• Compact Design saves valuable space on your product, or in your power room.
• Pressure Compensation adjusts pump delivery to demand to save energy.
• Fast Response - 20 to 50 ms depending on model.
• Fast Recovery - 70 to 500 ms at minimum flow, depending on model
• 100% Tested
• Quiet Operation
• Three Year Warranty *

The pumps are designed to meet the requirements of the machine tool, general machinery and other markets where low noise, high performance and competitive pricing are needed.

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.

Port 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.

• Shock clipper reduces shock pressure by up to 50%
• Competitively priced with other manufacturers of vane and axial piston pumps.

GENERAL SPECIFICATIONS

 

• DRIVE

Pump to be connected to prime mover by means of a flexible coupling that is aligned to a maximum of .006" (.152 mm) total indicator reading. No overhung or side loads permitted. Alignments greater than .006" (.152 mm) indicator reading could cause increased noise and vibration as well as premature shaft seal wear resulting in leakage.

• FLUID RECOMMENDATIONS

A premium quality hydraulic oil with anti-wear additives is recommended, but not an absolute requirement. Consult factory for use with water base fire resistant fluids.

• FLUID TEMPERATURE

Normal inlet fluid temperature should not exceed 140° F. (60° C.). Always select a fluid for optimum viscosity at operating temperature. Consult factory for applications assistance when inlet fluid temperatures over 140° F. (60° C.) are expected.

• FILTRATION

Fluid cleanliness per ISO/DIS 4406 should be 18/15 or better for pressures of 2000 psi (140 bar) or less. For continuous operating pressures of 2000 to 3000 psi (140 to 210 bar), fluid cleanliness should be 17/13 or better.

Exclusive 3 Year Warranty

Continental Hydraulics Division warrants all Vane & Piston pumps supplied by Continental Hydraulics against defects in material and workmanship under normal use and service for three years from the date of shipment. This warranty does not cover ordinary wear and tear, abuse, misuse, overloading, altered products, use of improper fluid or use of materials not of Continental Hydraulics manufacture or supply.
