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 is an SE Series submersible pump. The basic
material of construction is cast iron, with stainless
steel hardware and fittings. The pump is light
weight and portable, making it ideally suited to
many domestic and industrial applications where
low capacity dewatering or irrigation is required.
The pump is powered by an integral, thermally-
protected electric motor which is not explosion-
proof. The pump may be operated fully or partially
submerged. Do not operate the pump in a hazard-
ous atmosphere.
All repairs to the pump motor must be performed
by a Gorman-Rupp authorized submersible repair
facility or the factory. Any repairs to the motor as-
sembly performed by the customer or an unautho-
rized repair facility negates the warranty.
Because pump installations are seldom identical,
this manual cannot possibly provide detailed in-
structions and precautions for every aspect of
each specific application. Therefore, it is the re-
sponsibility of the owner/installer of the pump to
ensure that applications not addressed in this
manual are performed only after establishing that
neither operator safety nor pump integrity are com-
promised by the installation. Pumps and related
equipment must be installed and operated ac-
cording to all national, local and industry stan-
dards.
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,

INSTALLATION − SECTION B
GENERAL INFORMATION
Review all SAFETY information in Section A.
Since pump installations are seldom identical, this
section is intended only to summarize general rec-
ommendations and practices required to inspect,
position, and arrange the pump and piping. If there
are any questions concerning your specific instal-
lation, contact your Gorman-Rupp distributor or
the Gorman-Rupp Company.
Nuts, bolts and screws used on this pump
are metric and do not match standard SAE
measurement threads. If any threaded
hardware is replaced, it must be replaced
with metric type. Attempting to force in a
fastener with SAE threads will damage the
mating threads. An optional discharge
adaptor is available to convert the metric
pipe threads in the discharge flange to the
SAE threads.
PREINSTALLATION INSPECTION
The pump assembly was inspected and tested be-
fore shipment from the factory. Before installation,
check for damage which may have occurred dur-
ing 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 and tighten loose hardware at
the mating surfaces.
c. Inspect the power cable for cuts or any other
obvious damage.
d. Check that amperes, phase, voltage and
hertz indicated on the name plate match the
ratings on the control box and incoming pow-
er.
e. Carefully read all tags, decals, and markings
on the pump, and perform all duties indicated.
f. Check for oil leaks. If there is any indication of
an oil leak, see LUBRICATION at the end of
this manual.
g. If the pump has been stored for more than 12
months, some of the components or lubri-
cants may have exceeded their maximum
shelf life. These must be inspected or re-
placed to ensure maximum pump service.
If the maximum shelf life has been exceed, or 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 appropri-
ate action has been taken.
PUMP SEAL
The pump is equipped with a single faced seal as-
sembly. It is designed to prevent the liquid being
pumped from entering the lubrication cavity at the
impeller end. A lip seal is used to prevent moisture
or lubrication oil from entering the motor housing
cavity at the motor end.
The seal is lubricated by premium quality submers-
ible pump oil.
LUBRICATION
The pump is equipped with one double-faced seal
assembly. It is designed to prevent the liquid being
pumped from entering the lubrication cavity at the
impeller end, and to prevent moisture or lubrication
oil from entering the motor housing cavity at the
motor end.
This pump was fully lubricated when shipped from
the factory. However, lubrication levels must be
checked before installing the pump (see LU-
BRICATION in the MAINTENANCE AND REPAIR
MANUAL). If the oil level is abnormally low, deter-
mine the cause before putting the pump into ser-
vice.
Refer to Table B-2 for the oil capacity and position
for filling the seal cavity in the pump. Refer to LU-
BRICATION, Section C for lubrication specifica-
tions and intervals.

When installing or servicing the pump
or controls, follow all requirements for
the installation of wiring or electrical
equipment as outlined in the National
Electric Code. Follow all safety require-
ments. Failure to observe these require-
ments could result in injury or death to
personnel.
NOTE
Refer to the performance curve in Section E, Main-
tenance and Repair when determining the most
efficient piping installation. The recommended
maximum submergence depth is 23 feet. Great-
er depths could result in damage to the pump
Pump Dimensions
For the approximate physical dimensions of your
pump, refer to the pump specification data sheet
or contact your Gorman-Rupp distributor or the
Gorman-Rupp Company.
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.
Do not attempt to lift the pump by the
motor power cable or the piping. Attach
proper lifting equipment or a rope to the
lifting device fitted to the pump.
Positioning the Pump
The pump is designed to operate fully or partially
submerged. The rotating parts are oil lubricated,
and the motor is cooled by a constant flow of liquid
or air discharged through internal passages.
The pump will operate if positioned on its side, but
this is not recommended because the motor

OM−06493 SE SERIES
PAGE B − 3INSTALLATION
torque could cause the pump to roll during opera-
tion.
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 sus-
pending 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 B-1 for typical pump installations.
All liquid entering the pump must pass through a
strainer screen. Any spherical solids which pass
through the screen will pass through the pump.
BY BAIL IN PERFORATED CULVERT PIPE ON SUPPORTS
Figure B-1. Typical Pump Installations
Piping
No suction piping is required in a standard installa-
tion. This pump is provided with a suction strainer
to prevent large solids from clogging the impeller.
To determine the size of the discharge connection,
see Table B-1. Either hose or rigid pipe may be
used. To facilitate mobility and maintenance, it is
recommended that the discharge line be fitted with
a quick disconnect fitting near the pump. The dis-
charge line must be independently supported to
avoid strain and vibration on the pump.
Either hose or rigid pipe may be used to make dis-
charge connections. For maximum pumping ca-
pacity, keep the line as short and straight as pos-
sible. Elbows and fittings used in discharge lines
increase friction loss, minimize their use.
It is recommended that a check valve or throttling
valve be installed in the discharge line to control si-
phoning or back flow when the pump is shut off.
ELECTRICAL CONNECTIONS
Install and operate this pump in accor-
dance with the National Electrical Code
and all local codes. Have a qualified
electrician perform all checks and con-
nections in this section.
Never attempt to alter the length of the
pump motor cable or to repair it with a
splice. The power cable and pump mo-
tor must be kept completely waterproof.
