PUMP AND SEAL DISASSEMBLY
AND REASSEMBLY
Review all SAFETY information in Section A.
Follow the instructions on all tags, label and decals
attached to the pump.
This pump requires little service due to its rugged,
minimum‐maintenance design. However, if it be­
comes necessary to inspect or replace the wearing
parts, follow these instructions which are keyed to
the sectional view (see Figure E‐1) and the accom­
panying parts list.
This manual will alert personnel to known proce­
dures which require special attention, to those
which could damage equipment, and to those
which could be dangerous to personnel. However,
this manual cannot possibly anticipate and provide
detailed precautions for every situation that might
occur during maintenance of the unit. Therefore, it
is the responsibility of the owner/maintenance per­
sonnel to ensure that only safe, established main­
tenance procedures are used, and that any proce­
dures not addressed in this manual are performed
only after establishing that neither personal safety
nor pump integrity are compromised by such prac­
tices.
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.
Before attempting to service the pump, disconnect
or lock out incoming power and take precautions
to ensure that it will remain inoperative. Close any
valves in the discharge line.
PUMP END DISASSEMBLY
Follow the instructions on all tags, label and decals
attached to the pump.
The electrical power used to operate
this pump is high enough to cause inju­
ry or death. Make certain that the plug
on the pump power cable is discon­
nected from its receptacle before ser­
vicing.
Nuts, bolts, and screws used on this pump
are metric and do not match standard En­
glish‐measurement threads. If any
threaded hardware is replaced, it must be
replaced with metric type. Attempting to
force in a fastener with English threads will
damage the mating threads. An optional
discharge adaptor is available to convert
the metric pipe threads in the discharge
flange to American pipe threads.
Use the lifting rope (56) 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
necessary to disconnect the discharge hose be­
fore removing the pump.
Do not attempt to lift the pump by the
motor power cable or the piping. Use
the lifting rope fitted to the pump. If
chains or cable 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.
Select a suitable location, preferably indoors, to
perform the degree of maintenance required. If the
motor housing is to be opened, the work must be
done in a clean, well‐equipped shop. All mainte­
nance functions must be done by qualified person­
nel.
Check the chart in TROUBLESHOOTING, Section
D, to determine the nature of the pump problem. If
