Tunze 6025 stopping

[gawf4fun]

I've got a 6025 which seems to be stopping intermittantly for no partiuclar reason. Over the last 3 weeks or so, I've come home and found it stopped at least four times.

I open it and there's no clogs or other visible issues. I then flick the impeller with my finger and it starts right up, put the cover on and return it to it's holder.

Does anyone else have this problem? Is there an age consideration where they start to do this? I've had this one running for nearly 2 years I'd guess.

This really irks me as the function of this powerhead is to agitate my water surface as I have a single overflow covering a large surface area and I get accumulations of surface "gunk" when it's not keeping the water agitated.

Thanks to anyone who had suggestions, comments, etc.

it probably just needs a good vinegar bath. Let it soak in half vinegar and half water for several hours to break loose any deposits on the shaft. If you use 2 part, it will make any pump jam quick.

Check that the metal shaft is not broken and is firmly in the pump, we changed from a stainless steel shaft to a titanium alloy shaft about 2.5 years ago and the older stainless steel shaft could break. If the shaft is OK, then the drive unit and disk have worn out, we changed these parts a little less than two years ago to a carbon fiber reinforced plastic to solve this problem. Let me know, if it is just the disk and drive unit we can send them. If the shaft is broken, they need to be sent in.

Hi Roger,

The shaft is fine and firmly in place. I've sent you PM with address details, etc.
