PUMP DISASSEMBLY AND
REASSEMBLY
Review all SAFETY information in Section A.
Follow the instructions on all tags, labels and
decals 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, unless
otherwise specified, are keyed to the sectional
view (see Figure E‐1) and the accompanying parts
key. Refer to the separate parts list accompanying
your pump for part numbers.
In the following text, minor headings are followed
by a number in parenthesis. This number repre
sents the assembly for the item being discussed as
identified in Figure E‐1.
Before attempting to service the pump, shutdown
incoming power and lock it out or disconnect the
power source to ensure that it will remain inopera
tive.
For power source disassembly and repair, consult
the literature supplied with the power source, or
contact your local power source representative.
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 pro
vide detailed instructions and precau
tions for each specific application or for
every situation that might occur during
maintenance of the unit. Therefore, it is
the responsibility of the owner, installer
and/or maintenance personnel to en
sure that applications and/or mainte
nance procedures not addressed in this
manual are performed only after estab
lishing that neither personal safety nor
pump integrity are compromised by
such applications or procedures.
Do not attempt to service the pump un
less all power to the power source has
been disconnected; otherwise, serious
personal injury or death could result.

ports. Disconnect the suction and discharge hose/
piping.
Remove the hardware securing the pump to the
power source and separate the power source and
pump assembly. Retain all connection parts such
as shaft keys, etc.
Use a hoist and sling with sufficient capacity to
position the pump in a suitably sized drain pan or
surround the pump with absorbant material. Some
