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 illustrations (see Figures 1 through 6) and the
corresponding parts lists. Instructions for the air
compressor are covered separately in specific liter
ature available from the manufacturer.
Some pump service functions may be performed
without separating the pump end assembly from
the power source. However, the priming chamber
(31, Figure 1) and discharge check valve assembly
(33, Figure 1) must be removed to service most
pump components. The following instructions as
sume complete disassembly of the pump is re
quired.
Before attempting to service the pump, lock out or
disconnect the power source and take precautions
to ensure that it will remain inoperative. Close all
valves in the suction and discharge lines and drain
the pump casing by removing the lowermost pipe
plug (3, Figure 2). Clean and reinstall the pipe plug.
This manual will alert personnel to
known procedures which require spe
cial attention, to those which could
damage equipment, and to those which
could be dangerous to personnel.
How
ever, this manual cannot possibly antici
pate and provide detailed instructions
and precautions for every situation that
might occur during maintenance of the
unit. Therefore, it is the responsibility of
the owner/maintenance personnel to
ensure that only safe, established main
tenance procedures are used, and that
any procedures not addressed in this
manual are performed only after estab
lishing that neither personal safety nor
pump integrity are compromised by
such practices.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man
ual.
2. Lock out or disconnect the power
source to ensure that the pump will
remain inoperative.
3. Allow the pump to completely cool
if overheated.
4. Check the temperature and make
sure it is cool before opening any
covers, plates, gauges, or plugs.
5. Close the suction and discharge
valves.
6. Vent the pump slowly and cau
tiously.
7. Drain the pump.
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.
