any liquids which may damage the
pump or endanger personnel as a result
of pump failure.
If this pump is used with volatile and/or
flammable liquids, be certain proper
safety practices are followed before op-
Do not operate the pump against a
closed discharge valve for long periods
of time. If operated against a closed discharge 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-

OM−01247
cautions to ensure the area surrounding
the pump is adequately ventilated. Allow the pump to cool and use extreme
caution when venting the pump, or
when removing covers, plates, plugs, or
fitting.
Do not remove plates, covers, gauges,
pipe plugs, or fittings from an overheated pump. Vapor pressure within the
pump can cause parts being disengaged to be ejected with great force. Allow the pump to cool before servicing.
0 SERIES
Never tamper with the governor to gain
more power. The governor establishes
safe operating limits that should not be
exceeded. Limit the maximum input
speed and operation range as indicated
on the performance curve on Page E-1.
The gearbox provided on this pump is
designed for operation at 1900 RPM
maximum input speed. If operated at a
higher RPM, pump components may be
destroyed.
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 operation.
Never run the pump dry of pumping medium. There must be a supply of liquid to
the pump at all times to prevent destruction
of the shaft seal faces.
PAGE A − 2 SAFETY
INSTALLATION − SECTION B
OM−012470 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 arrange the pump and piping.
Do not test or operate your pump and integral
gearbox before reading the installation and operation instructions in this manual.
These pumps are self-priming centrifugal models
with an integral gearbox assembly. Each of the
pumps covered by this manual is designed for vehicular 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 permissible operating pressure as shown on the pump performance curve (see Section E, Page 1).
The integral gearbox is designed to be driven
through the vehicle transfer case by a customersupplied universal shaft assembly. The pump casing or gearbox may be rotated in 45_ increments to
assist with alignment with the vehicle tank; however, if the gearbox is to be rotated, some modifications must be made to the gearbox to ensure adequate lubrication. Consult the factory for details.
For further assistance, contact your Gorman-Rupp
distributor or the Gorman-Rupp Company.

PREINSTALLATION INSPECTION
The pump assembly was inspected and tested before shipment from the factory. Before installation,
inspect the pump for damage which may have occurred 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 drying, check for loose hardware at mating surfaces.
c. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties
indicated.Note the direction of rotation indicated on the pump. Check that the pump
shaft rotates in the required direction.
Only operate this pump in the direction indicated on the pump body and/or the accompanying decal. Reverse rotation of the
shaft will adversely effect pump performance, 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 perform duties as instructed.
e. If the pump and gearbox have been stored for
more than 12 months, some of the components or lubricants may have exceeded their
maximum shelf life. These must be inspected
or replaced to ensure maximum pump service.
VEHICLE REQUIREMENTS
The following instructions apply equally to new installations, rebuilds or retrofits.
Tank Preparation
It is essential that any tank scale, dirt, or other foreign material be removed from the tank and piping
prior to pump installation. Failure to do so could result 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 discharge piping, carefully check the storage
tank and piping for construction debris
such as nuts, bolts, wire, weld slag, and
other foreign material. Install a commercially available 80 mesh screen in the suction 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
If the maximum shelf life has been exceeded, 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 appropriate action has
been taken.
PAGE B − 2 INSTALLATION
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-
OM−012470 SERIES
sion jack with custom brackets should be
used to lift and position the pump and
gearbox.
NOTE
If the gearbox is rotated out of the standard position
shown in Figure 1, the oil fill and drain plugs must
be relocated. The magnetic drain plug must be relocated to the lowest port, and the oil vent and elbow must be relocated to the highest port. Consult
the factory for correct positioning of the fill plug to
provide for proper lubrication of the gearbox.
ALIGNMENT
When installing and/or aligning universal shaft
assemblies, switch off the vehicle ignition and
remove the key to ensure that the pump will remain inoperative.
The alignment of the pump and its power source is
critical for trouble-free mechanical operation. Before checking alignment, make sure that the gearbox mounting bolts are tight.
When connecting the universal joint drive shaft assembly to a PTO unit, install, support, and align the
drive shaft in accordance with the manufacturer’s
instructions. The pump and the drive power source
are generally positioned so that shaft centerlines
are parallel and horizontal. The maximum operating angle should not exceed 15 degrees (see Figure 2).
Check the direction of rotation of the PTO unit before starting the pump. The drive shaft must rotate
in the direction shown on the body of the pump,
gearbox, and/or decals, tags, and labels.
Do not operate the pump without the guard in
place over the rotating parts. Exposed rotating
parts can catch clothing, fingers, or tools, causing severe injury to personnel.
After the power take-off has been aligned, block
the wheels of the external power source, engage
the braking system, or take other precautions to
ensure that the power source will remain stationary. Block the wheels on the unit to prevent creeping.
