PUMP AND SEAL DISASSEMBLY AND
REASSEMBLY
Review all SAFETY information in Section A.
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 illustrations (see Figures E-1 and E-2) and
the corresponding parts lists.
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.
Do not attempt to service the pump as
sembly unless all power to the motor
has been shut off at the control box; oth
erwise, 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. 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.
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.
Select a suitable location, preferably indoors, to
perform required maintenance. All work must be
performed by qualified personnel.
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 DISAS
SEMBLY
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 cable(s) or terminal housing, see
MO
TOR DISASSEMBLY
for terminal housing replace
ment. If the problem is determined to be in the mo
tor, proceed with
PUMP END DISASSEMBLY,
fol
lowed by
MOTOR DISASSEMBLY
.
The electrical power used to operate
this pump is high enough to cause in
jury or death. Make certain that the con
trol handle
on the control box is in the off
position and locked out, or that the pow
er supply to the control box has been
otherwise cut off and locked out, before
attempting to open or service the pump
assembly. Tag electrical circuits to pre
vent accidental start‐up.
