CONTROL OPTIONS
STANDARD PRESSURE COMPENSATED
Delivers only the flow required by the system, while maintaining
the set pressure. This will save horsepower and unnecessary
wear on the system.
Pressure compensation ranges from 200 to 3500 PSI continuous
duty and up to 4000 PSI intermittently.
REMOTE PRESSURE CONTROL: MODEL CODE 7
Includes all the features of the standard pressure compensator
with the added feature of remote control. This option allows
you to adjust or vent the pump control from a remote location
for multiple pressure operations.
LOAD SENSING CONTROL: MODEL CODE 19
Provides constant flow through a given orifice and pressure
that varies with the load requirements. This control maximizes
efficiency and minimizes heat generation.
HORSEPOWER LIMITING CONTROL: MODEL CODE 26
This control is highly recommended where high pressures -
low flows, and high flows - low pressures are needed.

GENERAL SPECIFICATIONS
Fluids for use in the HPV series piston pumps should be petroleum
based and designated by the fluid manufacturer for use in
hydraulic systems. These fluids should contain rust and oxidation
inhibition, anti-wear, anti-foam, and de-aerating agents.
For other fluid types, please contact your Continental Application
Engineer.

Recommended Operating Viscosities
For petroleum based fluids:
- Optimum -- 140 sus (30 Cst.).
- Continuous Minimum -- 60 sus (10 Cst.).
- Continuous Maximum -- 750 sus (160 Cst.).
-
Operating Temperature
The operating temperature should be determined by the viscosity
characteristics of the fluid used. Because high temperatures
degrade seals, reduce the service life of the fluid, and create
hazards, fluid temperatures should not exceed 180° F.
(82° C.) at the case drain.
ISO 16/13.
Return line: To maintain the minimum prescribed cleanliness
levels, a high quality return line filter should be used.
A filter with a 10 micron rating is normally sufficient to
start up a system. Because every system has unique characteristics,
this rating may need to be changed. Periodic testing of fluid
is highly recommended. The data collected from these tests
will tell if the current filter system is maintaining the
cleanliness of the fluid to the ISO 16/13 level.
The maximum inlet pressure is 50 PSI at all speeds.
Unrestricted, however horizontal mounting is preferred.
Pump and motor must be within .003 inches (0.8 mm) TIR (Total
Indicated Run out) for maximum bearing life.
Jaw type with a flexible web is recommended.
Tire and Chain type couplings are not recommended.
All HPV series piston pumps have two case drain ports. It
is only necessary to connect a case drain line to one of these
ports. The other port is provided to fill the case with fluid
on start up. All case drain lines should be as short as possible
with no restrictions or reduction in size. The routing of
the case drain line back to the reservoir must not allow the
fluid in the case to drain back into the reservoir while the
pump is not in use. This line should terminate below the surface
of the fluid in the reservoir. Please refer to Continental
Hydraulics HPV series installation and service literature
for further explanation. Relief Valves System relief valves
are recommended for all applications to protect personnel
and the system from potentially damaging overloads. These
valves should be sized for the maximum flow of the pump and
set approximately 200 psi above the pump compensator setting.
