SAFETY - SECTION A
This information applies to 0 Series
power take‐off pumps. Refer to the man
ual accompanying the power source be
fore 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:
1. Familiarize yourself with this man
ual.
2. Switch off the vehicle ignition and
remove the key to ensure that the
pump will remain inoperative.
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.
This pump is designed for vehicular
mounting in petroleum service. Do not
attempt to pump corrosive materials
which may damage the pump or endan
ger personnel as a result of pump fail
ure.
If this pump is used with volatile and/or
flammable liquids, be certain proper
safety practices are followed before op
erating or servicing the pump. Provide
adequate ventilation, prohibit smoking,
wear static‐resistant clothing and
shoes. Clean up all fuel spills immedi
ately after occurrence.
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.
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 operate the pump without the
shields and/or guards in place over the
rotating parts. Exposed rotating parts

TY
can catch clothing, fingers, or tools,
causing severe injury to personnel.
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.
If this pump is used with volatile and/or
flammable liquids, overheating may
produce dangerous fumes. Take pre
cautions to ensure the area surrounding
the pump is adequately ventilated. Al
low the pump to cool and use extreme
caution when venting the pump, or
when removing covers, plates, plugs, or
fitting.
Overheated pumps can cause severe
burns and injuries. If overheating of the
pump occurs:
1. Stop the pump immediately.
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.
After the vehicle is positioned for pump
maintenance, block the wheels and set
the emergency brake before attempting
to disconnect the drive shaft or remove
the pump. Be sure the pump is properly
reinstalled and secure before opera
tion.
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 completely cool before
servicing.
The gearbox provided on this pump is
designed for operation at 1000 RPM
maximum input speed. If operated at a
higher RPM, pump components may be
destroyed.
Never run this pump backwards. Be cer
tain that rotation is correct before fully
engaging the pump.
Never run the pump dry of pumping me
dium. There must be a supply of liquid to
the pump at all times to prevent destruction
of the shaft seal faces.
Pumps and related equipment must be in
stalled and operated according to all na
tional, local and industry standards.

PAGE B - 1INSTALLATION
INSTALLATION - SECTION B
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.
Do not test or operate your pump and in
tegral gearbox before reading the in
stallation and operation instructions in
this manual.
This pump is a self‐priming centrifugal model with
an integral gearbox assembly. It is designed for ve
hicular mounting in petroleum service, where the
liquid is supplied to the pump under pressure.
Since the pressure supplied to the pump is critical
to performance and safety, be sure to limit the in
coming pressure to 50% of the maximum permissi
ble operating pressure as shown on the pump per
formance curve (see Section E, Page 1).
The integral gearbox is designed to be driven
through the vehicle transfer case by a customer‐
supplied universal shaft assembly. The pump cas
ing or gearbox may be rotated in 90increments to
assist with alignment with the vehicle tank; howev
er, if the gearbox is to be rotated, some modifica
tions must be made to the gearbox to ensure ade
quate lubrication. Consult the factory for details.
For further assistance, contact your Gorman‐Rupp
distributor or the Gorman‐Rupp Company.

PAGE B - 2 INSTALLATION
PREINSTALLATION INSPECTION
The pump assembly was inspected and tested be
fore shipment from the factory. Before installation,
inspect the pump for damage which may have oc
curred during shipment. Check as follows:
a. Inspect the pump and gearbox for cracks,
dents, damaged threads, and other obvious
damage.
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. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties
indicated. Note the direction of rotation indi
cated on the pump. Check that the pump
shaft rotates in the required direction.
Only operate this pump in the direction in
dicated on the pump body and/or the ac
companying decal. Reverse rotation of the
shaft will adversely effect pump perform
ance, and the pump and/or gearbox could
be seriously damaged.
d. Check levels and lubricate as necessary. Re
fer to LUBRICATION in the MAINTENANCE
AND REPAIR section of this manual and per
form duties as instructed.
e. If the pump and gearbox have been stored for
more than 12 months, some of the compo
nents or lubricants may have exceeded their
maximum shelf life. These must be inspected
or replaced to ensure maximum pump serv
ice.
If the maximum shelf life has been exceeded, or 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.
VEHICLE REQUIREMENTS
The following instructions apply equally to new in
stallations, rebuilds or retrofits.
Tank Preparation
It is essential that any tank scale, dirt, or other for
eign material be removed from the tank and piping
prior to pump installation. Failure to do so could re
sult in clogging or damage to the pump.
Damage to the pump resulting from debris
in the suction line will not be covered by
the pump warranty.
Before connecting the suction and dis
charge piping, carefully check the storage
tank and piping for construction debris
such as nuts, bolts, wire, weld slag, and
other foreign material. Install a commer
cially available 80 mesh screen in the suc
tion line to prevent debris from entering the
pump.
POSITIONING 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.
The pump assembly can be seriously
damaged if the cables or chains used to lift
and move the unit are improperly wrapped
around the pump.
Due to the confined mounting location,
specialized equipment such as a transmis
