100,000 hour pump!
 

Today, was the first sampling of our 2500 hour test using our newly developed sapphire on sapphire bearing system (patent pending), for liquid cooling pumps.

Running at 150% of typical load, todays results show a bearing life in the 100,000 hour range.

Testing program will continue, as wear at this point is very difficult to measure, and we need more time and sampling for final predictions.

If this technology is proven, we expect a major increase in pump warranty periods.

Not do be an ass, but wasnt the first original C-Systems pump MOTOR rated for 50,000 MTBF? Even still there were plenty of problems with that pump. Interested to see full results of this new one though.

Yes, the first motor was. This is a rating of the whole pump. How has the experience with the original MAG been?

So far, it seems that users have had a very positive experience with the new mag, though I should note that I am yet to get one for myself. Having a 100,000hr rating would be great, even if it is overkill.

How is it possible to "overkill" on pump life expectancy?

I think that C-Systems have improved leaps and bounds, and have shown a positive effort to listen to users and improve their pumps. This can only be a good thing for all.

While a 100000hr MTBF does not necessarily equate to a 100000hr life-span, it certainly spells volumes for the increased quality of manufacture.

thanks for your efforts dave. I think that the mag is a definite improvement over a great pump that had tremendous potential.
I have not a single complaint about my mags.

again thanks

i'm happy to hear this. reassures me that i've made a good investment. will there be a possible warranty extension then?

What does it mean then? :confused:

The only reason that I say that 100K hours is overkill is beacuse of the fact that I doubt I'd still be using the same pump/system :D .

Is 100,000 hours overkill?

Well first I must say, I don't believe many people on this board know the current and future applications for the MAG style pump.

Wish I could say more, only be assure we have a customer that requires an 80,000 hour rating overall.

The real advantage of this bearing system comes in fluid that can be used, and the resistance to bio issues.

As an engineer, this finding is very promissing :)

I think it's great news Dave. I personally do not scoff at tech advancements, even if they do not directly impact me. :rolleyes:

I should also state, this bearing system produces less noise at 6000 rpm, then current system at 2400 rpm.

Not that there is much noise to begin with, but still an interesting feature?

So are you going to offer pumps with revised electronics for higher pressure/flow (higher rpm)?

Would be interested in seeing a 3500rpm pump of the same design if the impeller is the same as the MAG and 2400rpm was the old rpm.

Beyond "interesting". :)

MAG impeller design seems to me like "state-of-art" on mechanical design: light weight, strong magnetic force, high performance and balance accuracy.

With that new saphire-saphire shaft-bearing i think we will get more flow X pressure at same noise and vibration.

congrats, Dave.

"So are you going to offer pumps with revised electronics for higher pressure/flow (higher rpm)?"

OEM only so far Stew, however we have a new impeller / magnetic / chamber combo that Dan thinks will be safe against "pump hackers", as he calls them.

The idea is that increasing port or chamber size will a decrease in flow / pressure with this configuration. He has asked me to test it, and I am still awaiting machine time.

As I am sure you know, higher pressure will be at a costs of lower zero head flow.

If I read correct, your only looking for 1 GPM on your new blocks?

I just saw the 6000rpm thing, and wondered if that meant that there was going to be a higher specced model being released.

My interests in pumps extends to a "theoretical" one-size-fits-all scenarios "perfect" pump, which has the following characteristics:

6-7mH2O peak pressure head
13-14LPM peak flow rate
20W operational power draw under moderate pressure resistance
compact (fits within 10x10x10cm bounding box)
quiet (~25dBA or ~Papst4412FGL noise level at most)
12VDC power input.

Right now I'm using an Iwaki RD-30 @ 17v to approximate that.

This is not specific to my blocks. This was a set of specifications that was arrived at by carefully considering the lowest achievable temperatures across a broad range of waterblocks (highly restrictive to low restriction, and including additional GPU blocks) and radiators by factoring in the pumping power vs pumping heat dump into the liquid vs "typical" CPU heat load.

i.e. just an intense desire to see such a waterblock agnostic pump be made.

"fits within 10x10x10cm bounding box"

There no problem to meet your flow and head requirements, given this amount of space. A larger pump based off MAG design would exceed these numbers.


Send us a check for $XXXXX and we will tool one for you :)

**just banged on the calculator, can do this with a pump 2.7"x2.7"x1.75" at 16W

get onto it dave, times a wasting ;)

Yes, yes. Do get on it Dave. :)

Well, get on it if it has the 100,000 hours...

"can do this with a pump 2.7"x2.7"x1.75" at 16W"

show me pls :)

Ok, Dave goes to work monday.....

Dave: Kevin can I spend 60-100K on tooling, so that the guys will be happy on pro forum?

Kevin: Dave go home and don't come to work drunk ever again!

:D

Sorry guys, you get OEM left overs. Maybe an OEM will come along and ask for this, or I can convice AVT to make it.
