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-SubTsubmers-
ible model, designed to handle dirty water that
does not contain large entrained solids. Do not at-
tempt to pump volatile, flammable or corrosive liq-
uids that may damage the pump. The basic materi-
al of construction is aluminum, with a cast iron im-
peller.
The pump may be operated fully or partially sub-
merged, but should not be operated dry for ex-
tended 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 atmo-
sphere.
This manual will alert personnel to known proce-
dures 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 per-
sonnel to ensure that only safe, established main-
tenance procedures are used, and that any proce-
dures not addressed in this manual are performed
only after establishing that neither personal safety
nor pump integrity are compromised by such prac-
tices.
If there are any questions regarding the pump or
its application which are not covered in this man-
ual or in other literature accompanying this unit,

SAFETY - SECTION A
This information applies to the SE Se-
ries Handy-SubTsubmersible electric
motor driven pump.
Do not operate this pump where explo-
sive 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 man-
ual.
2. Switch off the pump and discon-
nect the power cables from the ve-
hicle battery to ensure that the
pump will remain inoperative.
3. Allow the pump to cool if over-
heated.
This pump is designed to handle dirty
water that does not contain large en-
trained 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.
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
casing, electrical shock could occur,
causing severe injury or death to per-
sonnel.
Always make sure the switch on the
power cables is in the OFF position be-
fore 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 re-
pair any power cable with a splice. The
pump motor and cable must be com-
pletely waterproof. Damage to the pump
or personal injury may result from alter-
ations.
After the pump has been installed, make
certain that the pump and all piping or
hose connections are secure before op-
eration.
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.
Obtain the services of a qualified elec-
trician to troubleshoot, test and/or ser-
vice the electrical components of this
pump.

INSTALLATION − SECTION B
Review all SAFETY information in Section A.
Do not operate this pump where explo-
sive 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 in-
stallation practices for the pump. If there are ques-
tions concerning your specific application, contact
your local distributor or the Gorman-Rupp Com-
pany.
PREINSTALLATION INSPECTION
The pump was inspected and tested before ship-
ment 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 dam-
age.
b. Check for and tighten loose attaching hard-
ware. Since gaskets tend to shrink after dry-
ing, check for loose hardware at mating sur-
faces.
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 deter-
mine 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 me-
dium being pumped. The bearings in this pump
are permanently lubricated for life. No additional lu-
brication is required.
PUMP INSTALLATION
Pump Dimensions
The pump is provided with a suction strainer to pre-
vent 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.
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.
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 fit-
ted 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-cov-
ered, 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.
The pump is provided with a suction strainer to pre-
vent large solids from clogging the impeller. Any
spherical solids which pass through the strainer
will pass through the pump.

PIPING
The pump volute is equipped with a standard
1−1/2−inch NPT tapped discharge connection.
Either hose or rigid pipe may be used for the dis-
charge connection.
For maximum pumping capacity, use non-collaps-
ible hose or rigid piping, and keep the discharge as
short and straight as possible. If rigid piping is
used, minimize the use of elbows and fittings which
increase friction losses and reduce pump perform-
ance.
A check valve or throttling valve may be installed in
the discharge line to control siphoning or back flow
when the pump is shut off.
PUMP POWER CABLE CONNECTIONS
The pump is provided with two 30-foot (3 m) power
cables. Splicing of the power cables is not recom-
mended by the Gorman-Rupp Company due to
safety and warranty considerations.
Never attempt to alter the length or re-
pair any power cable with a splice. The
pump motor and cable must be com-
pletely waterproof. Damage to the pump
or personal injury may result from alter-
ations.
When connecting the pump power cables to the
vehicle, first check the vehicle owner’s manual to
determine if the vehicle has a negative or a positive
grounding system.
Always make sure the switch on the
power cables is in the OFF position be-
fore connecting the leads to the vehicle
battery. Failure to do so could cause
arcing, resulting in explosion or fire.
Refer to Figure 3 for pump power cable connec-
tions, and proceed as follows:

OM−06490 SE SERIES
PAGE B − 4 INSTALLATION
1) Connect the red cable clamp from the pump
to the positive (+) terminal on negative
grounding systems, or to the negative (−) ter-
minal on positive grounding systems.
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
casing, electrical shock could occur,
causing severe injury or death to per-
sonnel.
2) Connect the black cable clamp from the
pump to ground, preferrably to a solid, metal-
lic, stationary point on the engine. The con-
nection should be made as far away from the
battery as possible.
