Note that the purpose of this section is to
show you how to remove & install a spa pump seal for an
Aqua-Flo® FMHP style spa pump. While every
effort is made to be sure that virtually all areas of complexity are covered,
you may find it more difficult or sometimes easier to accomplish this
task. Use common sense. If the pump that you have on your pool or
spa is a lot different from what is depicted here, then do not use these
instructions. This is page 2 of this procedure.
Safety Warnings!
| Remove Power from the spa/hot tub BEFORE performing this
procedure. Failure to comply with this requirement, can lead to
electrical shock and/or electrocution! |
Disclaimer
|
| The
instructions here are intended for general reference only. Many pumps
are different from the one depicted here, and may require more or less
mechanical effort or knowledge in order to achieve the desired
results. |

This example of pump seal replacement is on a
Aqua-Flo® FMHP style spa pump. An FMCP style is virtually
identical. In years prior to 1987, a 5 piece pump seal was
used. In this sequence only a 3 piece version is installed. The
installation sequences are quite similar. This is page 2 of this
procedure.

| Hopefully, your old impeller
will be reuseable. |
|
| Simply slide off the old pump
seal. |
|
|
 |
 |
| Using a flat head screwdriver
I carefully pry the old ceramic seal and rubber seating cup out of the back
part of the wet end. |
|
| Since there was a lot of rust
on the shaft, I clean it off as best as I can, and then coat it with Waterlube,
anti-corrosion lubricant, (arrow). If the rust is really bad, I'd go
ahead and remove the wet end from the motor and sand the pump shaft down with
sand paper or emery cloth... then reassemble it. |
|
|
 |
| Next I simply press the new
ceramic seal and rubber seating cup into the wet end socket. Never put
any kind of libricant in this socket... the seal could spin and destroy
itself. If it's difficult to push in, wet the rubber with water, and use
both thumbs to press it in place. |
|
|
 |
 |
| Now getting the
spring loaded seal on the impeller can be difficult. In most cases you
will have to use both sets of fingers to squeeze it over the impeller
shaft. Again, do not use any lubricant other than water to slide it on,
and be sure that the shiny black part will end up facing the ceramic seal when
the impeller is re-installed on the armature.. |
