Replacing a motor on a pump, and getting the correct size for your pool?

[mas985]

If I went with the SQS1072R, would I need a new impeller and/or diffuser? What about with the UQS1102R or HSQ125?

HSQ125 may be an issue because of the back end. I can't guarantee that would fit on the motor support.

As for the impeller, it depends on the service factor of your current pump motor. If the current service factor is 1.25 or lower, then the impeller is fine. Diffuser would not change either way.

According to the label on the current pump, it's a USQ1102 equivalent, with a SF of 1.25.

Thanks for all the help! I think I'm going to get or order the SQS1072 after checking with my local pool warehouse.

Am I understanding this right... could this be used to program when the pump is on while also putting a timer on when the pump is switched to a certain speed? Would the main on/off timer feed the switch that determines when the pump is on full speed? That's the sort of thing I'd find handy to have, with manual overrides (if possible.)

Never mind the previous post. I found the wiring diagram on how it works.
