| 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! |
