ing, check for and tighten loose hardware at
the mating surfaces.
c. Inspect the power cable for cuts or any other
obvious damage.
d. Check that amperes, phase, voltage and
hertz indicated on the name plate match the
ratings on the control box and incoming pow-
er.
e. Carefully read all tags, decals, and markings
on the pump, and perform all duties indicated.
f. Check for oil leaks. If there is any indication of
an oil leak, see LUBRICATION at the end of
this manual.
g. 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 exceed, or if
anything appears to be abnormal, contact
your Gorman-Rupp distributor or the factory
to determine the repair or updating policy. Do
not put the pump into service until appropri-
ate action has been taken.
PUMP SEAL
The pump is equipped with one double-faced seal
assembly. It is designed to prevent the liquid being
pumped from entering the lubrication cavity at the
impeller end, and to prevent moisture or lubrication
oil from entering the motor housing cavity at the
motor end.
The seal is lubricated by premium quality submers-
ible pump oil.
LUBRICATION
The pump utilizes one lubrication cavity, located
between the pump casing and the motor housing.
It is filled with premium quality submersible pump
oil which lubricates the pump seal. The motor oper-
ates in and is cooled by air, therefore it requires no
lubrication.
The pump was fully lubricated when shipped from
the factory. However, lubrication levels must be
checked before installing the pump (see LU-
BRICATION in Section E, MAINTENANCE AND
REPAIR). If the oil level is abnormally low, deter-
mine the cause before putting the pump into ser-
vice.
Refer to Table B-2 for oil capacity and position for
filling the seal cavity in each pump. Refer to LU-
BRICATION, Section E for lubrication specifica-
tions and intervals.
