INSTALLATION - SECTION B
Review all SAFETY information in Section A.
Since pump installations are seldom identical, this
section is intended only to summarize general rec­
ommendations and practices required to inspect,
position, and arrange the pump and piping. If there
are any questions concerning your specific instal­
lation, contact your Gorman‐Rupp distributor or
the Gorman‐Rupp Company.
The motor in these pumps is not designed
to be operated in air for more than 10 min­
utes without overheating. The pumps must
be operated through liquid level controls to
maintain the level of liquid in the wet well so
that power to the motor is cut off when liq­
uid falls below the midpoint of the motor
housing.
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.
c. Inspect the power cable for cuts or any other
obvious damage.
d. Check that amperes, phase, voltage, and
hertz indicated on the motor name plate
match the ratings on the control box and in­
coming power.
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 LUBRICATION in
MAINTENANCE AND REPAIR - SECTION
E.
PUMP SEALS
This pump is equipped with two mechanical seals.
The lower seal is lubricated by the liquid being
pumped and prevents the liquid from entering the
seal housing cavity from the pump end. The upper
seal prevents oil from escaping from the seal hous­
ing into the motor housing and acts as backup pro­
tection in the event of lower seal failure.
LUBRICATION
The seal cavity is fully lubricated when shipped
from the factory. However, the lubrication level
must be checked before installing the pump (see
LUBRICATION in MAINTENANCE AND REPAIR
- SECTION E). If the oil level is abnormally low, de­
termine the cause before putting the pump into
service.
The shaft bearings are permanently lubricated.
There is no other lubrication in the pump.
