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 cast iron. They
are designed to handle most non‐volatile, non‐
flammable liquids that do not contain large en
trained 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. Do not operate the pumps in hazardous at
mospheres.

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.

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

SAFETY

Because pump installations are seldom
identical, this manual cannot possibly pro
vide detailed instructions and precautions
for each specific application. Therefore, it
is the owner/installer's responsibility to en
sure that applications not addressed in this
manual are performed only
ing that neither operator safety nor pump
integrity are compromised by the installa
tion.

Before attempting to open or service the
pump:

after establish

1. Familiarize yourself with this man
ual.

2. Unplug the power cable from its re
ceptacle to ensure that the pump
will remain inoperative.

3. Allow the pump to completely cool
if overheated.

5. Close the discharge valve (if
used).

Never attempt to alter the length or repair
any power cable with a splice. The pump
motor and cable must be completely water
proof. Injury or death may result from alter
ations.

All electrical connections must be in accor
dance with The National Electric Code and
all local codes. If there is a conflict between
the instructions provided and N.E.C. Speci
fications, N.E.C. Specifications shall take
precedence. All electrical equipment sup
plied with this pump was in conformance
with N.E.C. requirements in effect on the
date of manufacture. Failure to follow appli
cable specifications, or substitution of elec
trical parts not supplied or approved by the
manufacturer, can result in severe injury or
death and void warranty.

This pump is designed to handle dirty water
that does not contain large entrained sol
ids. This pump is not
atile, explosive, or flammable materials. Do
not attempt to pump any liquids for which
you pump is not approved, or which may
damage the pump or endanger personnel
as a result of pump failure.

The electrical power used to operate this
pump is high enough to cause injury or
death. Make certain that the power cable re
ceptacle is properly grounded before
installation. Make certain that the plug on
the pump power cable is disconnected from
its receptacle before servicing.
