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 views (see Figures 1 and 2) and the
accompanying 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.
Many service functions may be performed by
draining the pump and removing the back cover
assembly. If major repair is required, the piping
and/or power source must be disconnected. The
following instructions assume complete disassem-
bly is required.
Before attempting to service the pump, disconnect
or lock out the power source and take precautions
to ensure 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 Check Valve Removal
(Figure 1)
If the check valve assembly (24) is to be serviced,
disengage the hardware (9 and 26) and remove
the check valve cover (25). Pull the check valve as-
sembly from the slot in the pump casing (1).
Back Cover And Wear Plate Removal
(Figure 1)
The wear plate (7) is easily accessible and may be
serviced by removing the back cover assembly
(12). Before attempting to service the pump, re-
move the pump casing drain plug (6) and drain the
pump. Clean and reinstall the drain plug.
Remove the back cover nuts (16) and pry the back
cover and assembled wear plate from the pump
casing (1).
