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 posi­
tioned 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.
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 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.
