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 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.
Only operate this pump in the direction in­
dicated by the arrow on the pump body
and on the accompanying decal. Other­
wise, the impeller could become loosened
from the shaft and seriously damage the
pump. Refer to Rotation in OPERATION,
Section C.
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 has been stored for more than 12
months, some of the components or lubri­
cants may have exceeded their maximum
shelf life. These must be inspected or re­
placed to ensure maximum pump service.
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.
POSITIONING 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.
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.
Mounting
Locate the pump in an accessible place as close as
practical to the liquid being pumped. Level mount­
ing is essential for proper operation.
The pump may have to be supported or shimmed
to provide for level operation or to eliminate vibra­
tion.
Clearance
It is recommended that 18 inches (457 mm) of
clearance be provided in front of the back cover to
permit removal of the cover and easy access to the
pump interior. A minimum clearance of 5 inches
(127,0 mm) must be maintained to permit removal
of the cover.
