These are positive displacement compact pumps, suitable for very low fluid temperatures up to -45C (perfect for liquid chillers ). Also have very high pressure and good flow, virtually not dependent on the flow resistance.
The only thing i cant find is their power consumption. If its high, than they are useless.
Wow that is extremely high pressure...my guess is they're power hogs because of that

You could email and find out.
Already found. The power consumption is probably acceptable.
As i am thinking about building low-temperature phase chiller, i am looking for good pump capable to work at -40C -50C or even lower. That is the first series of compact pumps i have found rated for -46C.
I wonder what the internal components are made out of. Hopefully you don't have to worry about mixed metals.
SERIES GN 22.7 L/min
(6 gpm) 42 L/min
(11.1 gpm) 6.9 bar
(100 psi) 103 bar
(1500 psi) 24.5 ml/rev
ROFL..... that looks really strong.. 100psi!?!?!??!

Looks okey, i dont see anything that would cause a problem. However im seeing Ti, so im guessing this is uber expensive. :X
ummm im also starting to think this thing might dump a crap load of heat into your water as well. :T

If that Ti is exposed to flow then you might want to check the potential for galvanic response. I know that titanium and aluminum do not get along at all (much worse than copper -> aluminum if I'm not mistaken).
I don't believe that Ti -> Cu presents a significant potential for galvanic reaction, though it would be wise to investigate.
Edit: Just noticed NaeKuh's post that lists the Ti as a wetted material. So yea, check out the reactions.

Look at the tyranny of party--at what is called party allegiance, party loyalty--a snare invented by designing men for selfish purposes--and which turns voters into chattles, slaves, rabbits, and all the while their masters, and they themselves are shouting rubbish about liberty, independence, freedom of opinion, freedom of speech, honestly unconscious of the fantastic contradiction; and forgetting or ignoring that their fathers and the churches shouted the same blasphemies a generation earlier when they were closing their doors against the hunted slave, beating his handful of humane defenders with Bible texts and billies, and pocketing the insults and licking the shoes of his Southern master.

Exactly what I said. 100psi is INSANE. 100psi translates to several hundred feet of head.

looks really interesting! Once you find something out report back. It might be a good alternative to the DDC if the reliability is better and the price and performance is right.

I have a feeling these are very very expensive.

So do I, unfortunately. They look like they wouldn't be cheap. I'm guessing mid-$100's.

Tooo bad for you guys you're going to have to use high pressure hose to contain this kind of pump... Tygon or PVC will not work.
I believe the tygon 3603 is rated for 38 psi and the highest psi tygon is at most 50-ish.
it was a cool idea, though, not so cool under pressure
it could work if you used 3/4 tubing lol to reduce pressure
Those 100psi is a maximum head pressure the pump (some versions, not all of them) can sustain. If the flow resistance is lower, the pressure will be lower.
The pressure can be as low as required. 10psi or 20psi, and still at several gpm.
I think that's burst pressure for the Tygon, which it wouldn't reach unless you were using really tight compression-style fittings. Tygon is so soft, it leaks like crazy at moderate pressure with any kind of hose clamp/barb setup (especially with worm-drive clamps). I hate Tygon

PD pumps are insane, they push the same GPH no matter the restriction... the key is not having too much pressure as you will bust your rads in quick order.

Why are people SO WORRIED ABOUT THIS?????
I have said it many times.... please either screw on or solder a piece of zinc on ANY OF THE METAL SURFACES... this WILL avoid the corrosion of the alu and copper. The ZINC WILL corrode, but not your trusted cooling parts.
