INTRODUCTION
Thank You for purchasing a Gorman-Rupp 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.
This pump is an SE Series, Handy-SubT submersible model, designed to handle dirty water that
does not contain large entrained solids. Do not attempt to pump volatile, flammable or corrosive liquids that may damage the pump. The basic material of construction is aluminum, with a cast iron impeller.
The pump may be operated fully or partially submerged, but should not be operated dry for extended periods. The integral 1/3 H.P. electric motor
may be driven by any standard 12-volt DC vehicle
battery. The pump is not explosion-proof, and
should not be operated in a hazardous atmosphere.
This manual will alert personnel to known procedures which require special attention, to those
which could damage equipment, and to those
which could be dangerous to personnel. However,
this manual cannot possibly anticipate and provide
detailed precautions for every situation that might
occur during maintenance of the unit. Therefore, it
is the responsibility of the owner/maintenance personnel to ensure that only safe, established main-
tenance procedures are used, and that any procedures not addressed in this manual are performed
only after establishing that neither personal safety
nor pump integrity are compromised by such practices.
If there are any questions regarding the pump or
its application which are not covered in this manual or in other literature accompanying this unit,
please contact your Gorman-Rupp distributor, or
the Gorman-Rupp Company:

The following are used to alert maintenance personnel to procedures which require special attention, to those which could damage equipment, and
to those which could be dangerous to personnel:
Immediate hazards which WILL result in
severe personal injury or death. These
instructions describe the procedure required and the injury which will result
from failure to follow the procedure.
Hazards or unsafe practices which
COULD result in severe personal injury
or death. These instructions describe
the procedure required and the injury
which could result from failure to follow
the procedure.
Hazards or unsafe practices which COULD
result in minor personal injury or product
or property damage. These instructions
describe the requirements and the possible damage which could result from failure
to follow the procedure.

SAFETY - SECTION A
This information applies to the SE Series Handy-SubT submersible electric
motor driven pump.
Do not operate this pump where explosive vapors or flammable material exist.
Death or serious injury will result.
Check the National Electric Code
(N.E.C.) and local codes before using.
Before attempting to open or service the
pump:
1. Familiarize yourself with this manual.
2. Switch off the pump and disconnect the power cables from the vehicle battery to ensure that the
pump will remain inoperative.
3. Allow the pump to cool if overheated.
This pump is designed to handle dirty
water that does not contain large entrained solids. It is not designed to
pump volatile, flammable or corrosive
materials. Do not attempt to pump any
liquids which may damage the pump or
endanger personnel as a result of pump
failure.
casing, electrical shock could occur,
causing severe injury or death to personnel.
Always make sure the switch on the
power cables is in the OFF position before connecting the leads to the vehicle
battery. Failure to do so could cause
arcing, resulting in explosion or fire.
Never attempt to alter the length or repair any power cable with a splice. The
pump motor and cable must be completely waterproof. Damage to the pump
or personal injury may result from alterations.
After the pump has been installed, make
certain that the pump and all piping or
hose connections are secure before operation.
Do not attempt to lift the pump by the
power cables, carry handle or piping.
Attach proper lifting equipment to the
lifting eye fitted to the pump.
Do not allow the pump and vehicle to
come into contact when connecting the
power cable to the battery. If the pump
should develop an internal short to the
Obtain the services of a qualified electrician to troubleshoot, test and/or service the electrical components of this

INSTALLATION − SECTION B
OM−06490SE SERIES
Review all SAFETY information in Section A.
Do not operate this pump where explosive vapors or flammable material exist.
Death or serious injury will result.
Check the National Electric Code
(N.E.C.) and local codes before using.
This section only summarizes recommended installation practices for the pump. If there are questions concerning your specific application, contact
your local distributor or the Gorman-Rupp Company.
PREINSTALLATION INSPECTION
The pump was inspected and tested before shipment from the factory. 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, and other obvious damage.
c. The standard pump is furnished with two
30-foot (3 m) long power cables. Inspect the
cables for cuts or damage.
d. Screw the lifting eye (shipped loose) into the
tapped hole in the top of the motor cover until
fully seated, and secure it with the jam nut.
e. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties
as indicated.
If anything appears to be abnormal, contact your
Gorman-Rupp distributor or the factory to determine the repair or updating policy. Do not put the
pump into service until appropriate action has
been taken.
Lubrication
The shaft seal in this pump is lubricated by the medium being pumped. The bearings in this pump
are permanently lubricated for life. No additional lubrication is required.
PUMP INSTALLATION
Pump Dimensions
b. Check for and tighten loose attaching hard-
ware. Since gaskets tend to shrink after drying, check for loose hardware at mating surfaces.
The pump is provided with a suction strainer to prevent large solids from clogging the impeller. See
Figure 1 for the approximate physical dimensions
of the pump.

Lifting
Pump unit weights will vary depending on the
mounting and drive provided. Check the shipping
tag on the unit packaging for the actual weight, and
use lifting equipment with appropriate capacity.
Drain the pump and remove all customer-installed
equipment such as suction and discharge hoses
or piping before attempting to lift existing, installed
units.
Attach a rope or chain to the lifting handle in the top
of the motor cover. Do not lift the unit by the power
cables or the discharge piping. Do not attach lifting
equipment to the carry handle. Customer installed
equipment such as rigid discharge piping must be
removed before attempting to lift.
Positioning the Pump
This pump is designed to operate fully or partially
submerged; however, it should not be operated
dry for extended periods of time.
Extended dry operation will destroy the
seal assembly.
Secure and support the pump by the lifting eye 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 the bottom is heavily sludge-covered, rest the pump on support blocks or suspend
it from a raft or similar device near the surface of the
liquid. See Figure 2 for typical pump installations.
Do not attempt to lift the pump by the
power cables, carry handle or piping.
Attach proper lifting equipment to the
lifting eye fitted to the pump.
PAGE B − 2 INSTALLATION
The pump is provided with a suction strainer to prevent large solids from clogging the impeller. Any
spherical solids which pass through the strainer
will pass through the pump.
