Broken Koralia impeller shaft

[Tom@HaslettMI]

I just discovered that the ceramic shaft on my Koralia 2 somehow snapped during operation. I'm not exactly sure when it happened but there was a brief power outage today and I suspect it broke when the pump restarted. Does anyone know if a replacement can be purchased (I couldn't find anything on Marinedepot and only a steel one on Premium Aquatics), or if there is a good DIY fix?

Thanks for your help,
Tom

how close to an end did it break?

I'd try Pruess....if they don't have them they can probably put you in touch with one.

That is likely what I'll do. I was just wondering if there were other options since they tend to be $$$.

About 2/3 of the way down from the front.

Mine was still spinning but the magnet on the impeller was not fully seated and there was no flow being produced by the powerhead. If the impeller wasn't spinning I'd venture to guess that the magnet and/or housing is dirty and needs to be cleaned.

okay ill try that!

I had one of mine break just at the point where it sits in the "cap" so I pulled the small section out, and just seated what was left of the shaft into the same spot, works like a charm.

My k 3 broke in the middle, I just put it back in and held the housing during start up and it is working fine. When it quits I will use stainless steel for a replacement. You can get that at any good hardware store or hobby shop and it is cheep.

Thank you everyone for all of the suggestions.


Mine on my K3 snapped when I was cleaning it.... I just threw the shaft out, put the impeller in and it was fine and has been fine ever since with no noticable loss in flow. IMO, save your money ;)

Great suggestion. I tried it and it works but it rattles and makes too much noise.

I wish that were an option but it did not break near the end.

I think the stainless steel route is where I'm headed. Thank you. As long as it is stainless is that all I need to worry about?

Thanks again,

That is what about 1/2 of the pumps and power heads are using.

Email your name, address and phone number to hydor.com along with an explaination of the problem. Their customer support is excellent. They also have a forum over on Nano Reef where they answer questions. Maybe we can get them to sponsor Captive Reefs too?

I have sent email to hydor.com yesterday so we will se how long and if they will contact me.
Hopefully they will sell me a new shaft and ship it to me.
I will let you know what happens.

Thank you and please keep post here when you get word. I would prefer to use a ceramic replacement shaft if possible. For now I cleaned mine and am running it Chort55-style. It still gets off balance once an awhile and rattles but seems to find its way back to center fairly quickly.

WOW!
Well I sent hydor.com a email this weekend and yesterday they sent me a email telling me they would send me a replacement.
I will let you all know when and if it comes.

I told you their Customer Service was fantastic!

Well Well Well, I got home today and found a envelope from hydor. I thought now that is fast from California opened it and they sent me a steel shaft. (darn darn darn) I had told them it was a ceramic shaft when I contacted them, it must be their replacement shafts are stainless steel. But all in all that is great service a free shaft and in a week!
So would I buy another Koralia, YES!
I wish more places stood behind their products.
