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 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 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

Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam-
age to equipment. Suction and dis-
charge hoses and piping must be re-
moved from the pump before lifting.

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.

SUCTION AND DISCHARGE PIPING

Pump performance is adversely effected by in-
creased suction lift, discharge elevation, and fric-
tion losses. See the performance curve 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
