Alu/Cu Galvanic Corrosion - nude pics included! :)

Hi all!
I saw in the other thread that there's interest in seeing pics of water-block corrosion. I lost my account from 5years ago... so i made this one to post this.
If not properly cared for... i.e. using tap water, foreign contaminants, etc. this CAN happen to you!!
I've since stopped using Alu and Tap-water in my loop!

That look nasty :0

Learning sequence !

Thanks, always nice to have more proof.

Ok guys whats for dinner?

Yeah, some good closeup pics of what happens with a mixed metal loop with no anti-corrosives in it. What block is that, an old Whitewater? The inside of it looks like the old DD RBX I used to have, which I heard was almost a direct copy of the WW.

Man, what a mess ... ... now saved for posterity!

Heya! sorry I'm in the middle of my tear-down, CLEANING... then rebuilding my loop that's been running for aprox. 5yrs!!!! Swiftech Storm,mcw30,mcw60,mcp350,mcp655. All-in-all.... not bad inside.... considering a sponge i tried to use in my resevoir as a filter...started to disenegrate before i removed the piece of crap!!

Yes! that was/is my old D-tek Whitewater... i got it soon as Cathar/Dtek released it in the U.S. I think the Acrylic top WW was offered @The time...I thought Alu Top would be more durable/not crack...ehh learning experience! lol
Yeah the RBX came out after it... 6mnth - 1yr later? always thought the RBX was a cool block!

Bonus image! a side benefit of being fouled with... a slurry! lol I found the middle-plate quite... "interesting"

That is interesting. It looks like there might have been some bleed-over between outgoing and incoming. It also seems the jets kept themselves pretty clean, considering.


Edit:
Or are you hinting about it being the original design instead of an R2 ...?

Money!

Ding Ding! your first guess is right on the $Money$! The slurry provided a nice visual indicator of the bleed-thru as you said. A groove and O-ring would be a nice mod, but i'm moving onto an Apogee XT.. yay!

P.S. Do you know anything about Laing D5/MCP655's?
Half-way down the page you'll see an opened rear of a mcp655. "D5 RPM mod link"

If you look at the naked behind of the pump(perv!)lol you'll see a huge capacitor? across the back of the rotor-tub! which my 655 Does Not have!!?? My guess is that i cannot do the RPM wire mod to my pump.

So... what's with my revision? what's the differences between my 655 and current ones?

My neked pump....


Thanks for any help you can provide!
