mini red dragon

[slowsoaks]

Could you tell me what the max head pressure for these pumps are? Are they similiar to the regular red dragons? I was interested in using one in a set-up that has the sump in the basement.Thanks Mike

Hopefully we can have you an answer shortly. We have contacted the Mfg. in Germany for more data on the mini Red Dragon pumps.

Hi slowsoaks

The minired dragons lokked a little bit different then the Red Dragon pumps but the motor unit is the same only little bit smaller.

The mass of the pump

150 mm long x 91 mm x 200 mm highly

Suction face 32 mm 32 a sleeve or 32 it screw connection can
are attached
Print page 25 mm 25 it a sleeve or 25 screw connection can
are glued on.


* Magnet centrifugal pump

* no metal parts, thereby absolutely sea-water resistantly

* no heating up of the aquarium water

* low current consumption during high mechanical handling capacity

* almost noiseless enterprise

* Enterprise also under water possible

* intervalable

Mini - red Dragon of 5000 litres of 3.5 meters max. hoisting depth of 60 Watts

The smaller ones has max around 2,2 m

"* no heating up of the aquarium water"

From the laws of thermaldynamics, one 35 watt pump will heat up the water just as much as any other 35 watt pump though. The one thing Ill give the Red Dragons is that with the motor-block's built in chip, the power factor correction it does keeps the pump's REAL POWER very close to that of the RMS wattage, so the VA (what really determines the power a pump uses, as RMS is just what matters for your electric bill) is kept much lower, and therefore the heat as well. A 35 watt Red Dragon may only have a real wattage/power rating of 40-45 watts, where others, like say, the Sicce PSK 2500, a 23-25 watt pump, is really using about 70-75 watts (a very hot running pump indeed).

This makes these pumps very nice when it comes to cleaning: a pump that runs hotter will build up calcium inside much faster.

I've heard alot of talk about problems with these pumps and poor customer service, has anyone else heard of this?

I think you have heard wrong and I doubt the manufacturer appreciates you posting false rumors or hearsay in the forum. I'm asking RC to remove both of these posts.

We sell a lot of RD pumps and on very rare occasions we have to service one of these pumps.

I dont think you are starting rumors Radar1. In the past, it seems people who try to get service from Royal/Klaus directly have had some problems, mostly due to translation gaps. I wouldnt blame or even think Aquarium Specialty would be aware of this, and Im sure if you deal with them the results will be fine. But one look here at RE's zeo forum:
http://www.zeovit.com/forums/forumdisplay.php?f=95

or the RE forum at meerwasserforum.com (German):
http://www.meerwasserforum.com/board.php?boardid=47

And you get a pretty good idea. Also keep in mind that these pumps are the vast minority. You dont see people who are just happy posting that their pumps are fine in those forums because, well, there is nothing to report... so a little bad press really goes a long way. But what you can see from above is that Klaus is much more available if speaking German, but unless you speak German, you should stick to the dealer for product support. This is why RE switched to Proline and the new ideal is to deal with the vendor/PRoline rather than Royal Exclusiv directly: to improve customer service.

[AquariumSpecialty]

Well stated hahnmeister. For those that don't know, Proline is actually the distributor and they do not sell to the public but we do.

I probably should have elaborated a little better in my previous post. It's been a rather stressful day and as you can see I'm still working and it's 10:01 EST...actually that is typical for me :)

[Radar1]

Sorry to offend. I wasn't trying to throw down but rather ask as a concerned potential customer considering a RD pump for my new elos tank.
I have been visiting aquarium specialty for the past few months collecting a wish list for my new tank, I sure hope that you wont respond in such a defensive manner to any of my other questions or concerns should I choose to do business with you in the future!

I was a little on edge when I posted this. Please accept my apologies.
