Contact us at spasandmore.com if you have any questions about waterway
pumps.
This little guide will help you determine
what model of waterway pump you have.
If the model is PF451N22C that's an Executive
4.5 HP, 1speed w/o air switch, 220volts,
Magnetek motor
We get that by explaining the code used by
waterway.
| SP known as the center discharge, very common
pump on older spas. Not used that much anymore but still a very solid choice for an older or smaller spa. Came in 3/4 up to 2 HP models. Uses the #1000 shaft seal. If you are rebuilding ww pumps don't worry if the impeller breaks off. these use the 1.5" pump unions, very common fitting. |

| BT or bath models are basically the same
exact pump as the center discharge above. Except the front face cover is made differently. The cover design allows the wet end to drain more fully. These are used in whirlpool and jacuzzi type jetted tubs. |

|
| SD or Side Discharge or Hi flo models are
probably the most common spa pump used
at
least in my area and career. It's also very common to see these with the wet end portion rotated 90 degrees to make the plumbing come in lower. You can't go wrong with these pumps. They can be used as generic replacements for most anything out there. The older versions of this pump were more square as seen in the picture on the right. The internals of the old and new are the same in case you still have an old model needing rebuild parts. The shaft seal is the #1000. The impeller will usually not come off when replacing the seal on a older pump. Pay attention to the wear ring on the front of the impeller. Without it you will lose a little pressure. These were made in 3/4 up to 4 hp sizes. |

| PF is the Executive series. very similiar
to the hi-flow but larger and moves
more
water. These come in 48 and 56 frame motor versions. The waterway code does not tell us which you might have so be sure when ordering a replacement. These wet ends come in a 2 and a 2-1/2" suction size. If both of your fittings are the same then you have the 2" If the front fitting is larger then you have the 2-1/2" version. You have to look close to see difference in the front fitting. These use the #1000 shaft seal. They have a wear ring on front of the impeller and it is different on the 4 and 5hp models. made in 48 and 56 frame versions. 48 use the inner mounting holes and 56 the outer on the back of the wet end. |

| TM is the small circulation pump from waterway.
It comes in 2 versions, 1" barbed
and
1" threaded unions. These are pretty decent little pumps for the money. they have a conventional motor and they have a standard mechanical shaft seal that can be replaced. |

|
| This is the waterway Iron mite circulation
pump. It's a s big as a standard jet
pump
although not as long. If you are going thru the little small circulator pumps like laing and grundfos then you need one of these. It will do the job and not over work it. |
