Mag 3/5 Air Fractionating Impellers

[MolaMola]

Anybody have a use for these? I got two by mistake at some point. For Danner/Pondmaster Mag Drive 3 & 5 pumps. Note they are not normal impellers.

In Pleasant Hill or I can bring to swap.

Vintage!
Do you happen to have the Venturi nozzle attachment too?

No, I don’t need them

I was hoping they were a pond thing bc I don't see how they work for the pump.
