PAGE I - 1INTRODUCTION
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.
These pumps are SE Series submersible models.
The basic material of construction is stainless
steel, with stainless steel impeller. They are de
signed to handle most non‐volatile, non‐flammable
liquids, industrial chemical and low pH resistance
materials which are mildly corrosive and abrasive
that do not contain large entrained solids. Do not
attempt to pump volatile or flammable liquids that
may damage the pump.
The pumps are powered by integral, thermally‐pro
tected electric motors which are not explosion‐
proof. The pumps may be operated fully or partially
submerged. Do not operate the pumps in hazard
ous atmospheres.
All repairs to the pump motors must be performed
by a Gorman‐Rupp authorized submersible repair
facility or the factory. Any repairs to the motor as
semblies performed by the customer or an unau
thorized 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,
please contact your Gorman‐Rupp distributor, or

The following are used to alert maintenance per
sonnel to procedures which require special atten
tion, 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 re
quired 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 possi
ble damage which could result from failure
to follow the procedure.

SAFETY ‐ SECTION A
This information applies to SE Series
submersible electric motor driven
pumps.
Because pump installations are seldom
identical, this manual cannot possibly
provide detailed instructions and pre
cautions for each specific application.
Therefore, it is the owner/installer's re
sponsibility to ensure that applications
not addressed in this manual are per
formed only after establishing that nei
ther operator safety nor pump integrity
are compromised by the installation.
Do not operate this pump where explo
sive vapors or flammable material exist.
Death or serious injury will result.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man
ual.
2. Unplug the pump power cable to
ensure that the pump will remain
inoperative.
3. Allow the pump to completely cool
if overheated.
This pump is designed to handle most
non‐volatile, non‐flammable liquids, in
dustrial chemical and low pH resistance
materials which are mildly corrosive
and abrasive and do not contain large
entrained solids. It is not designed to
pump volatile or flammable materials.
Do not attempt to pump any liquids
which may damage the pump or endan
ger personnel as a result of pump fail
ure.
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 cable, piping or the carry handle.
Attach proper lifting equipment to the
lifting handle 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.
Pumps and related equipment must be in
stalled and operated according to all na
tional, local and industry standards.

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.
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.
Pumps and related equipment must be in
stalled and operated according to all na
tional, local and industry standards.
PREINSTALLATION INSPECTION
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.
c. The pump is furnished with a 30‐foot (9 meter)
long power cable. Inspect the cable for cuts or
damage.
d. 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 and bearings in this pump are fully
lubricated from the factory. No additional lubrica
tion is required.
PUMP INSTALLATION
Pump Dimensions
The pumps are provided with suction strainers to
prevent large solids from clogging the impeller.
See Figure 1 for the approximate physical dimen
sions of the pumps.

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 on the
top of the pump. Do not lift the unit by the power
cable or the discharge piping. Customer installed
equipment such as rigid discharge piping must be
removed before attempting to lift.
Figure 2. Do Not Lift Pump by Power Cable
Do not attempt to lift the pump by the
power cable or piping. Attach proper
lifting equipment to the handle on the
pump.

PAGE B - 3INSTALLATION
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.
Never place the pump on loose or soft ground; the
pump could sink, preventing water from reaching
the impeller (see Figure 3).
Figure 3. Do Not Place Pump
on Loose Ground
Secure and support the pump by the handle on
the pump. If the bottom is heavily sludge‐covered,
rest the pump on support blocks or suspend it near
the surface of the liquid. If the application involves a
lot of debris, protect the pump from excessive wear
and clogging by suspending it in a perforated bar
rel or culvert pipe. See Figure 4 for correct 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
2-inch NPT tapped discharge connection. Either
hose or rigid pipe may be used for the discharge
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.
