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 1) and the accompa
nying parts list.
This manual will alert personnel to
known procedures which require spe
cial attention, to those which could
damage equipment, and to those which
could be dangerous to personnel.
How
ever, this manual cannot possibly antici
pate and provide detailed instructions
and precautions for every situation that
might occur during maintenance of the
unit. Therefore, it is the responsibility of
the owner/maintenance personnel to
ensure that only safe, established main
tenance procedures are used, and that
any procedures not addressed in this
manual are performed only after estab
lishing that neither personal safety nor
pump integrity are compromised by
such practices.
Before attempting to service the pump, disconnect
the incoming power to the motor and lock it out to
ensure that the pump will remain inoperative.
Close all valves in the suction and discharge lines.
For motor disassembly and repair, consult the liter
ature supplied with the motor, or contact your local
motor representative.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man
ual.
2. Disconnect the incoming power to
the motor and lock it out to ensure
that the pump will remain inopera
tive.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature before
opening any covers, plates, or
plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau
tiously.
7. Drain 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. 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.
Be certain proper safety practices are
followed before operating or servicing
the pump. Provide adequate ventilation,
