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.

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 Gorman‐Rupp Company:

SAFETY - SECTION A

This information applies to 0 Series
electric motor driven pumps. Refer to
the manual accompanying the motor
before attempting to begin operation.

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.

Before attempting to open or service the
pump:

corrosive, or flammable materials which
may damage the pump or endanger per
sonnel as a result of pump failure.

This pump is designed to handle petro
leum products or other industrial liq
uids that do not contain large entrained
solids. All controls must meet industry
standards and codes for use in an ex
plosive atmosphere. Do not attempt to
pump liquids for which the pump and/or
controls have not been approved, or
which may damage the pump or endan
ger personnel as a result of pump fail
ure.

1. Familiarize yourself with this man
ual.

2. Disconnect the incoming power to
the motor and lock it out to ensure
that the pump will remain inopera
tive.

3. Allow the pump to completely cool
if overheated.

4. Check the temperature before
opening any covers, plates, or
plugs.

5. Close the suction and discharge
valves.

6. Vent the pump slowly and cau
tiously.

7. Drain the pump.

Be certain proper safety practices are
followed before operating or servicing
the pump. Provide adequate ventilation,
prohibit smoking, wear static‐resistant
clothing and shoes. Clean up all fuel
spills immediately after occurrence.

Do not install and operate a non‐explo
sion proof motor in an explosive atmo
sphere. Install, connect, and operate
the motor in accordance with the Na
tional Electric Code and all local codes.
If there is a conflict between the instruc
tions in the manual accompanying the
unit and the National Electric Code or
the applicable local code, the National
or local code shall take precedence.

This pump is designed to handle petro
leum products or other industrial liq
uids that do not contain large entrained
solids. Do not attempt to pump volatile,

Because this pump is designed to han
dle volatile and/or flammable liquids,

overheating may produce dangerous
fumes. Take precautions to ensure the
area surrounding the pump is ade
quately ventilated. Allow the pump to
cool and use extreme caution when
venting the pump, or when removing
covers, plates, plugs, or fittings.

After the pump has been positioned,
make certain that the pump and all pip
ing connections are tight, properly sup
ported and secure before operation.

Do not remove plates, covers, gauges,
pipe plugs, or fittings from an over
heated pump. Vapor pressure within the
pump can cause parts being disen
gaged to be ejected with great force. Al
low the pump to cool before servicing.

Do not operate the pump against a
closed discharge valve for long periods
of time. If operated against a closed dis
charge valve, pump components will
deteriorate, and the liquid could come
to a boil, build pressure, and cause the
pump casing to rupture or explode.

2. Ventilate the area.

3. Allow the pump to completely cool.

4. Check the temperature before
opening any covers, plates,
gauges, or plugs.

5. Vent the pump slowly and cau
tiously.

6. Refer to instructions in this manual
before restarting the pump.

The electrical power used to operate
this pump is high enough to cause inju
ry or death. Obtain the services of a qu
alified electrician to troubleshoot, test
and/or service the electrical compo
nents of this pump.

Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi
cient capacity and that they are posi
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Suction and dis
charge hoses and piping must be re
moved from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away
from suspended objects.

Overheated pumps can cause severe
burns and injuries. If overheating of the
pump occurs:

1. Stop the pump immediately.

PAGE A - 2 SAFETY

Pumps and related equipment must be in
stalled and operated according to all na
tional, local and industry standards.

INSTALLATION - SECTION B

OM-010970 SERIES

Review all SAFETY information in Section A.

Since pump installations are seldom identical, this
section offers only general recommendations and
practices required to inspect, position, and ar
range the pump and piping.

Most of the information pertains to a standard
static lift application where the pump is posi
tioned above the free level of liquid to be pumped.

If installed in a flooded suction application where
the liquid is supplied to the pump under pressure,
some of the information such as mounting, line
configuration, and priming must be tailored to the

OUTLINE DRAWING

specific application. Since the pressure supplied
to the pump is critical to performance and safety,
be sure to limit the incoming pressure to 50% of
the maximum permissible operating pressure as
shown on the pump performance curve.

For further assistance, contact your Gorman‐Rupp
distributor or the Gorman‐Rupp Company.

sions of this pump.
