This test is brought to you by NaeKuh from XS, thanks for loaning me the beast for some quick tests..

Expect to see a flow meter pegged and my new 20.00 psi manometer to be challenged...

Before I do...what voltage runs would you guys like to see? I can see it will already run at 12V just fine.

I'm thinking:

12V, 15V, 18V, 21V, and 24V?

Anything else?

Test Bench:


A quick maximum head test...14.66PSI anyone?..


Running to get the worm drive clamps before it's shower time...

Alright I've got the preliminary results posted, still working on getting a video in there:

Here is the 24V curve, I have all the others as well on the site:

Excited and Can't Wait! Those voltages to me seem fine!

Really interested in the 18v..... seems to be the popular one that I hear everyone recommend!

Thanks Martin and NaeKuh

That has mine beat by 0.44psi, it ain't fair......What is the heat dump on those at 18vdc? Mine is around 31W....

Not bad at 18V, but climbs alot after that.

18.0V at 1.5GPM is 29 watts..it's a really nice pump.

Just finished testing, and getting my results put together.

WOW !

Some quick math comes out with 33.8646 feet of head !

Impressive !

Yeah 18vdc is supposed to be the heat dump sweet spot for them...There very nice, Petra and Jab-Tech were both out of stock when I bought this 20RZ, I should of waited to get one since i ended up not using if for 2 months anyway....Oh well if I ever get a chiller made this AC Iwaki should be very durable and its close to the RD 30 anyway....

Did it collapse that small tubing on the suction side yet? I have to use some thick wall tubing with the TEC or it will...I need to hard plumb it with PVC next time I break it down, it looks like a zip-tie party right now...

Got some results up...was a long day yesterday getting these done, still working on the video for noise checks.

Thank Martin...Power consumption and heat dump sure jumps at 21vdc....Are you going to try it with a block and rad on it?

Yeah, I can see why 18v was recommended before, it's definately tuned for higher flow rates when you get above that and you start falling off the curve and heat increases.

No, I only have the pump for a short period, planning to ship it back tomorrow. He's building a new system with it, so I just managed to borrow it in between builds.
