Note that the purpose of this section is to show you how to remove
& install a Sta-Rite® P2R Series Pool and Spa pump motor and seal
kit. 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.
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 Sta-Rite
Duraglas® pool pump. There are three versions of seals/seal kits
available. The most inexpensive is the #200 seal set, show below. The most extensive
kit available from Sta-Rite Industries is a complete rebuild kit, containing all components
internal to the wet end.

After Removing power from the unit, The first thing
that must be done is to remove the securing band around the pump. This simply unscrews
counter-clockwise.
|
|
|
With the clamp nut removed, the band must be removed,
carefully that is, taking care not to put any kinks or bends in the stainless steel band itself.
|
|
|
The Sta-Rite pump is designed to be split from the suction and discharge plate,
without having to disturb the plumbing.

Here, I have to disconnect the power wires and the
conduit from the back of the motor. In this installation, I have removed the pump first, sat it in
my lap to prevent damage to the diffuser, and then worked on the wiring. Depending on the
installation, this can be accomplished as the first step instead of the second.
|
 |
|
Since I've got the pump in my lap already, after I
removed the wiring, I just flipped it over and removed the diffuser.

After putting the pump on a suitable work surface,
comes the interesting part. In order to remove the impeller, the back of the motor armature MUST be
stopped from rotating. Note that this procedure will not apply to your motor if you have the larger
56 frame version. In that case, you stop the rotation of the armature with a pair of vice grips
through the access hole in the back, or the special tool designed by the motor manufacturer.
In this case, we have an
uprated 48 frame style motor. The ONLY safe way to do this, without destroying the spring loaded
centrifugal switching mechanism, is to line up a large screwdriver flat along the side of the
spring mechanism attached to the armature, an then the anchor point at the top rim of the motor.
The left image shows the screwdriver properly inserted into position, the right shows the line
up... the arrow points to the top anchor point. Your motor may or may not be like this, so you must
use common sense.
|
 |
|
|
Here you can see the screwdriver lined up from the front.
|
|
Removing the impeller is usually easy at this point, I
simply grab the front of it, and rotate it counter clockwise. Note that some versions of Sta-Rite
pumps have a center screw in the impeller which must be removed first. If so, remember that this
screw is LEFT-HAND threaded!
