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 views (see Figures E‐1 and E‐2) and
the accompanying parts lists.
As described on the following pages, this manual
will alert personnel to known procedures which re­
quire special attention, to those which could dam­
age equipment, and to those which could be dan­
gerous to personnel. However, this manual cannot
possibly anticipate and provide detailed precau­
tions for every situation that might occur during
maintenance of the unit. Therefore, it is the respon­
sibility of the owner/maintenance personnel to en­
sure that only safe, established maintenance pro­
cedures are used, and that any procedures not ad­
dressed in this manual are performed only after es­
tablishing that neither personal safety nor pump in­
tegrity are compromised by such practices.
Many service functions may be performed by
draining the pump and removing the suction head.
If major repair is required, the piping and/or engine
must be disconnected. The following instructions
assume complete disassembly 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 and dis­
charge hoses and piping must be re­
moved from the pump before lifting.
Cleanout Access And Suction Check Valve
Removal
(Figure E‐1)
Before attempting to service the pump, remove the
casing drain plug (41) and drain the pump. Clean
and reinstall the drain plug.
For cleanout access, loosen the clamp screws (15)
and clamp bars (13) securing the cleanout cover
(16) to the suction head (49).
To remove the check valve assembly, reach
through the cleanout opening and remove the
hardware (8, 9 and 10) securing the check valve (6)
to the valve body (4) and suction head.
