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.
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. Suction and dis
charge hoses and piping must be re
moved from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away
from suspended objects.
The maintenance and repair instructions in this
manual are keyed to the sectional views, Figures
E-1 and E-2, 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.
Use
Only Genuine Gorman-Rupp
re
placement parts. Failure to do so may cre
ate a hazard and damage the pump or di
minish optimal pump performance. Any
such hazard, damage or diminished per
formance is not covered by the warranty.
NOTE
When appropriate recycling facilities are available,
the user should recycle components and fluids
when doing any routine maintenance / repairs and
also at the end of the pump’s useful life. All other
components and fluids shall be disposed of ac
cording to all applicable codes and regulations.
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.
Do not attempt to lift the pump by the
motor power cable or the piping. Attach
proper lifting equipment to the lifting
device fitted to the pump. If chains or
cable are wrapped around the pump to
lift it, make certain that they are posi
tioned so as not to damage the pump,
and so that the load will be balanced.
