converting a single speed pump to two speed.....

[Robins Airman]

Is it possible? my pool pump seized up during the winter and I had to replace it...bought one on line and I some how ended up with a one speed 1.5 HP Waterway pump. while installing it I noticed that the power cord would not reach the timer. I decided to take the cord off the old one and replace the new one's...when I removed the back cover to the pump I noticed that the new pump appears to have the same electrical connections and the old two speed pump...the only difference seemed to be the wiring connections and the two way switch. The electrical posts were even numbered the same,

What do you all think? is this doable?

Thanks in advance for your help...Bo

Three way switch on old pump:

Two way switch on new pump:

You would need to replace the motor to get a two speed pump. The electrical connection panel is the same, but the motor windings are done differently on a two speed motor.

If the motor is not a 2-speed motor ... no amount of "fancy" wiring is going to result in have a low and high speed. The motors are built differently with separate windings for the 2 speeds.

What does the placard on the side of the new motor say?

Thanks for you help...kindda figured that would be you all's answer...though not what I wanted to hear...figured it was possible since the wiring connections looked the same but not used because it only had a two way switch...anyway, here are pics of the placard...please let me know if you change you mind.

Thanks...Bo

It only lists 1 RPM (3450) and 12 amps ... it is a single speed motor.

That is a single speed motor. There isn't any changing that without replacing the motor.

dang!!! i don't know how i missed the fact that it was a single speed pump when i bought it......

Thanks fellas.
