INSTALLATION − SECTION B
Review all SAFETY information in Section A.
This section is intended only to summarize recom-
mended installation practices for this pump. If
there are any questions concerning your specific
installation, contact your Gorman-Rupp distributor
of the Gorman-Rupp Company.
Automatic liquid level controls are available from
Gorman-Rupp as options. For information on in-
stalling and operating these controls, see the tech-
nical data accompanying them.
PREINSTALLATION INSPECTION
The pump assembly was inspected and tested be-
fore shipment from the factory. Before installation,
check for damage which may have occurred dur-
ing shipment. Check as follows:
a. Inspect the pump assembly for cracks, dents,
damaged threads, and other obvious dam-
age.
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. The standard pump is provided with 26 ft. (8
m.) of power cable. Inspect the cable for cuts
or damage.
d. Check that amperes, phase, voltage, and
Hertz indicated on the motor name plate
match the ratings on the control box.
e. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties
indicated.
f. Check for any oil leaks. If there is any indica-
tion of an oil leak, see

in

.
LUBRICATION
These pumps are equipped with a mechanical
double seal. The lower seal prevents the liquid be-
ing pumped from entering the seal housing cavity
from the pump end. The upper seal prevents oil
from escaping from the seal housing into the motor
housing, and acts as backup protection in the
event of lower seal failure.
Both ends of the shaft seal are lubricated by oil in
the seal housing (see
LUBRICATION
in
MAINTE-
NANCE AND REPAIR − SECTION E
).
The shaft bearings are grease lubricated.
There is no other lubrication in the pump.
