Its like watching 'The Wall', but instead of hammers, its skimmers...

Seems like the actually borrowed some from the ATI's, but I ATI took their design from Meerwasser-technik (designed for Fauna-Marin), and those guys are friends of Klaus. The design does enable the bubble plate to be lower in the skimmer... so no complaints there. Looks like a winner to me... larger bubble plate and all... I wonder if the bubble plate contents will be 'spun' or just direct inject... I would assume 'spun' or the bubbles might build up under the flat parts of the plate.

Drooooool.

Just under 20" tall (50cm)

10 year warranty

Not intended to replace the existing UC deluxe or mini lines, but a new line intended for small spaces.

Nice bubble plate, nice neck diameter, good looking, unique impeller disign.....does look like an ati imo. Would like to see one up and running and what it is pulling. And would like to see measurements as well. Is it 20" tall and 10" diameter or what.
 
There is a 200, 250, and 300 model (G-wiz... aimed at ATI maybe?) The model number of course being the cylinder diameter. The air output of the 250 (the one shown) is going to be 2000lph via a Red Dragon 'loopwheel' which only uses about 35 watts.

Thats it... the new BK 'supermarine'.
 
What gets me is that the real design advantage over the other brand is that the bubble plate is much larger, so it actually acts as a turbulence diffuser... unlike an ATI which shoves all 2000lph of air and 3000lph of water up a 7" diameter tube. Thats great and all, but then there is that cone which ends up being a nozzle anyways (shoving it all back together). It seems like the two cancel each other out. There is just no way to make a bubble plate better other than to make it larger in diameter. Either that, or make it a 'ball' or 'bubble sphere'. I have one that allows me to run 3400lph of air in a 12" diameter body with ease (and little turbulence). The 6" sphere has 4x the surface area of a 6" plate, so its much more diffused, but also, the downward holes allow alot of the water turbulence to escape out the bottom leaving the top very calm. It means I can have a narrower body, although taller as well, with a bubble diffuser. Now I can have a bubble diffuser in a regular ole' tall and thin skimmer, rather than a short and fat ATI/BK style 'fatboy'. The cool part also is that the base plate is removable to clean under the bubble plate.

Thats it I'm getting one. They just look so cool!!. LOL.

:lol: I want one now! I like the design of those skimmers.
When is this spending spree gonna end?:mixed:
 
Hahn, is that the titanium threadwheel, or another alloy? I can't read german so I have trouble keeping up with the forums that Klaus is usually on. :)
 
Also, whenever I see RD pumps it just looks like there is a lot of extra room inside of the volutes. what is their reasopning for that? My thinking is make your meshwheel as big as you can with the pump still starting. seems like they could use an even smaller pump and get the same results if they'd just use all that extra space in there.

Another eye candy bud! Shall we?:lol:

Hehe! I'm still playing catch up for my last few purchases! :) I wonder what the footprint is for the smaller 100g'ish models... There's always Christmas I guess! :D

Okay, skimmer pump 101:

Its not the size of the impeller so much as the size of the volute/impeller well. Look at other RD pumps, and even Lagunas which they are based on. The impeller is rather small... as long as the impeller can spin the contents of the pump at a certain speed, the centrifugal force made by the impeller doesnt relate to what size it is. The best needlewheels are made with low-pressure, high flow pumps... or Pond pumps. Larger impellers have more to do with higher pressure pumps or 'high head' applications where you dont want the back pressure to be able to 'slip around' the impeller. Then you would have a larger impeller as well as smaller output. But for needlewheels/meshwheels, or the new Titanium Loopwheel that Klaus is sporting here, the diameter of the impeller isnt so important as say... the speed, since its a lower pressure, high flow application. You only need a larger diameter needlewheel impeller when you are talking about taller skimmers. The oceanrunner needlewheels are a good example of this... they can still pump about 500-600lph of air on a 6' tall skimmer body... something a RD would choke on.

At that, yes, the Red Dragon might use a larger diameter volute compared to the Lagunas... MIGHT. The volute is what determines the air capacity of the pump more than the impeller size. An impeller spinning around in a small volute with air doesnt do much. By having the impeller too large and the pump volute too small, you can actually kill performance by taking up volute volume that air could otherwise be. See, the Red Dragons were made when the Lagunas they were based on were smaller volute designs with a central outlet. So Klaus made the RDs with a tangential (unidirectional impeller rotation) output and a larger volute, AND, the most important thing, he swapped the stock Laguna impeller which contains brass for something else. The latest generation Lagunas include these things though. The volutes are larger, the outlets are tangential, and the impellers no longer contain brass (stainless steel though).

So, now Klaus has a new Silver Dragon/Red Dragon 2 on the way. The 5000+rpm speed that you can get with a DC motor just kills what a regular AC powered pump can do. It can run faster (and is adjustable through the voltage), its unidirectional, and the torque is much higher so you dont have the startup issues like with AC needlewheels when the impeller gets too large. The torque applied to the impeller is also much smoother than AC... with AC you get 'gaps' in the torque as the impeller rotates due to the frequency determining the speed/alternation of current in the stators. With needlewheels this can be very bad because your typical needlewheel runs very out of phase with the current. This causes heat due to the real power that the pump consumes which is often much higher than the RMS wattage... this means poor power factor and pump efficiency. This is why many needlewheels run hot or even burn out faster compared to their regular water-moving versions. This is also the cause for resonating vibration from the pump.

A DC pump removes power factor problems as well as many other problems. They are often much more efficient for other reasons as well. You can have a 45wattDC pump do what an 80 watt AC pump might do otherwise.
 
Is it just me or does that look like an old idea of mine used in the bottom of that bubble plate chamber? Anyone else see that hole in the bottom... I wonder if thats plugged, or if thats a pressure bleed hole to let the bubble plate be even less turbulent... hmmm...
 
Am I to assume correctly that these are NOT Askoll pumps? These don't look like the Laguna's at all, and they are DC. Are there DC pond pumps in the US>
 
Hahnmeister, I would think that is the input for the pump. I may not be looking at the same thing though.

Also Klause answered to a post on zeo stating he has been working w/ a conical design since 2004 and a speed controlled pump since 2005.

The metalic meshwheel is a patent of RE and not a invention from other company. The material he uses he posts as being Hastelloy C22.

I'd attach a link but I don't know if they allow that here.

IMO after looking at the pics of Klauses' factory I don't think he is in the business of copying anyones designs. He is setting the bar for others to reach for.

JMHO,

Chad

well he did a fine job of immitating ati/others here, they had the alloy mesh wheel idea first, and controllable skimmer pump idea first as well, and hmmm, go figure, the ati bm300 has a cone as well.
im not saying it isnt a great, awesome looking skimmer, and incredible build quality, im just saying that everybody in this industry borrows good ideas from other companies/people, as klaus has obviously done here.
now, lets see if he borrowed ATI's best idea of all, an affordable price!!

i definately DO want one though...:)

Man everyone copies your ideas... It's just not right
