Others pumps DD-CPX-Pro & AP910

[redgabber]

Hi guys

What do u think about these pumps ? :

DangerDen DD-CPX-Pro
http://www.dangerden.com/store/product.php?productid=356&cat=0&page=1#tabs
Max Height - 4 meters (13.1 ft)
Flow Max - 800 Liters/hour (211.3 gallons/hour)
Silent operation - Mag Drive Ceramic Bearing Operation

and

AlphaCool AP910
http://www.alphacool.com/shop/Pumps/AP910-1511-centrifugal-pump-12Volts--3278.html
Pump performance: max. 900 l/h
Delivery height: 2,8m
Power consumption: 10 W
Sound level: approx. 22dBA (comparable Eheim 1046)

Sounds very good.
The quiet AP910 could be an alternative to D5. (good flow, pressure is ok)
The DangerDen an alternative to Laing18w (good flow, high pressure)
Both uses ceramic rotor like Eheim (quieter)

I look silence and power. so why not...

See Martin's review of the CPX-Pro (pre-production model) all in all a good pump.

As for the other no idea oh and it should be noted that looking at just head pressure and max flow are not very good indications of the performance of a pump you need a PQ curve for that.

FWIW, I looked around for pumps and finally settled on the Laing DDC-12V from DangerDen. It's great for medium to large sized loops.

yes ..sure... specs are only paper ^^
I read the Martinsliquid test... good review for a good pump.
The video does not tell me more about silence...
I don't know if the Laing18w is quieter than the DD pro or the D5 #5

I have to make a choice for my new pump, but i m a silence addict!

Well if you read the review you might have noticed that he said the CPX-pro was the quietest pump he had ever tested.

yes..right

i note that :

The pump performs very well compared to the stock DDC 3.2. An average to low restriction system would typically see higher flow rates with the CPX-Pro, and really high restriction systems would see very slightly more performance from the DDC. The important part that catches my attention is the power consumption. At the 2 GPM mark, the DDC is consuming nearly 21 watts, where then DD CPX-Pro is only consuming about 15 watts, so the DDC at that point is consuming about 40% more power which in the end becomes added heat to the loop.

To help put performance levels into context, I've selected a range of components for several setups. Generally anything over 1 GPM is adequate flow rate and more is better although gains are generally small past 1 GPM and even smaller past 1.5 GPM.

Over 1 to +1,5 GPM, gains are small... so the higflow pumps on medium restrictive loop are useless i understand.

Well, i think i ll have a try for this pump...quiet, cheaper, spiral top is include, no extra-fittings need, sounds good ^^

[redgabber]

The only strange stuff i note is the DD-CPX-PRO feature 800 l/h
I never see a DDC 3.2 + Top running this flow rate...

[Shocker003]

if you leave in EU, why don´t you get this pump for less. The ones you intend buying ain´t close to it when it comes to power and it´s cheaper. I don´t hear it working when it´s on 12v (sitting on a form). AP1510

[redgabber]

Yes Shocker.. i m on the way to buy it.

I repeat but i never see a ddc+top running 800 l/h capabilities
I just want to know... so i ask

Nope, you won't see a DDC 3.2 or DDC 2 having 800 L/H installed in a loop, but neither will you see the CPX-Pro doing that when installed in a loop. (Reread Martin's test of the CPX-Pro again......realistic outputs from both the CPX and DDC completely depend upon the restrictions placed on the outlet of the pump.....i.e. tubing, blocks, rads, etc.)

That 800 L/H figure you see is wholly unrealistic as it represents a calculation done by the mfgr. based on a few minutes of pump output testing, output testing that was calculated when there were no flow restrictions placed on the outlet of the pump, by the way, like tubing.

do you have a review on it? i had noticed it too, but heard somewhere that the voltage controller could have some problems after some time

You woun´t regret buying this pump. For the aquatuning price it´s a steal. i bought mine €89, without shipping.

I don´t use the voltage controller, my is conected directly to my psu and it still has enough head and has never had a hic hop ever since i installed it. knock on wood. It´s the only 12v pump that is close to a Iwaki that i know atm, when the voltage controller is being used at 24v.

SANSO PDH054 is as good as an Iwaki, its very silent, and 12V :up:
thanks for the review!

EDIT: what's the noise profile compared to D5 and DCCs? anyone knows?

[Eddie3dfx]

DDC is not silent. If you want silence, get an eheim from innovatek or aqua computers. They are simply silent.

i wouldnt describe DCCs as noisy tho... just like a 1200rpm fan to me

I agree with you. But finally, i suspect the DDC 3.2 to do not beat the CPX-PRO as reviewer says, and this, with or without retrictive loop.
DDC 3.2 + Top gives 550 l/h max. Only magic spells bring the DDC to 800l/h !!! Ok there are restriction loops and variables..., but the rules are the same for both pump so... at equal pressure (4.3/4.7) i really doubt... hmmm Alien is still here mates. ;)

Note the CPX-Pro is bigger than a DDC, with stronger motor...so i don't think the manufacturer suxx with specifications.
I love the DDC, i use it, but... i enjoy to live on earth sometimes ^^

please DO NOT believe what vendor say... simply DONT. Martin's test showed its a good pump, but DCC+top is still better. i personally trust martin, he proved many times to deserve it with all his helpful reviews

[SNiiPE_DoGG]

as far as I remember from the 2 years I have spent on this forum, the alphacool is very very loud at full speed

but the alphacool is in the OP.....

I know the CPX-pro is a good pump, I had one for a bit but never used it, just sold it to another user who can make good use of it :)

I read all Martin's review and i agree...
Sometimes i m just a little confused when i see a stronger and bigger pump, built like a D5 with better pressure, be kick by a small ddc pump, ok helped with Top, but tops are not the messie.
I just ask some question to understand where i miss something.

At least, DangerDen vendors are gold farmer only and sell wrong features ?
Damned ! Be sure i will ask them about their products. I want to read more about this pump...who is right ? who is wrong... My Euros/Dollars wants to know ! ^^

The ddc-3.2 runs at higher amperes and as a result the motor has more power, fairly simple

Also the DDC impeller is optimized for pressure whereas the design of the CPX impeller lends itself to high flow but lower head

So the 4.3 pressure specifications From DangerDen suxxx !?

no, its accurate, but you have to remember that in martins review the CPX is compared to a stock ddc-3.2, with a top the 3.2 is significantly better

[OdinEidolon]

sniipe explained it all. good job mate :up:
still, i really like the cpx-1 pro. i may get one, but dcc+top isnt a lot more expensive... thinking about it
