Propeller keeps getting stuck on Tunze 9002

[mooch1982]

I have an older Tunze 9002 skimmer, with the old style pump. I have been having problems with it lately. When ever i unplug it, the pump does not start up again. It seems to get stuck. I have cleaned it out wit vinegar, and checked all the parts, and everything seems fine, except I am not sure if the white ring at the end of the shaft should come off, or be fixed to the black magnet in the shaft.

I had to poke the propeller 5 or 6 times to get it to start up again. Everytime, i had to remove the skimmer, remove the pump, and hope it would start up when put back in the water.

I am suspecting the problem is with the shaft, but why would it keep getting stuck?

I do not want to unplug my skimmer in fear of it not starting up again. Any ideas??

There should be a light grey ring that is the base of the magnet, it sounds like that has come off so the magnet can spin without turning the impeller. You need part 0800.042, this is a new impeller. You can order it on tunze.com

Roger,

Thank for the response, but I have the old style pump, and the ring is ON the magnet. Is the ring removal by the way? Because mine comes off, and I am not sure if it is supposed to be fixed. However, like i said I do have the ring on the shaft.

It should be permanetly part of the magnet, the top and bottom ring and the center shaft the impeller mount on are injection molded on the magnet core as one piece, if the base breaks off the shaft is free to move without the magnet so the magnet turns without the impeller.

My ring is broken off the shaft on the bottom, so I ordered the above part. I really hope this fixes the problem.

By the way, will the broken ring affect the skimmer performance even though the impeller is still spinning?

 

[rvitko]

Yes, in this condition the impeller slips occasionally so the flow and pressure are lower.

Hey Roger,

Received the propeller today, but one problem. I think it is the wrong one. The top portion of the propeller, or the blue plastic cap has a hole in it. The propeller I have does not have a hole in it, but is sealed. The rod can fall right through the new propeller because of the hole in the top blue cap.

Please advise.

 

[rvitko]

The shaft should be firmly imbedded in the pump itself and not at risk for coming out, if it is coming out push it down hard into the socket in the pump, the hole was a later revision to increase cooling and should not affect the pump operation.

Got it!

Thank you so much Roger. Excellent customer service.
