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.
Liquid level devices are available from Gorman-
Rupp as optional equipment. For information on
installing and operating these items, refer to the lit-
erature accompanying them.
Pump Model Designation
Following is a description of the model numbering
system for S Series pumps. These submersible
pumps are available in a range of sizes. Refer to the

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 loose attaching hardware. Since
gaskets tend to shrink after drying, check for
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.
PUMP SEAL
S Series pumps utilize one of the following sealing
methods.
1. There are two shaft seals in the pump. The
lower seal prevents liquid from entering the in-
termediate cavity at the impeller end. The up-
per seal prevents oil leakage from the motor
housing cavity and acts as back-up protection
in the event of lower seal failure.
2. The pump is equipped with one double-faced
seal assembly. It is designed to prevent the
liquid being pumped from entering the inter-
mediate cavity at the impeller end, and to pre-
vent moisture from entering the motor hous-
ing cavity at the motor end.
Regardless of which sealing method is used, the
seal is lubricated by premium quality submersible
pump oil.
LUBRICATION
S series pumps are lubricated in one of the follow-
ing methods.
1. Some pumps utilize two lubrication cavities.
The motor housing cavity provides lubrication
to the motor assembly and bearings, while the
intermediate cavity provides lubrication to the
pump seal.
2. Some pumps utilize one lubrication cavity, lo-
cated just behind the seal plate. It is filled with
premium quality submersible pump oil which
lubricates the pump seal. The motor operates
in and is cooled by air, therefore it requires no
lubrication.
All S Series pumps are fully lubricated when
shipped from the factory. However, lubrication lev-
els must be checked before installing the pump
