PVX Series Vane Pumps
Variable Displacement, Pressure Compensated
What Makes PowrFlow PVX Vane Pumps Your Best Buy?
Continental Hydraulics PowrFlow PVX Vane Pumps deliver the
rugged, reliable performance and value you’ve come to
expect in all our products. They outperform sensitive piston
pumps in harsh environments.
PVX Vane Pumps deliver faster response, and require less external
compensation compared to fixed displacement designs.
Here are just a few reasons to choose the PowrFlow line for
3000 PSI Rated at Full Rated Flow on most models
23 to 230 LPM Sizes
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
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.
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
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.

Competitively priced with other manufacturers of vane
and axial piston pumps.
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.
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.
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.
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.
