Saw this on the alphacool site.
Rather curious as to what it is exactly? (other than noisy)
If anyone has any experience of one, or any idea how it works...?

Hello Rosco! Thanks for clarifying (Diaphragm pump). Couldn't find anything on Google, was also wondering what the original app. may have been!? And if that is a bona fide 50khr MTBF ...
(could use something like that for my "geothermal" AC - need at least 1bar, and 3lpm is just about enough for a 22°c setpoint )

Hehe you are lucky, I search again and found it . It's a 50 Hz piston pump in fact, not a diaphragm...

Roscal
when you search, do you you do so separately in each language ?

ok, I had kind of assumed that might be the case
but then you search in French, German ?
Spanish and Italian also ?
at what point are the returns not worthwhile ?
(I guess that would depend on the topic)

I did attempt to do a search in Russian (using google), but it was difficult, much info there not too apparent to us

EDIT: nice article BTW, on quiet psus

English and french are sufficient for me (spanish sometimes). Generally, I always find what I need so no problem.
Search in Russian should be about very specific/special info...

Thank you very much: that info was exactly what I was looking for (and didn't find, lol)
Pity the flow drops off like that, was expecting it to be constant

Yep it's not a true volumetric pump (too weak) with a constant flowrate in any situations (according to its mechanical specs).

I have no experience with the pump. The various models are all just the same pump, but being run at different voltages. The AP1500 is just an over-volted (17V) version of the 12v AP900, and from what little I know about it, is actually fairly noisy at 17v, but that's just second-hand knowledge.

If we assume 3m of peak head, peak flow of 25LPM and 17W of power consumption, this pretty much places the pump on a near equal performance footing with the muffled Laing D4's.
Thanx so much for sharing your knowledge with a water noob like me I'm hardly trying to setup my first WC setup...

Great information, what makes it even better is that I bought the AquaXtreme 50Z-DC12 before reading it and it confirms my choice.

Thanks

This has been a slightly exhausting thread to read, mostly because a lot of the technical stuff goes over my head. I'd like to ask one question . Is it ok to put 13.8 volts through a D4 or is this a bad idea

Fine. That pump can tolerate more voltage, I'd say up to 16v or so, but as always, YMMV when overvolting/overclocking.

If I remember right, the original atleast was good up to 20~24v because of its original use in solar.

jeez, read the pump specs, 24V is a different motor

Ok Bill, I'll ask you, will it be a problem if I shoot 13.8 volts through a D4/650. If it's not a problem will it help performance?

more volts = more power/rpm = more noise = shorter life (taken to extremes)
13.8V is fine, not too much ripple eh ?

I have an AIM 6 amp precision regulated low ripple power supply laying around. Thought I'd put it to good use if it'd be ok. Volt meter says it's putting out 13.57v

sorry for digging up a thread, but Cathar, i know you have an iwaki RD-30 now, how much heat (w) does that dump into the loop?

It dumps around 80% of its power draw into the loop as heat. At 18v in achieves something like 7.5mH2O of peak pressure, around 20LPM of peak flow, and draws around 30W of power when installed in a system. Those figures are from memory. Am not at my desk in Australia where I wrote them all down.

This is confusing me a little bit.
At 60Hz the head and flow is larger, yet according to Iwaki's PDF the amount of heat dumped into the water stays the same.
So the 60Hz version should definately perform better, right? :shrug:

I'll be testing a few pumps myself soon, and I don't want to make mistakes.


EDIT:
Unless of course by output they mean the amount of heat transferred to the air?
If that is the case then the amount of heat dumped into a loop by the 30RZ is very low; that's very unlikely.
I guess their numbers are just way off...

afaik motor input is the power draw (higher at 60hz due to the higher motor speed) - if you look back on page 1 cathar has a 30RZ at 50hz dumping 50W into the loop (this was obtained from experiment iirc as that's the pump cathar used to have, on his 50hz aussie mains.)

so assuming the same % of input transmitted to the water that'd give about 64W at 60hz...

not sure what output is in the PDF?
