Upgrading to Variable Speed Motor/Pump

So i’m a litle confused as to upgrading to a Variable Speed Motor/Pump.

I have an existing Single Speed Motor/Pump & live in California.

My Motor went bad … am i supposed to upgrade the Motor AND Pump even though the Pump is good?

Can you just upgrade to a Variable Speed Motor with my existing Pump? … or do i need a Single Speed Motor to replace the existing Motor since Pump is ok?

Thx for clarifying

Hello Jonny - You can replace the motor and keep the existing pump. We can recommend the correct variable speed motor if you provide the make and model of your pump.

But do i replace Motor with another Single Speed, or a Variable Speed?

Thx!

You would replace it with a variable speed motor.

I apologize, i did not see that you mention a Variable Speed Motor in 1st response. Thank you for your help.

You’re welcome. Good luck!

Yes, maybe you can confirm correct Variable Speed Motor…

My Pump is a Pentair “Whisper Flo” WFE-4 , 1 HP, 1.65 SF

Current Motor is a Century/OA Smith 56Y, 1 HP, 1.65 SF ( square flange )

I believe the correct Variable Speed Motor would be your AO Smith #**ECM16SQU ,**correct?

So nother’ dumb question … if you are mating a new Variable Speed Motor with an old Single Speed Pump, do you get the same savings on electrical usage? … or are we just doing it because the CA Law wants me too?

Thx!

Yes, model ECM16SQU would be the correct variable speed motor. You can save up to 80% on your electrical consumption by switching to the variable speed motor. You reap the most benefits when you run the pump longer on a lower speed.

We recommend replacing the seals when you replace the motor. The seal kit for the Whisperflo is GOKIT32. Use GOKIT32SALT if you have salt water.
