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 warnings and cautions con­
tained in this manual or affixed to the pump,
and perform all duties indicated. Note the di­
rection of rotation indicated on the pump.
Check that the pump shaft rotates counter­
clockwise when facing the pump suction.
Only operate this pump in the direction in­
dicated by the arrow on the pump body
and on the accompanying decal. Refer to
ROTATION in OPERATION, Section C.
d. Check all lubricant levels and lubricate as
necessary. Refer to LUBRICATION in the
MAINTENANCE AND REPAIR section of this
manual and perform duties as instructed.
e. If the pump and power source have been
stored for more than 12 months, some of the
components or lubricants may have ex­
ceeded their maximum shelf life. These must
be inspected or replaced to ensure maxi­
mum 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
Lifting
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.
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.
SUCTION AND DISCHARGE PIPING
The size of the system piping is not always deter­
mined by the nominal suction and discharge port
diameter. Factors such as suction lift, discharge
elevation, and friction losses for the complete sys­
tem must be considered to be sure your applica­
tion allows the pump to operate within the safe op­
erating range shown on page E‐1. In any case, the
