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 impeller.
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 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 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
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.
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 10 inches
(254 mm) must be maintained to permit removal of
the cover.
SUCTION AND DISCHARGE PIPING
Pump performance is adversely effected by in­
creased suction lift, discharge elevation, and fric­
tion losses. See the performance curve and oper­
ating range shown on Page E‐1 to be sure your
overall application allows pump to operate within
the safe operation range.
Materials
Either pipe or hose maybe used for suction and
discharge lines; however, the materials must be
