Check your Tunze pump for RUST!

[MikeC]

Just a heads up to check your Tunze pumps.
A friend of mine from another forum almost gave up the hobby until he found a very rusted Tunze pump and with in days after removing the problem the whole tank started to recover.

Quote from him:
"Yes, a very rusted Tunze pump... and I got it in April. The rust emanates from somewhere within the magnet housing."

is he referring to return or power heads?

I read a thread on rc about this problem with tunze magnets. I believe they said that tunze went forward using a cheaper magnet which causes this now. Let me see if I find the thread.

From Roger at Tunze when asked about rust on the magnets...

The magnets themselves are ferrite, this is a ceramic material that is man made and can be magnetized, it cannot corrode, this is the same material almost all impeller magnets are made from. These magnets are mounted on an iron plate that is coated by polyurethane, the black filling you see around the magnets. One of two things is happening and just to put you at ease, nothing in these magnets is toxic, their is no nickel, zinc, rare earth elements, etc, just an iron plate, inert plastics and the ferrite magnets.

Ok so this is a quote from the guy with the pump that spoke with them.

"Yeah, I was shocked too. Did not expect it. They are shipping me out a new magnet/pump holder so we will see. I got the "there is nothing in the pump that can hurt a tank" response but I am either looking at it as an flawed/under-spec magnet or that something that is a heavy metal was attracted/left during the manufacturing process."

I'll make it easier for thous who thinks someone is always looking to blame someone.
It is ether a:
1) a flawed/under-spec magnet
2) something that is a heavy metal was attracted/left during the manufacturing process.

I would lean towards something attracted to the magnet, without knowing what was rusting a little hard to say it was the cause.

How many of us use a form of rust, GFO, to remove phosphates?
