Hahn, so I'm assuming that pumps such as the Tunzes, Vortechs, and Resun Wavers are all low-voltage AC pumps with at least a two-pole design. Is it impossible to make a true DC submersible pump?

Well, ATB was before them even as well. I think the whole idea was that the BK one is a contoured funnel, not just flat sided like the KZ, ATB, etc. If there is any advantage to this, I dont know, but I would suspect there is since Aqualine patented it for their collection cups (and it works rather well too I might add).
As for 50hz/60hz pumps... it depends.
The core of the pump, as in the body, might just have a changed plug, but the other problem is voltage. A 220v pump can easily run on 110v... the oversized stators/windings on a 220v pump can easily work on 110v (but you wouldnt see any US pumps being sold in the EU w/o massive reworking for 110v >> 220v). The downside is that the torque is lower, so startup problems can happen. So the impeller is often swapped out for something slightly smaller.
You will note that while the US eheim hobby pumps do run faster, they have less torque... so you need to run a different impeller than EU ones. These impellers are smaller, so the handling characteristics of the pumps change.
They gain the higher speed from the frequency, so under low pressure/back-pressure applications, you may see an actual increase in throughput. Usually, converting a pump from EU to US by just modifying the impeller like this changes the pump to a slightly higher flow, lower pressure pump. The smaller impeller blades mean that back-pressure takes a larger chunk out of the flow than the EU version as soon as you start to add back pressure. All those claims of the US eheims being such better performers than their ratings are half-true... they CAN be better performers, and how most people test them, they are (because its just a small head-pressure or something) worse performers when you start adding pressure.

DCs are not impossible at all.

Thanks for clarifying Hans. For the record though - I've tested Eheims on an AP702, H&S 1x1260, 2x1260, 3x1260 and the range has been from 850-1,000. All of which are higher than any European draw. There was a direct correlation with the height of the skimmer. Maybe when you get to say an AP1003 you might see an Eheim draw decrease down into the 700's - but I still think thats higher than what I saw on European websites. But I learned all that info many, many beers ago ....
Edward - those new ones are sexy! I wish they'd just slap on a RD and send me one. :lol: And I don't think either is the "main" distributor. PA is one of a couple companies that now sells them. I believe Aquarium Specialty is the other. Not sure of the other vendors, but I sure hope Finsreef is still in the game. I think the old bad rep of R-E will soon be gone (service, wait, parts, etc).

I kind of think PA is in and CO is out. Just a feeling. From what I read over in Zeovit, I don't think CO wanted to carry the Mini-BKs, so maybe they got outst?
Looking over at the PA sponsored forum, they are behaving like they are the exclusive master importer now. Just a feeling by the way the thread reads on the new reduce pricing on the BK skimmers.

The Red Dragon2 is real a three-pole design Brushless DC/AC submersible Pump and running on all Frequenzes around of the world. 220 Volt- 50 Hz... 220 Volt - 60 hz or 110 Volt - 60 Hz: ... No problem for DC-Pumps with inverter... The intelligence electronic is more expensive as the complete motorblock. You plug in the RD´2 and the electronic is found your electricity and give the right command on the motorblock... are you programmable 3500 rpm, the Pump is allways runing with this speed...
The Red Dragon2 have softstart, Speedpoti and by using a Ocean-Simulator you can running 8 x RD2 to one Oceansimulator and all Pumps are programmable for softstart, highspeed, time for high-speed running, night-energysave programm and more toys for Users...
you can see the new Pump on MACNA in Action.... and we show you the first highspeed DC-Pump with speedcontrollable 5000 rpm on a 400 internal BK-Skimmer....@Standart RD-Pumps...
dont have restarting problems. The RD-Pumps are free from restarting problems. Only the first 50 RD-Pumps are we sells 2005 in USA have a restart-problem. So we ordert a 110 Volt/60 Hz inverter, where make identity US-voltage and so we testing all Pumps with US-voltage...So we changed the impeller design less 2 mm and the Pumps running perfect on 110 Volt. The Motorblocks for RD-Pumps are original for 110 Volt/60 Hz include US-plug.
So we redesigned this month all RD-Pumps for US-market and the new RD-line have all US-Unions for inch-pipes....
best regards... klaus
PS.. the RD 2 are for big tanks for more as 500 gallons...
Well
I guess the cat is out of the bag ,We were going to make an announcement @ MACNA ,but since I got 15 emails over the weekend asking the same questions ,we thought it is necessary to let everyone know who is supporting the Royal-Exclusive line of Products here in US.
So Here it goes:
Proline Aquatics is proud to announce to be the North American Dealer for all Royal-Exclusive Products.
of course we have made announcement to most dealers ,however due to the anticipated high demand specially because of the Mini BK series Release & major price reductions all across the board,we decided to allocate most of our first shipment
Premium Aquatics & Aquariumspecialty ,to be able to reach a wider audience despite of their geographical location.
Our rather large first shipment should hit the port of Seattle soon & We have included a large supply of parts in the order to make sure we can answer any demand for parts or Warranty Issues here @ home.
We are a wholesale company & do not sell to public ,all claims will be dealt with directly through the vendor you purchased the product from ,however @ any given point you are more than welcome to contact us directly if need be.
support@prolineaquatics.com or
Toll Free:1-877-682-3474
We will be displaying some major Innovations from several German companies @ MACNA this year.
of course the New RDII & the ocean simulator is on the top of our list ,but many many more as well ,Please do visit us @ MACNA, Although we do not do any retail sales we always appreciate your Comments ,suggestion & also like to know what challenges you are facing with your projects & in what we we can be help.For all you guys that we had the pleasure of meeting @ MACNA 2006 in Houston ,please do pay us a visit again this year .It will be worth it I promise.
Many Prizes & Promo Items to give away this year,you never know Klaus & I might have a few brewskies too many one night & give away a free skimmer the day after.
Klaus Don't worry I am not drinking right now ,It 's just a thought.
Looking forward to see you all there ,do not hesitate to call ,Email or PM us if you have any questions in regards to the products we carry.
Sincerely

Proline, will you be the only distro or will we be able to order from Gary at Captive Oceans as well?

Excellent, thanks - I will call Jesse. I have always thought PA and Aquarium Specialty are two of the very best large online vendors in the county. It looks like RE is in very capable hands! I can't wait to see those Supermarines. They should just be rigged with RD pumps to get them to market quicker.

any rough estimates on the supermarines in terms of aquarium size?....prices wouldnt hurt either

I recently sold my BK 250 internal for a KZ small version.. It 1/3 the size and outskims the BK hands down.. I bough tht KZ skimmer put $800 in my pocket and have a much better performing skimmer.. For the money guys you can have a better skimmer and cash in your pocket. Don't beleive the HYPE...
Happy Reefing.......

the same can be said for the kz, modified becket (thread started here on RC) with a cone reaction tube.
honestly i am most intrigued by the supermarines due to looks. extremely well crafted and as sexy as skimmers come. orange plastic would never make it near my tank jk.

I got mine from Thomas Pohl direct from Germany but www.fragfarmer.com has 1 or 2 left.

Or just buy a beckett and put another $600 back into your pocket instead of the KZ. Come on... do you really think that drilling a few extra holes in the thing and using a 'funnel' shaped body makes it that much different than a MRC, Barr, PM, Trigger, Aerofoamer, etc? Its a beckett, which means back-pressure on the pumps, and less air intake. The KZ's get away by having the skimmer in such shallow water, and having such narrow body's... so it looks like alot of bubbles... and there better be with such a a high wattage pump. But make no mistake, plug in a watt meter to that thing and see the electricity add up. As of yet, no injection system is going to beat an asperating pump for efficiency... except for a linear air pump fed skimmer.
