INTRODUCTION
Thank You for purchasing a Gorman-Rupp Hy-
draulic Submersible Pump. Read this manual
carefully to learn how to safely install and operate
your pump. Failure to do so could result in personal
injury or damage to the pump.
A set of manuals accompanies your pump. Each
set consists of three parts; the Installation/Operation Manual contains essential information on installing and operating the pump. However, since
pump installations are seldom identical, some of
the information only summarizes general recommendations and practices required to inspect, position, and arrange the pump and piping.
The Parts List Manual provides a performance
curve, pump model cross-section drawing, and
parts list for your pump.
The Maintenance and Repair Manual provides
troubleshooting and maintenance instructions required to properly diagnose operational problems,
and to service the pump components.
The pump is a hydraulic motor-driven submersible
model, capable of handling liquids that may be volatile or flammable, and which could cause serious
illness or injury through direct exposure or emitted
fumes.
The pump is designed to be driven only by an
open-center type hydraulic power source with
flows and pressures not exceeding the nominal
specifications shown for your pump in Table 1,
Section B. Do not use closed-center valves or
operate the pump at higher flows or pressures.
Closed-center valves or operation at higher flows
or pressures will damage the pump motor and/or
seal, and void the pump warranty. Consult the
factory for additional information concerning the
appropriate hydraulic power source.
If there are any questions regarding the pump
which are not covered in this manual or in other literature accompanying the unit, please contact
your Gorman-Rupp distributor or the GormanRupp Company:

SAFETY - SECTION A
This information applies to HS and HSV
Series submersible hydraulic motor
driven pumps.
Before attempting to service the hydraulic power source or pump:
1. Familiarize yourself with this manual.
2. Shut down the hydraulic power
source and take precautions to ensure that it will remain inoperative.
3. Allow the hydraulic oil to cool before attempting to disconnect or
service the pump.
OM−03984
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or damage to equipment. Attach adequate lifting equipment only to the lifting device
on the pump. Hydraulic hoses to the
power source must be removed before
lifting. Make certain that all personnel
are clear of the area before lifting.
After the pump has been installed, make
certain that the pump and all piping or
hose connections are tight, properly
supported and secure before operation.
This pump is designed to pump materials that may be volatile or flammable. Do
not attempt to pump any liquids for
which the pump is not designed, or
which may damage the pump or endanger personnel as a result of pump failure. Consult the factory for specific
application data.
This pump is designed to pump materials which could cause serious illness or
injury through direct exposure or
emitted fumes. Wear protective clothing, such as rubber gloves, face mask
and rubber apron, as necessary, before
disconnecting or servicing the pump or
piping.
Do not operate an internal combustion
engine in an explosive atmosphere.
When operating internal combustion
engines in an enclosed area, make certain that exhaust fumes are piped to the
outside. These fumes contain carbon
monoxide, a deadly gas that is colorless, tasteless, and odorless.
Fuel used by internal combustion engines presents an extreme explosion
and fire hazard. Make certain that all
fuel lines are securely connected and
free of leaks. Never refuel a hot or running engine. Avoid overfilling the fuel
tank, and clean up any fuel spills imme-

diately. Always use the correct type of
fuel.
If using a customer-installed power
source, do not use closed-center
valves. Return flow from the hydraulic
motor must be allowed to return directly
to the oil reservoir to enable the pump
impeller to gradually slow to a stop. Closed-center valves will block this flow,
causing damage to the hydraulic motor
and/or the pump seal.
HS AND HSV SERIESOM−03984
Make sure hydraulic hose connections
are fully tightened. Hydraulic hoses are
equipped with check valves in each end to
prevent oil from escaping when
disconnected. Hose connections must be
tight to fully open these check valves.
Failure to tighten connections can cause
excessive hydraulic system pressure,
resulting in damage to the hydraulic motor
and/or other components.

Review all SAFETY information in Section A.
This section is intended only to summarize recommended installation practices for the pump. If there
are any questions concerning your specific application, contact your Gorman-Rupp distributor or
the Gorman-Rupp Company.
PREINSTALLATION INSPECTION
The pump was inspected and tested before shipment. Before installation, inspect the pump for
damage which may have occurred during shipment. Check as follows:
a. Inspect the pump assembly for cracks, dents,
damaged threads on the hydraulic connecting hoses, and other obvious damage.
b. Check for and tighten loose attaching hard-
ware. Since gaskets tend to shrink after drying, check for loose hardware at mating surfaces.
c. If the pump was shipped with hydraulic
hoses, inspect the hoses for cuts or damage
to the threaded ends.
not put the pump into service until appropriate action has been taken.
Lubrication
The pump was fully lubricated when shipped from
the factory. However, always check the lubricant
level before installing the pump (see LUBRICA-
TION in MAINTENANCE AND REPAIR).
PUMP INSTALLATION
Pump and Power Source Specifications
The Gorman-Rupp Company manufactures a hydraulic power unit specifically designed to power
the hydraulic pump. Only open-center valves
may be used in a customer-supplied power
source, with flows and pressures not exceeding
the nominal specifications shown for your pump in
Table 1. Do not use closed-center valves, or op-
erate the pump at higher flows or pressures.
Closed-center valves or operation at higher flows
or pressures will damage the pump motor and/or
seal, and void the pump warranty.
d. Check the pump hydraulic motor for any oil
leaks, and tighten any hardware as required.
e. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties
as indicated.
f. Check that the hydraulic power source pro-
vides the required horsepower and flow to
properly and safely operate the pump (see
Table 1).
If anything on the pump appears to be abnormal,
contact your Gorman-Rupp distributor or the factory to determine the repair or updating policy. Do
Do not use closed-center valves. Return
flow from the hydraulic motor must be
allowed to return directly to the oil reservoir to enable the pump impeller to
gradually slow to a stop. Closed-center
valves will block this flow, causing damage to the hydraulic motor and/or the
pump seal.
See Figure 1 for a typical hydraulic schematic for a
customer-supplied power source. Consult the factory for additional information concerning the appropriate hydraulic power source.

Make sure hydraulic hose connections
are fully tightened. Hydraulic hoses are
equipped with check valves in each end.
Hose connections must be tight to fully
open these check valves. Failure to tighten
connections can cause excessive hydraulic pressure, resulting in damage to the hydraulic motor and/or other components.
Do not attempt to lift the pump by the hydraulic hoses or the piping. Attach proper
lifting equipment to the lifting device fitted
to the pump. If chains or cable are
wrapped around the pump to lift it, make
certain that they are positioned so as not to
damage the pump, and so that the load will
be balanced.
Hydraulic Power Source Connections
The hydraulic connections on the hoses supplied
with the pump are male and female. The threads
on these hoses must be kept clean and protected.
Be sure hydraulic hoses and connections are
clean before making connections at the pump and
power source. Check connections to be sure they
are tight before starting the power source.
Rotation
Before putting the pump into service, check pump
rotation.
While checking impeller rotation, secure
the pump to prevent rolling.
Suspend the pump by the lifting handle. Quickly
apply power and note the direction of pump kickback. As viewed from the top, the pump should
kickback in a counterclockwise direction (see
Figure 2); this will indicate that impeller rotation is
correct.
If the pump kicks back in a clockwise direction, impeller rotation is incorrect. Consult the Mainte-
nance and Repair manual and make sure pressure is supplied to correct port of the hydraulic motor. Recheck pump kickback; it should now be in a
counterclockwise direction.

Positioning the Pump
NOTE
Refer to OPERATION, Section C and perform a test
on dry land before submerging the pump.
This pump is designed to operate fully or partially
submerged. It may also be operated in air for extended periods.
The pump will operate if positioned on its side, but
this is not recommended because the hydraulic
motor torque could cause the pump to roll during
operation.
The pump should be independently secured and
supported by the lifting device fitted on the pump. If
the application involves a lot of debris, protect the
pump from excessive wear and clogging by suspending it in a perforated barrel or culvert pipe. If

OM−03984HS AND HSV SERIES
which pass through the strainer will pass through
the pump.
Either hose or rigid pipe may be used for discharge piping. To facilitate mobility and maintenance, it is recommended that the discharge line
be fitted with a quick disconnect fitting near the
pump. The discharge line must be independently
supported to avoid strain and vibration on the
pump.
For maximum pumping capacity, keep the discharge as short and straight as possible. Minimize
the use of elbows and fittings which increase friction losses through the discharge piping system.
It is recommended that a check valve or throttling
valve be installed in the discharge line to control siphoning or back flow when the pump is shut off.

OPERATION − SECTION C
Review all SAFETY information in Section A.
The Gorman-Rupp Company manufactures a
hydraulic power unit specifically designed to
power the hydraulic pump. A customer-installed power source may be used to operate the
pump; however, since operating procedures
vary with the power source used, the following
instructions apply to operation with a GormanRupp power unit. Consult the factory for specific information using a customer-installed power
source.
Refer to the INSTALLATION section of this manual before startup.
Follow the instructions on all tags, labels and
decals attached to the power source.
motor must be allowed to return directly
to the oil reservoir to enable the pump
impeller to gradually slow to a stop. Closed-center valves will block this flow,
causing damage to the hydraulic motor
and/or the pump seal.
STARTING
1. Position the submersible pump away from personnel for a dry test on land.
2. Refer to the engine operation manual, start the
engine and allow it to warm up for one or two
minutes. (On units equipped with a 45 gallon
[170 liter] hydraulic tank, adjust engine speed
to 1500 RPM after warm up.)
NOTE
If the engine is equipped with a shutdown system,
hold the reset button in until the engine starts and
the engine oil pressure is maintained.
Do not operate an internal combustion
engine in an explosive atmosphere.
When operating internal combustion
engines in an enclosed area, make certain that exhaust fumes are piped to the
outside. These fumes contain carbon
monoxide, a deadly gas that is colorless, tasteless, and odorless.
Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded. Consult the factory or the
power unit specification data sheet for
the maximum continuous operating
speed.
If using a customer-installed power
source, do not use closed-center
valves. Return flow from the hydraulic
3. Turn the hydraulic pressure control valve clockwise until it stops. This energizes the hydraulic
system.
Do not use the hydraulic pressure control
valve to regulate hydraulic pressure; this
valve is on/off only.
4. Check the hydraulic submersible pump to be
sure it is operating.
5. Check all connections and the pump hydraulic
motor for any oil leaks, and correct as required.
Make sure hydraulic hose connections
are fully tightened. Hydraulic hoses are
equipped with check valves in each end to
prevent oil from escaping when
disconnected. Hose connections must be
tight to fully open these check valves.
OPERATION PAGE C − 1
Page 12
OM−03984
HS AND HSV SERIES
Failure to tighten connections can cause
excessive hydraulic system pressure,
resulting in damage to the hydraulic motor
and/or other components.
6. De-energize the hydraulic system. Connect the
discharge hose and install the pump as described in INSTALLATION, Section B. Energize
the hydraulic system again and adjust the engine speed to achieve the desired pump output.
7. If full volume is not required, the engine speed
may be slowed down as necessary to conserve
fuel. Do not increase engine speed once the
factory-set system operating pressure is
achieved.
NOTE
Some pump models are equipped with a vented
screw (see the Parts Identification List in the MAIN-
TENANCE AND REPAIR MANUAL) which is de-
signed to relieve trapped air in the pump casing.
The pump will not operate if this trapped air is not
removed. If the pump does not produce flow, deenergize the hydraulic system, remove the pump
from the wet well or sump, and check to ensure that
the hole in the vented screw is not clogged.
170_F (77_C). If the temperature becomes excessive, shut down the system and allow the oil
to cool. Check for insufficient oil in the reservoir,
kinked hydraulic hoses, inadequate ventilation
of the reservoir or oil cooler, a clogged return
line filter (on models equipped with a 45 gallon
[170 liter] hydraulic tank, the gauge on the filter
will read in the red or above 40 PSI), or the submersible pump may be running dry for extended periods of time.
Low Oil Shutdown
1. The low oil shutdown switch is mounted on the
front of the hydraulic oil reservoir (on units
equipped with emergency shutdown packages). It will shut down the engine in the event
of loss of hydraulic oil to protect against damage to the system.
Oil Cooler
1. If your hydraulic power unit is equipped with an
engine-mounted air/oil cooler to cool the hydraulic oil, be sure the cooling fins are kept
clean so air can circulate freely through it.
System Leaks
OPERATIONAL CHECKS
Hydraulic Oil Level/Temperature
1. Maintain the hydraulic oil level to the top of the
sight glass on the side of the hydraulic reservoir.
2. After initial startup, check the hydraulic oil level
in the reservoir. Filling the hydraulic hoses initially will cause the level to drop.
3. During operation, check to be sure the hydraulic oil operating temperature never exceeds
1. Check all system components regularly for
leaks. When checking the relief valve, check the
control valve and tubing. Replace the valve,
and repair or replace tubing, fittings, oil cooler
or any other components at the first sign of leakage.
STOPPING
1. To stop the pump, de-energize the system (turn
the control valve counter-clockwise).
2. Reduce the engine speed slowly before stopping to prevent possible system damage.
