PUMP AND SEAL DISASSEMBLY AND
REASSEMBLY
Review all SAFETY information in Section A.
Do not attempt to service the pump as
sembly unless all power to the motor
has been shut off at the control box;
otherwise, injury or death could result.
Use a lifting device with sufficient ca
pacity. If slings or chains are used to
move the pump or components, make
sure that the load is balanced; other
wise serious personal injury or death
could result.
The maintenance and repair instructions in this
manual are keyed to the sectional views, Figures
E-1 thru E-3, and the corresponding parts lists.
Select a suitable location, preferably indoors, to
perform required maintenance. All work must be
performed by qualified personnel.
All repairs to the pump motor must be per
formed by a Gorman‐Rupp authorized
Submersible repair facility or the factory.
Any repairs to the motor assembly per
formed by the customer or an unautho
rized repair facility negates the warranty.
This section provides maintenance instructions re
quired to properly service the pump components.
Pump motor maintenance may be performed
only
by a Gorman‐Rupp authorized Submersible repair
facility, or the factory. Otherwise, the pump warran
ty will be negated, and damage to the pump, and
injury or death to personnel can result. Contact the
factory for the authorized repair facility closest to
you.
Use the hoisting bail to remove the pump from the
wet well or sump, and move it to a location where
the discharge line can be removed. It is not neces
sary to disconnect a flexible discharge hose before
removing the pump. If rigid discharge piping is
used, disconnect the piping before attempting to
move the pump.
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi
cient capacity and that they are posi
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Do not attempt to
lift this pump by the motor or control
cables, or the piping. Attach proper lift
ing equipment to the lifting bail fitted on
the pump. Lift the pump or component
only as high as necessary and keep per
sonnel away from suspended objects.
Check the chart in
TROUBLESHOOTING
, Section
D of this manual, to determine the nature of the
pump problem. If the problem is mechanical in na
ture, such as worn pump parts, seal replacement,
lubrication, etc., refer to
PUMP END DISASSEM
BLY
for instructions.
If the problem is electrical, complete disassembly
may not be required. Refer to
Electrical Testing
in
TROUBLESHOOTING
, Section D, and have a
qualified electrician check the control box, cable
and terminal housing. If the problem is determined
to be in the motor, proceed with
PUMP END DIS
ASSEMBLY,
followed by
MOTOR DISASSEMBLY
.
Otherwise, see
Terminal Housing And Power Ca
ble Disassembly
.
The electrical power used to operate
this pump is high enough to cause inju
ry or death. Make certain that the control
handle
on the control box is in the off po
sition and locked out, or that the power
supply to the control box has been
otherwise cut off and locked out, before
attempting to open or service the pump
