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 10) and
the accompanying 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, shut down
the engine and take precautions to ensure that the
pump will remain inoperative. Close all valves in the
suction and discharge 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 postiive 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.
No instructions are provided in this manual
for disassembly and/or removal of the
pump enclosure. If removal of the enclo­
sure is required for pump service, be sure
to use safe shop practices so as not to en­
danger personnel, and use caution to pre­
vent damage to the enclosure.
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi­
cient capacity and that they are posi­
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Suction and dis­
charge hoses and piping must be re­
moved from the pump before lifting. Lift
the pump or component only as high as
necessary and keep personnel away
from suspended objects.
