    Pump Suggestion for 33k Gallon Pool w/Sand Filter - Replacing Pentair WhisperFlo

    So my Pentair Whisperflo WFE-3 - 3/4 HP pump has quit working, new capacitor does not work, when I turn it manually via that nut on the end nothing happens. The external metal housing of the unit is also completely corroded and has turned to powder, so a rebuild probably wouldn't be worth it at this point.

    I am looking for suggestions on a high quality, long lasting pump that saves energy. I have been reading and looking and am pretty thoroughly overwhelmed by the options.

    I have a Polaris 380 Pool Cleaner with the extra pump, so unsure if this makes a difference on the type of pump to get.

    Any pump advice and/or suggestions would be appreciated.

    33,000 gallon, chlorine (3" tabs + liquid shock), Vinyl Liner Pool.

    Thanks!

    I think I mentioned this on your other thread but you could just replace the current motor with a new two speed motor and save quite a bit of money. B2980

    I'm leaning more towards that, as I could get that 2 speed motor for less than $300 by reusing that skimmer housing part. It seems pretty easy as well according to that video. So is it really a 30 minute job basically?

    Yes for the most part it is pretty easy. It gets difficult when the bolts are rusted or the impeller won't come off the old motor but a strap wrench helps with that. You also need a go-kit
