How to clean a Tunze pump and what to do about a driver alarm.

Roger

Just bought a used wavebox(6260.10 pump) and when I plugged it in it did not work and transformer and driver got very hot immediately. No driver alarm sounded. Took pump apart and cleaned(extensive calcium deposits present). Swapped out driver(7240.27) with my 6200 and wavebox worked for two hours then driver alarm sounded. Recleaned pump and driver alarm again sounded within 5 minutes. Took drive unit and bushings from the 6200 and put them in the wavebox 6260.10 and alarm again sounded within five minutes although pump was functioning. When I put the driver and drive unit back on the 6200 they work fine. What do you suggest I do?
 
Send in the pump and driver and I will call you and let you know what we find and how much it will cost to repair. I suspect the pump is bad or there is some small drive unit issue, like a mismatched bushing or bearing.

Roger:

I am looking for an owners manual for some old 6100.10 s
( I have 5 of them) I cannot find them on the website....can you tell me if they may be archived somewhere that I could download a copy?
Thanks,

Hi Roger ,
I am having the same problem as a post I just read by Jmaxwell
Roger,

I've got a 6101 (a pair actually) and I think the motor is dead. Its about 9 months old, and I just cleaned the whole thing. All four parts of the impeller (impeller, bushing, o-ring and the other thing that is a pain to get out w/o needlenose pliers.) look free of calcium as does the hole that the impeller goes into. I usualy run it on a 7095, but I've been testing it in a bucket of water and just pluging it into the wall sans controller. The pump does nothing, no sound or anything. The little fuse looking thing that is set to 24V at the top glows red. Is that correct? I don't know that I ever heard any "alarm" where would I see that? Anyway should I send it in? I'm pretty sure I can not find my receipt.


although I have not taken the impeller apart it looks real clean to me and the other two older 6100 are working fine .
what do you sagest I do?
thanks

6101's don't have an alarm, that is the older 6100. It is rare but sometimes a power supply lights up but doesn't work, I would try another power supply from a working pump.
 
Send them in, if I can't repair them I will replace them, please include the power supplies.

I'm trying to take the impeller out of my 6100 for maintenance but it simply won't come out. I tried leaving it in white vinegar over night but it's still stuck in there solid.

This isn't the first time I've had to do maintenance on the pump but this is the first time I've been unable to extract the impeller.

Looking at the 3rd picture posted on the first page of this thread, I have the 3 parts at the far right removed from the assembly, but the rest remains stuck inside the body of the pump.

Any suggestions on extraction?

Please advise.

Thanks,
Chris
 
Hi Roger
just checking in with you to see if you had time to look at my two pumps yet .
thanks
Frank
 
Chris,

If you can't get them out easily it is best to send the pumps in, usually the stuck parts will be destroyed in the removal process and you will need new ones. They typically have to be drilled out in these cases, but sometimes I can extract them with a dent puller (slide hammer), but they still are ruined.
 
Thanks Roger. In that case, I'll order a new one and try to yank the old one out. If I'm unsuccessful or feel I'm putting too much stress on the unit in the attempt, I'll send it to you.

Out of curiosity, are the new impeller units any less likely to get stuck like this than the older style?
 
It depends how old, over the last 7 years we made several incremental changes aimed at reducing the heat and vacuum inside the pump that causes calcium to precipitate but the most important thing is to be thorough when you do your cleanings and never use any acid stronger than 5% vinegar. Strong acids cause the plastic to swell permanently from hydrogen bonds so the spaces become tighter and the pumps run hotter, same for any calcium deposits left in the upper bearing and center cooling port in the magnet.
 
Hi Roger i just set up the 6105 and one of the power supply is not working
I chaged out the jumper from 24 v to 18 v and bolth lights are on
what should I do ?
thanks for your hepl
Frank
 
Roger I did a search on my problem and found that even with the red light on you can have the jumper not in right.
so every thing is working perfect and I am very happy with your customer service
tunze are the best :)
