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 E−1) and the ac-
companying 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
or lock out the power source to ensure that the
pump 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.
Suction Plate And Wear Ring Removal
Before attempting to service the pump, remove the
casing drain plug (43) and drain the pump. Clean
and re-install the drain plug.
Disconnect the suction and discharge piping.
Install an S" hook in one of the mounting holes in
the suction plate (49) and support the suction plate
(49) using a suitable hoist and sling. Using a pair of
pry bars, carefully pry the suction plate out of the
bore of the wear ring (47). Inspect the suction plate
O-ring ring (48) and replace it as required.
Disengage the hex nuts (58) securing the wear ring
(47) to the pump casing (1).
NOTE
No provisions are made for supporting the wear
ring during removal or installation. The studs (59)
are of sufficeint length to allow the wear ring to be
removed from the pump casing bore and still be
supported on the studs. However, use caution
when removing the wear ring as described in the
following step in order to prevent the wear ring from
being dropped or damaged.
Using a pair of pry bars, carefully pry the wear ring
out of the pump casing bore. Inspect wear ring for
excessive wear or scoring and replace it as re-
quired. Inspect the O-ring (44) and replace it as re-
quired.
If no further disassembly is required, see Suction
Plate and Wear Ring Installation.
