Variable Volume Vane Pump
These variable volume vane pumps provide continuously variable
flow and pressure to closely match input horsepower to output
horsepower.
Features and Benefits:
- Field proven direct spring compensators (PVR Series)
for fast response and no fouling from fluid borne contaminants.
- 13-vane PVR Series pumps deliver minimal flow ripple
for quiet operation.
- Heavy-duty, one-piece forged rotor (PVR / PVX Series)
for longer life.
- Hydrodynamic bearings (PVR / PVX Series) eliminate
B-10 ratings.
- Patented “Walking Ring” (PVR Series) for even wear
and long life.
- Pressure balanced port plates (PVR / PVX Series)
contribute to excellent pump efficiency.
PVR Series Vane Pumps
(Click to link to the PVR page)
Designed to be the medium pressure workhorse of the industry,
you will find PVR Series pumps at work in some of the toughest
applications imaginable, as well as some of the cleanest.

PVX Series pumps offer higher-pressure capacity and a wider
selection of control options than the PVR Series. These
features provide greater flexibility in any application
design. |

HPV Variable Volume Axial Piston
Pump
Product Description
Continental Hydraulics’s variable volume and pressure
compensated design simplifies circuit design, and reduces
heat buildup and noise. Four pump control options permit
the designer to choose the most efficient means to power
his hydraulic equipment. Choices include the standard pressure
compensator control, remote pressure control, load sensing
control, and horsepower limiting control.
Efficiently designed porting reduces noise at all pressure
and flow levels for quiet, efficient operation that eliminates
the need for noise shrouds. The rugged, cast iron body is
thicker at stress points which contributes to quiet operation
Brass piston slippers pivot and rotate to equalize wear
while a fluid passage through the slipper reduces loading
and provides lubrication for the piston shoe and wear plate.
Hardened swash plate and trunnion pins provide rugged support
for the piston block and associated rotating group components.
Features and Benefits
- Hardened swash plate for extended trunnion life
- Balanced piston shoes for high efficiency
- Replaceable port plate and wear plate simplify maintenance
- Efficiently designed porting for reduced noise
- Four pump controls offer design flexibility
- Tandem pump options for multiple pump applications
- Maximum volume control is standard for application
versatility
- High speed operation for mobile applications
- Heavy duty cylinder block and body castings provide
long life and reduced noise
- Bolt-in replacement for PV series Denison

Specifications
- Mountings: SAE 2 bolt mountings. SAE ‘A’, SAE’ B’,
and SAE ‘C’
Tandem pump drive capabilities
- Capacities: 6, 10, 15, 20 29 GPM @ 1750 RPM
- Displacements: .88, 1.26, 2.09, 2.62, and 3.78 cubic
inches per revolution
- Pressure Compensation Ranges: 200 to 3500 PSI continuous
duty, up to 4000 PSI intermittent duty
- Recommended Fluids:
- Petroleum based fluids are recommended. Fluids
should be designated by the fluid manufacturer for
use in hydraulic systems. Fluids should contain
inhibitors to prevent rust and oxidation and should
contain anti-wear, anti-foam, and deaerating agents.
For other fluid types, please contact your Continental
Hydraulics representative. (Contact us now)
- Recommended Operating Viscosity
- Petroleum based fluids:
- Optimum – 140 sus (30 Cst.)
- Continuous Minimum – 60 sus (10 Cst.)
- Continuous Maximum – 750 sus (160 Cst.)
- Max cold start up 7500 SUS
- Fluid Cleanliness – ISO 18-16-13 is recommended
- Operating Temperature – Operating temperature is
determined by the viscosity characteristics of the fluid
used. Control operating temperature as needed to assure
that fluid viscosity is within acceptable limits. Because
high temperatures degrade seals, reduce the service
life of the fluid, and create scalding hazards, fluid
temperatures should not exceed 180° F. (82° C.) at the
case drain.
- Mounting Position – Unrestricted. However, horizontal
mounting is preferred.
- Relief valves are recommended for all applications
to help protect personnel and the system from potentially
damaging overloads
Options and Accessories
- Pressure Compensated - Delivers only the flow required
by the system, while maintaining the set pressure. This
reduces horsepower needs and saves unnecessary wear
on the system.
- Remote Pressure Control – Includes all the features
of the standard control, with the added feature of pressure
control from a remote location. This can be accomplished
either manually, or with the utilization of an electronic
proportional pressure control.
- Load Sensing Control – Provides constant flow through
a given orifice and varies pressure with load requirements.
Results in maximum efficiency and minimum heat generation.
- Horsepower Limiting Control – Best choice for high
pressure/low flow and high flow/low pressure systems.
You can adjust the pump to meet your exact system requirements.
Typical Applications
- Mobile equipment
- Marine auxiliary power
- Construction equipment
- Oil field equipment
- Machine tools
- Metal forming and stamping
- Packaging machinery
