    Whisperflo Impeller has a mushroom end ??

    All,
    I'm rebuilding / resealing my whisperflo pool pump and after taking the impeller seal off I noticed that the impeller has a mushroom end. It looks like it may have been rubbing on the seal??

    What do you guys think, is this going to be an issue if I just pop a new seal in it ??



    Thanks,
    LarryF_In_So_Cal

    Sorry I don't know Larry, but maybe a bump will get you an answer.

    Since that recess actually seals against the rubber of the seal ring it may leak if you use it. There's only one sure way to know. Put it back together and see if it leaks.

    Get a new seal & gasket set, and new impeller.

    I think that is just the ceramic end of the seal that is stuck to the impeller. You should be able to remove it.

    Re: Whisperflo Impeller has a mushroom end ?? -- Green impeller work?

    All,

    I'm getting ready to re-seal my pump. I have a friend who runs a pool cleaning business and he happened to give me a new impeller.

    I'm wondering if it will work with my pump. I have a Whisperflo WFE-4 with a 1 HP motor. The impeller that I'm replacing is black, the one from my friend is green, and has larger water openings. See picture below.

    Does anyone know what size impeller this is? and can it work with my 1 HP motor?

    what would happen if I were to use it? Could I ruin my motor? And or would the water flow be reduced?

    Please let me know.

    Are there any part numbers stamped on it?

    No, I checked with super strong flashlight as well ad a magnifying glass, There are no visible markings on this impeller. It is however, a greenish tan color.

    Unless it exactly matched the existing impeller, I wouldn't use it.

    You can post a set of complete dimensions and someone may be able to tell you what it actually came off of.
    Outer Diameter
    Hub diameter
    Suction ring ID
    Suction ring OD
    Vane width
    Etc.

    Re: Whisperflo Impeller has a mushroom end ??

    The vane width of the impeller on the left appears to be larger than the one on the right which means it came from a larger pump on a larger motor so would likely overdrive the current motor. The diameters are about the same which means max head is about the same but that is typical for a pump line. Usually, only the smallest pump in the line (3/4 FRHP) has a smaller diameter impeller and a lower maximum head.

    Horizon parts had a tool on their website that told you what impeller it is from the measurements of it.
