PUMP AND SEAL DISASSEMBLY
AND REASSEMBLY
Review all Safety information in Section A.
Follow the instructions on all tags, label and de-
cals 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 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.
Before attempting to service the pump, disconnect
the power source or take other precautions to en-
sure that it will remain inoperative. Close all valves
in the suction and discharge lines.
For power source disassembly and repair, consult
the literature supplied with the power source, or
contact your local power source representative.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man-
ual.
2. Disconnect or lock out the power
source to ensure that the pump will
remain inoperative.
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.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam-
age to equipment.
Suction Head Removal
Remove the suction and discharge piping. Before
attempting to service the pump, remove the pump
casing drain plug (38) and drain the pump. Clean
and reinstall the drain plug.
For access to the impeller (2) and seal assembly
(3), the suction head (39) must be separated from
the pump casing (1). Remove the nuts (47), and
pull the suction head and wear ring (40) from the
pump casing. Remove the suction head gasket
(48).
Tie and tag any leveling shims used under the suc-
tion head and pedestal mounting feet to ease reas-
sembly.
Use caution not to damage the suction
head when removing the wear ring.
Inspect the wear ring (40) for excessive wear or
damage. The wear ring is secured in the suction
head by a press fit. If replacement is required, use
a small bit to drill three holes horizontally through
the ring, 120
_ apart. Use a chisel or other suitable
tool to complete the cuts through the ring and re-
move the ring from the suction head. Be careful
not to damage the bore when removing the ring.
