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-
