INSTALLATION - SECTION B
GENERAL INFORMATION
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.
Nuts, bolts and screws used on this pump
are metric and do not match standard SAE
measurement threads. If any threaded
hardware is replaced, it must be replaced
with metric type. Attempting to force in a
fastener with SAE threads will damage the
mating threads. An optional discharge
adaptor is available to convert the metric
pipe threads in the discharge flange to the
SAE threads.
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 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 a single faced seal as­
sembly. It is designed to prevent the liquid being
pumped from entering the lubrication cavity at the
impeller end. A lip seal is used 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.
This pump was fully lubricated when shipped from
the factory. However, lubrication levels must be
checked before installing the pump (see LU­
BRICATION in the MAINTENANCE AND REPAIR
MANUAL). If the oil level is abnormally low, deter­
mine the cause before putting the pump into ser­
vice.
Refer to Table B‐2 for the oil capacity and position
for filling the seal cavity in the pump. Refer to LU­
BRICATION, Section C for lubrication specifica­
tions and intervals.
