Magnet Mount Strength & Options

[new2u]

I have loved Tunze pumps for years and have an interesting question regarding the magnet mounts that are now standard on all your pumps.

I am looking at using 4 6105 pumps in a 240 (6 x 2.5 x 2) and possibly putting 2 on the back glass and 2 inside of rocks in the lower left & right corners.

The issue I have is that due to some complicated medical issues (Brain Surgery x 3 & a magnet controlled shunt in my neck) I now need to avoid strong magnetic fields to avoid accidentally changing the setting in my shunt. Can you provide any addtional specs on the specific strength & materials of the mounts?

Also, are they removable in any way? If I were able to take them off and use some sort of different mounting method (I was hoping to do this in the 2 in the rocks at a minimum) that would solve all my problems.

Thanks!

They do come with a magnet holder and it is quite strong, the manual specifically warns they are dangerous around pacemakers and medical devices. I know they are a rare earth magnet and I believe they are rated to hold 20 kilos, about 45 lbs. You could omit them but someone else should remove them from the packaging. You could instead use the Stream Rocks, or you could use the older rail set 3000.250 with the 6080.520 clamp.

Thank you for your quick response Roger. That is great news that they are removable. Would you suggest using 2 rocks and 2 clips for a 240 or would you mount them all on rails?

From what I can tell from your site the rails/clamps are only up to .47" thick and the tank will be .5". I'm thinking since I have dual overflows I could mount them there instead, but would it be an issue for both sides to be wet?

PS these are the right product links right?

The clamp 3000.250 only one end goes in the tank, it clamps at the top very similar to a woodworking vise. It can span .74", with 3000.244 screw set that can be extended to about 2" (longer screws).

The listings are correct.

The clamp 6080.520 description is wrong, it looks like the info was cut and paste from another description, it slides onto 3000.250 and the thickness of glass is irrelevant to this part.

Really old thread here, but I am finally getting the tank setup this week and have been putting together the mounting hardware. As a reminder I am using

-4 6105s
-2 stream rocks
-1 7096 Multicontroller
-2 Older rail set mounting

First question is about placement of pumps on rails. Is it ok to put them on the back glass in the corners and angle them to the center? With the older rails I was thinking they would ruin the look of the rimless tank if they were on the sides.

My second question is about the placement of the stream rocks. With the stream rocks do I need to put something below them to keep them off the sand bed? Should I mount them on top of other rocks so they don't have issues with the sandbed?

My final question is about the programming for the 7096 mulicontroller. Do you have any suggested patterns for initial use with this sort of setup? I have the software it was bundled with and work as a programmer so I am not too worried about getting it set up but I could use some tips on patterns to try.

Thank you so much!

1) Yes, that is fine, the best would generally be back wall in a corner aimed to hit the front 2/3rds of the way down the tank.

2) Yes, you want to have them high enough they cannot take in sand.


3) I generally recommend interval mode with idle speed and a 6 hour interval pulsing pumps 30-100% every 3 seconds.

Roger, I meant to call you today but I ran out of time.

We ran into some difficulty getting the brackets installed, and we have used the magnets as a short term solution. Do you think it would be possible to see any pictures of the assembled kit? A lot of old threads reference your gallery but I can't find the old photos.

Are there any tips you have for their installation?

 

[rvitko]

Can you get me a picture of what you are trying to mount to?

 

[new2u]

Yes, i can get that to you this evening.

It is a rimless tank, so it is just 3/4 glass.

 

[rvitko]

The rail should do fine for that, maybe this picture helps?
