INTRODUCTION
Thank You for purchasing a Gorman-Rupp pump.
Read this manual carefully to learn how to safely
install and operate your pump. Failure to do so
could result in personal injury or damage to the
pump.
The manual applies only to the submersible pump
models listed on the cover and in MAINTENANCE
AND REPAIR − SECTION E. Refer to the name-
plate on your pump to determine the specific
model, voltage, and horsepower.
The pump is driven by a waterproof electric motor.
The pump motor must be operated through an ap-
propriate control box matching the voltage and
other characteristics of the motor. The control box
must also provide for proper operation of the motor
protection devices such as the integral moisture
and thermal switches. Control boxes and other
control devices other than those integral to the
pump motor are not covered in this manual. Refer
to other literature accompanying the pump.
Pump construction is cast iron, with stainless steel
shaft and hardware. This pump is equipped with
an integral guide shoe which engages an optional
base elbow with a 3-inch discharge. The pump is
designed to handle raw, unscreened sewage and
effluents with solids up to 3.15 inches (80 mm) in

SAFETY − SECTION A
This information is specific to the Gorman-Rupp J
Series Submersible pump listed on the cover and
in MAINTENANCE AND REPAIR − SECTION E.
It applies throughout this manual to the instruc-
tions contained in the pages which follow.
In addition to this manual, see the separate litera-
ture covering the control box and other control ac-
cessories which will be used with this pump. This
literature contains essential information on install-
ing and operating the pump, and on making elec-
trical connections.
Before attempting to install, operate, or
service this pump, familiarize yourself
with this manual, and with all other liter-
ature shipped with the pump. Unfamil-
iarity with all aspects of pump operation
covered in this manual could lead to de-
struction of equipment, injury, or death.
This pump is designed to handle raw
sewage and industrial wastes at tem-
peratures of 104F (40C); do not apply
at higher temperatures. Do not attempt
to pump volatile, flammable, or corro-
sive liquids which may damage the
pump or endanger personnel as a result
of pump failure.
The electrical power used to operate
this pump is high enough to cause inju-
ry or death. Obtain the services of a qu-
alified electrician to make all electrical
connections.
Do not connect the pump motor directly
to the incoming power lines. The pump
motor is designed to operate through a
Gorman-Rupp approved control box
which provides overload protection and
power control; otherwise, the pump
warranty will be voided. Make certain
that the pump and control box are prop-
erly grounded and that the incoming
power matches the requirements of the
pump and controls. Install and operate
the control box in accordance with the
National Electric Code and all local
codes. Failure to follow the instructions
in this warning could result in injury or
death to personnel.
Do not attempt to lift this pump by the
motor power cable or the piping. Attach
proper lifting equipment to the lifting
handle, and make certain that the hook
of the lifting device is securely posi-
tioned in the apex of the handle. If
chains or cables are wrapped around
the pump to lift it, make certain that they
are positioned so as not to damage the
pump, and so that the load will be bal-
anced.
After the pump has been installed, make
certain that the pump and all piping or
hose connections are secure before op-
eration. Loose connections can result in

J SERIES OM−03690

damage to equipment and serious inju-
ry to personnel.
The following precautions should be
taken before attempting to open or ser-
vice the pump; otherwise, injury or
death could result.
1. Lock out the power to the control
panel to ensure that the pump will
remain inoperative.
2. Allow the pump to cool if over-
heated.
3. Close the discharge valve (if
used).
If this pump is used to handle sewage,
take necessary precautions during
maintenance and repair to prevent per-
sonal contamination which could result
in illness.

INSTALLATION − SECTION B
Review all SAFETY information in Section A.
This section is intended only to summarize recom-
mended installation practices for this pump. If
there are any questions concerning your specific
installation, contact your Gorman-Rupp distributor
of 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 in single pump operation, and be-
low the level of the discharge flange in du-
plex pump operation.
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. Since gaskets tend to shrink after dry-
ing, check for loose hardware at mating sur-
faces.
c. The standard pump is provided with 26 ft. (8
m.) of power cable. Inspect the cable for cuts
or damage.
d. Check that amperes, phase, voltage, and
Hertz indicated on the motor name plate
match the ratings on the control box.
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.
LUBRICATION
These pumps are equipped with a mechanical
double seal. The lower seal prevents the liquid be-
ing pumped from entering the seal housing cavity
from the pump end. The upper seal prevents oil
from escaping from the seal housing into the motor
housing, and acts as backup protection in the
event of lower seal failure.
Both ends of the shaft seal are lubricated by oil in
the seal housing (see LUBRICATION in MAINTE-
NANCE AND REPAIR − SECTION E).
The shaft bearings are permanently lubricated.
There is no other lubrication in the pump.
Pump Dimensions
See Figure B-1 for the approximate physical di-
mensions of this pump.

PUMP INSTALLATION
Lifting
Pump unit weights will vary depending on the
mounting and drive provided. Check the shipping
tag on the unit packaging for the actual weight, and
use lifting equipment with appropriate capacity.
Drain the pump and remove all customer-installed
equipment such as suction and discharge hoses
or piping before attempting to lift existing, installed
units.
Positioning the Pump
NOTE
Before installing and operating the pump, check
the direction of impeller rotation to ensure that the
pump is properly wired at the control box. See IM-
PELLER ROTATION, SECTION C.
This pump is provided with a 3-inch discharge
hose connection.
This pump is designed to be operated mounted on
guide rails and a discharge elbow/baseplate of-
fered as an option. See Figure B−1 for a typical el-
bow/baseplate installation.
The pump is equipped with a rail guide shoe which
connects to the discharge optional elbow/
baseplate. When lowered into place, the pump is
automatically and securely connected to the el-
bow/baseplate and the piping system. For infor-
mation on installing the guide rails, see the litera-
ture accompanying them.
NOTE
When engaging the guide shoe and elbow/base-
plate, make sure that the connection is not impeded
by mounting hardware, and that the guide shoe is
fully seated in the baseplate.
Engage the guide shoe at the top of the guide rails,
and lower the pump into the sump. When the
pump and guide shoe engages the discharge el-
bow/baseplate, it will form an automatic seal.
Reel in any slack control cable so that it is not
dragged into the pump suction.
Piping
NOTE
Refer to PERFORMANCE CURVES in OPERA-
TION − SECTION C when determining the most ef-
ficient piping installation.
No suction piping is required in a standard sub-
merged operation.
The optional elbow/baseplate is drilled for a
3−inch or 4−inch discharge flange connection.
Either hose or rigid pipe may be used to make dis-
charge connections. The discharge line must be
independently supported to avoid vibration and
strain on the pump. For maximum pumping capac-
