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
There are two shaft seals in the pump. The lower
seal prevents liquid from entering the intermediate
cavity at the impeller end. The upper seal prevents
oil leakage from the motor housing cavity and acts
as back‐up protection in the event of lower seal fail­
ure.
LUBRICATION
These pumps utilize two lubrication cavities. The
motor housing cavity provides lubrication to the
motor assembly and bearings, while the intermedi­
ate cavity provides lubrication to the pump seal.
The pumps are fully lubricated when shipped from
the factory. However, lubrication levels must be
checked before installing the pump (see LU­
BRICATION in MAINTENANCE AND REPAIR -
SECTION E). An additional quart (0,9 liter) of oil is
provided to “top off” the oil level in the pump motor
cavity. If the oil level is abnormally low, determine
the cause before putting the pump into service.
Due to differences in pump design, the quantity of
oil and manner in which oil is to be added to the
seal cavity varies between pump models. Refer to
Table B‐2 for oil capacities and positions for filling
the seal cavity in each pump. Motor cavities requir­
ing lubrication should always be positioned verti­
cally for filling. Refer to LUBRICATION, Section C
for lubrication specifications and intervals.
PUMP INSTALLATION
When installing or servicing the pump
or controls, follow all requirements for
the installation of wiring or electrical
