INSTALLATION

INSTALLATION − SECTION B

Review all SAFETY information in Section A.

Since pump installations are seldom identical, this
section offers only general recommendations and
practices required to inspect, position, and ar-
range the pump and piping.

Most of the information pertains to a standard
static lift application where the pump is positioned
above the free level of liquid to be pumped.

If installed in a flooded suction application where
the liquid is supplied to the pump under pressure,
some of the information such as mounting, line
configuration, and priming must be tailored to the
specific application. Since the pressure supplied
to the pump is critical to performance and safety,
be sure to limit the incoming pressure to 50% of the
maximum permissible operating pressure as
shown on the pump performance curve (see Sec-
tion E, Page 1).

For further assistance, contact your Gorman-Rupp
distributor or the Gorman-Rupp Company.

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 and engine 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.

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.
