The old single speed motor is dead. I would like to replace the failed motor with a two-speed motor.
WhisperFlo WFEDS-8C attached with A.O.Smith SQ1152 48Y 1.5HP 230V
I was told, the WhisperFlo pump was originally designed for a 2-speed 2 HP full-rated pump. I should replace the motor with AOSmith B2984.
My questions are:
1) Can I use Emerson EB984? both brands have same output, but look different, I guess different working mechanisms
2) If both motors fit to the pump, which brand is more durable?
3) According to the whisperflo pump curves, 1.5/0.19 HP pump has fairly comparable performence with 2/0.25HP pump. What is the drawback if I use 1.5/0.19HP motor instead of the supposed 2/0.25HP motor?
