These J Series pumps are driven by a waterproof
submersible electric motor. The motor is dual volt-
age, but is shipped from the factory wired only for
the voltage shown on the nameplate. Contact the
factory before attempting to change to the alter-
native voltage.
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. These J Series pumps are
equipped with an integral guide shoe which en-
gages an optional base elbow with a 4−inch dis-
charge; they will handle solids up to 3−inches in
diameter. The pumps are designed to operate fully
or partially submerged mounted on guide rails in-
stalled in a wet well, and to handle raw, unscreened
sewage and effluents. Installation of the guide rail
system and other wet well hardware is not covered
in this manual. Refer to other literature accompa-
nying the pump.

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. Check the pump assembly for cracks,
dents, damaged threads, and other obvi−
ous damage.
b. Check for loose attaching hardware. Since
gaskets tend to shrink after drying, check
for loose hardware at mating surfaces.
c. The standard pump is provided with 26 ft.
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 mark−
ings on the pump assembly, and perform all
duties indicated.
f. Check for any oil leaks. If there is any indi−
cation of an oil leak, see LUBRICATION in
MAINTENANCE AND REPAIR − SECTION
E.
LUBRICATION
The shaft seal I is lubricated by oil in the seal hous-
ing (see LUBRICATION in MAINTENANCE AND
REPAIR − SECTION E).
The shaft bearings are grease lubricated.
There is no other lubrication in the pump.

PUMP INSTALLATION
Lifting
Use lifting equipment with a capacity of at least
1,850 lbs. Each version of these pumps weighs
approximately 369 lbs., not including the weight of
customer−installed accessories such as the el-
bow/baseplate and piping. Discharge hose or pip-
ing must be removed before attempting to lift the
pump.
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 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 optional discharge elbow/base−
plate. When lowered into place, the pump is auto-
matically and securely connected to the elbow/
baseplate and the piping system; the pump can be
removed or installed without personnel entering
the wet well.
For information on installing the guide rails, see the
literature accompanying them.
NOTE
When engaging the guide shoe and elbow/base-
plate, make sure that the connection is not imped-
ed 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 guide shoe engages the discharge elbow/
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 OPERATION
− SECTION C when determining the most efficient
piping installation. The recommended maximum
submergence depth is 65 feet.
No suction piping is required in a standard sub-
merged operation.

OM−03592−OM01JSV4F−G60 DV
PAGE B−4 INSTALLATION
The optional discharge elbow/baseplate is drilled
for a 3−inch or 4−inch discharge flange connec-
tion. Either hose or rigid pipe may be used to make
discharge connections.
The discharge line must be independently sup-
ported to avoid vibration and strain on the pump.
For maximum pumping capacity, keep the line as
short and straight as possible. Elbows and fittings
used in a discharge line increase friction losses;
minimize their use.
It is recommended that a check valve or throttling
valve be installed in the discharge line to control si-
phoning or back flow when the pump is shut off.

OPERATION − SECTION C
PERFORMANCE CURVES
In the performance curves which follow, perform-
ance is based on 70_F clear water at sea level. The
performance of your pump may be different due to
such factors as viscosity, specific gravity, elevation,
temperature, and impeller trim.
NOTE
These curves appy to standard production models.
If your pump serial number is followed by an "N",
your pump is not a standard production model.
Contact the Gorman−Rupp Company to verify per-
formance.
PERFORMANCE CURVE − JSV4F60−E8.7
NOTE
The curve shows 460 volt performance only. For 230 volt performance, multiply amperage shown by 2.

WARNING
OVERHEATED PUMPS CAN CAUSE SEVERE
BURNS AND INJURY. IF THE PUMP BECOMES
OVERHEATED:
1. STOP THE PUMP IMMEDIATELY.
2. ALLOW THE PUMP TO COOL.
3. REFER TO INSTRUCTIONS IN THIS
MANUAL BEFORE RESTARTING THE
PUMP.
Overheating can occur if the pump is misapplied; if
it is started more than 20 times within one hour; if
the control box fails to provide overload or thermal
protection, or if the pump is operated against a
closed discharge valve for an extended period of
time.
Impeller Rotation
FIGURE C−1. PUMP ROTATION
Refer to Figure C−1, and check impeller rotation
as follows before installing the pump on rails or in a
wet well.

ÉÉÉÉÉÉ
CAUTION
WHILE CHECKING IMPELLER ROTATION, SE-
CURE THE PUMP TO PREVENT THE MOTOR
POWER CABLE FROM COILING.
Suspend the pump by the lifting handle. Apply
power briefly and note the direction of pump twist.
As viewed from the top, the pump should twist in a
counterclockwise direction; this will indicate that
impeller rotation is correct.
If the pump twists in a clockwise direction, impeller
rotation is incorrect. Have qualified personnel inter-
change the control box connections of any two
pump motor power leads. Recheck pump twist; it
should now be in a counterclockwise direction.

CAUTION
DO NOT ATTEMPT TO OPERATE THE PUMP UN-
TIL IMPELLER ROTATION HAS BEEN CHECKED;
OTHERWISE, THE PUMP WILL BE DAMAGED.
NEVER START THE PUMP MORE THAN 20 TIMES
WITHIN ONE HOUR. THE MOTOR MUST COOL
BETWEEN STARTS; OTHERWISE, IT WILL OVER-
HEAT AND DAMAGE MOTOR WINDINGS AND/OR
CONTROL BOX COMPONENTS.
Follow the control box manufacturer’s instructions,
start the pump, and run any recommended
checks.

WARNING
THE INTEGRAL THERMAL OVERLOAD DEVICE
WILL SHUT OFF THE MOTOR IF THE TEMPERA-
TURE RISES ABOVE DESIGN LIMITS. WHEN
THE PUMP COOLS AND THE TEMPERATURE
FALLS BELOW THESE LIMITS, THE MOTOR
WILL RESTART AUTOMATICALLY. TO AVOID
THE HAZARDS OF AN UNEXPECTED MOTOR
START−UP, DO NOT ATTEMPT TO HANDLE OR
SERVICE THE PUMP UNLESS ALL POWER TO
THE MOTOR HAS BEEN SHUT OFF AT THE
CONTROL BOX; OTHERWISE, SERIOUS PER-
SONAL INJURY COULD RESULT.
DURING MOTOR SHUTOFF BY THE THERMAL
OVERLOAD DEVICE, CONTROL BOX CIRCUITS
REMAIN LIVE. DO NOT ATTEMPT TO SERVICE
ANY CONTROL BOX COMPONENTS UNLESS
INCOMING POWER HAS BEEN SHUT OFF.
After stopping the pump, be sure to perform all re-
quired maintenance and preservation procedures.
Cold Weather Preservation
The pump will not freeze as long as the casing is
submerged in liquid. If the casing is not sub-
merged, or if the liquid begins to freeze, remove the
pump from the wet well and dry it thoroughly. Run
the pump for two or three minutes to dry the inner
walls.
If the pump does freeze while it is out of the liquid,
submerge it until thawed; if the liquid is near freez-
ing, the pump must be submerged for an extended
period of time. Check thawing by starting the pump
and checking that the shaft rotates freely. If the
pump remains frozen allow additional thawing time
before attempting to restart.
If submerging does not thaw the pump, move it
into a warm area until completely thawed.

WARNING
DO NOT ATTEMPT TO THAW THE PUMP BY US-
ING A TORCH OR OTHER SOURCE OF FLAME.
THIS COULD DAMAGE O−RINGS OR HEAT
THE OIL IN THE SEAL HOUSING ABOVE CRITI-
CAL TEMPERATURES, CAUSING THE PUMP
TO RUPTURE OR EXPLODE.
Operations Checks
To detect minor problems, check the pump for
proper operation when it is first started and at peri-
odic intervals.
