PUMP AND SEAL DISASSEMBLY
AND REASSEMBLY
Review all SAFETY information in Section A.
Follow the instructions on all tags, label 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 are keyed to
the sectional views (see Figures 1, 2, 3 and 4) 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.
Many service functions may be performed by
draining the pump and removing the back cover
assembly. If major repair is required, the piping
and/or power source must be disconnected. The
following instructions assume complete disassem­
bly 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.
Do not install a suction check valve in
the first stage of the VS Series pump
model. Installing a suction check valve
in the first stage of the VS Series pump
model can cause over‐pressurization of
the first stage pump casing, resulting in
possible explosion of the pump and se­
rious injury or death to presonnel.
NOTE
The back cover and rotating assemblies are identi­
cal for both the first stage pump and the Ultra Mate
second stage, therefore the service instructions are
the same. Because of these similarities, most of the
following instructions reference the first stage
