Should I risk with an old D5 pump?

post #1 of 9
Thread Starter 
One of my friends has 2 old Swiftech D5s in his old watercooling system. They were the first swiftech models without tacho, circa 2005 IIRC. That loop has been sitting in a basement for more than 5 years and he says I can get the pump.

Problem is he mixed copper and aluminium (IIRC) and the fluid or the tubing turned white. Is there a chance those pumps can work? Are they affected by galvanic corrosion?

I don't think he wants to check out if they work any more, and since I'm right now miles away from him, I can't go and check it myself.

The inside of the pumps is stainless steel so is unlikely to be terribly affected by anything. As long as the graphite bearings are not too worn down there shouldn't be a major problem that a good cleaning couldn't fix.

Chances are you'll be putting a new pump top on it anyways, so you'll find out eventually. tongue.gif That and what Jakusonfire said:

I would be less concerned with corrosion and more concerned with the condition of the ceramic bearings.

Sure, I'll be using an EK X-top r2.

How can be the ceramics damaged? Due to use? I don't think those pumps have seen a lot of action. How do I check the condition of the bearings?

The ceramic ball part of the bearing is very hard so it is not the part that gets damaged. It is the graphite socket bearing at the centre of the impeller that gets worn through by the ceramic ball. If it wears through too much the whole impeller will start to touch the wall of the pump at the bottom. Only a very small amount of wear is needed to ruin the impeller so it is quite hard to tell just by looking unless you know what to look for. If the impeller sits on the ceramic ball and turns freely by hand without making any noise or dragging it is fine.

It usually wears through it being ran dry or excessive large air bubbles being ran through it. As for how to check it I think Jakusonfire covered that.

Try it, if it sounds fine it I probably is.

If it makes you feel any better, I'm currently using a D5 pump that was made from March 2006 and used since that year. I bought it used back in Feb. 2012 and it's still running smooth and silent throughout several of my loop/rig upgrades.

This is pretty much what you should be looking out for.
