I need to replace the (very noisy, about to seize-up) motor on my Pentair Whisperflo 2HP 2-Speed Pump (Model #WFDS-8, Part #011523).
I very rarely use the low-speed mode because it doesn't generate enough pressure to push around the Jandy Ray-Vac cleaner when the Solar heating is also running (which is just about all the time). The regular 2HP speed mode is plenty adequate for both.
I'm looking at just replacing the motor with an equivalent 2HP SINGLE-Speed motor, like a "Century USQ2012 2HP", an "A.O. Smith-Century B2748 2 HP" or an "Emerson Motors EUSQ2012", etc., but I keep running into something about "48Y Frame" and "Y56Y" Frame. What is this? How do I know they'll fit my existing housing and bolt placements? And Impeller? What else do I need to know??
P.S. I do, at least, know I need a Square Flange and also I'll need a new Shaft Seal.
If anyone can advise me, I'd be most grateful, because (being old, retired, grumpy and cheap) I'd hate to spend $400+ on a new 2-speed when I can do the job for half the price with a Single-Speed.
Thanks so much!
