I have a few pieces from a kaput Sedra 3500 skimmer pump available.
From Left to right:
Magnet and needle wheel. Magnet is fairly scratched but may still work. I'm throwing this in for free.
Volute and venturi.
Needle wheel. Has a few broken needles. Might make a good mesh-mod.
Full impeller setup. Was running in the pump when it started throwing stray voltage, but was also starting to get stuck. I'm not sure if the sticking was due to the impeller, the pump, or both.
Just over 6 feet (single piece) of the airline tubing that fits the air intake of the volute (or is it the venturi?) (Not pictured)
$10 for all of it. I'd also consider a trade... what-cha got?
