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 1 through 7) 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.
Before attempting to service the pump, switch off
the engine ignition and disconnect the positive bat-
tery cable to ensure that the pump will remain inop-
erative. Close all valves in the suction and dis-
charge lines.
For engine disassembly and repair, consult the lit-
erature supplied with the engine, or contact your
local engine representative.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man-
ual.
2. Shut down the engine and discon-
nect the positive battery cable 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.
This pump may be used to handle mate-
rials which could cause illness through
direct exposure or emitted fumes. Wear
adequate protective clothing when
working on the pump or piping.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam-
age to equipment. If slings or chains are
used to move the pump or components,
make sure that the load is balanced;
otherwise serious personal injury or
death could result. Suction and dis-
charge hoses and piping must be re-
moved from the pump before lifting.
This pump is equipped with automatic
liquid level controls, and is subject to
automatic restart. Keep hands and
clothing away from the unit to prevent
injury during automatic operation. Dis-
connect the positive battery cable be-
fore performing any maintenance. Fail-
ure to do so may result in serious per-
sonal injury.
