volume, pressure compensated design features of this pump combined with significant advancements in noise reduction make this pump a perfect match for many industrial applications. 

The controls available provide for standard pressure compensation, load sensing, remote pressure control, and horsepower limiting.  These control options permit the machine designer to utilize efficient pump controls that are tailored for the requirements of a hydraulic system.  PVX controls are available in both single stage and two stage designs.  All of the PVX controls exhibit very good response and recovery times and can incorporate a shock clipper that reduces shock pressure by up to 50%.  This feature increases system component life and system stability.

The hydrodynamic journal bearing design is a feature that enhances the quiet operation of this pump, and eliminates the B-10 rating of the unit.  A one piece rotor shaft contributes to this rugged design with minimized deflection when under high system loads. The rotor design allows the designer to easily configure a tandem mount rear drive option that provides the flexibility of driving multiple pumps with a common input shaft.   This eliminates the need for additional prime movers, when multiple pumps are required. 

Porting plates that provide proper timing for the inlet and discharge cycles of the pump, are designed for efficient and quiet operation.  These pressure loaded port plates provide optimum running clearance to the rotor and contribute to high volumetric and overall efficiency.
