Danger Den CPX-PRO Pump previewed..

[Martinm210]

As always, Nice review Martin!!

Question, in the last graph (right above this post), does the MC-TDX had a nozzel in it? or is it just a stock MC-TDX?

How well do you think this pump would do with an MCR320, Fuzion w/Quad Nozzel and an MCW30 NB block?

My system spec's in sig.

That's the MC-TDX, it does not have a nozzle, although I keep hoping they may come out with a kit for them. It's a low restriction block, pretty similar, just a touch lower pressure drop than a Fuzion without washer/without nozzle.

simple things works best, no balancing impellers like DDC rotors

as always Martin you did it again love the gate valve on work bench

Thanks to you for the sound level meter..

Danny is certainly not going to be happy that Danger Den beat him to the punch... he has been telling me about this thing for quite a while now.

Anyway, the performance curve looks promising... If the noise level during operation is anywhere near the dB-1/CPX-1, then I'd think that we have a real winner here

Not sure when these will make it retail, but they are coming. The sound level is pretty good I think. I've never tested the CPX-1, missed my chance when Naekuh let me borrow his and I ran out of time. I only measure 3-4 db over my 47db ambient and that was only about 6" away, so pretty quiet overall.

That pump is awesome!

Very nice review!

When get your D5 tested..

Could you make a graph where you compere flow estimation between a setup like this. DDC w/o top, D5 and CPX-RPO and then maybe a performance vs price compare something

Hope you get it

Sure, but I need to finish my DDC 3.1 testing first.

so this thing is pretty much equivalent to a ddc with a top except more quiet?

Not quite, it similar to a DDC 3.2 without top. Once you put a top on a DDC 3.2, the DDC 3.2 with top is going to be more powerful. But the D5 and DDC 3.2 with top are really more powerfull than you need on alot of systems, I've heard a few occasions where folks get better performance with a D5 on lower settings. This isn't normal, but it happens when the higher pump heat dump at higher settings causes more harm than the added flow rate thermal improvements. Heat dump is the tricky factor and plays a huge role in pump selection. This one's similar to a stock DDC 3.2, which would be more powerful than a DDC 3.1 and it has high efficiency.
