INSTALLATION
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
Use lifting equipment with a capacity of at least
3,000 pounds (1360 kg)
. This pump weighs ap-
proximately
550 pounds (249,5 kg)
, not including
the weight of accessories and base. Customer in-
stalled equipment such as suction and discharge
piping
must
be removed before attempting to lift.
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
When positioning the pump, allow a minimum
clearance of
18 inches (457 mm)
in front of the
back cover to permit removal of the cover and easy
access to the pump interior.
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
compatible with the liquid being pumped. If hose is
used in suction lines, it must be the rigid-wall, rein-
