Experience with Royal-Exclusiv Red-Dragon Pumps

[gothunder3022]

Is anyone out there using a Royal-Exclusiv Red-Dragon Pump? Are they as quiet as they advertise? I'd appreciate any feedback.

I have no direct experience with them but have seen some threads about some possible quality control issies on some models.

But as with everything on the internet this could just be overexposed making it appear to be more of a problem than it really is.

I personally have never head anything but great things about them. The only bad thing I have heard of was the price.....

Yeah, the price will definitely take your breath away. And there doesn't seem to be a used market for them.

I've done some additional research (including a call to Proline Aquatics - the North American distributor for the Red Dragon pumps).

The pumps referred to in the link that braddo kindly sent, are a newer model (Red Dragon II) that have been voluntarily recalled due to a variety of mechanical and electrical problems...sounds like the problems don't appear until after 12-18 months of SW use. These are a DC controllable version.

I'm mainly interested in the AC RD models like the ones MarineDepot sells. The guy at PA swears they are dead silent...which I need if the tank is going to be in the house.

If I am not mistaking the RD pumps are the same as the askoll if not just a step or 2 up from the Askoll. If so the Askoll is dead silent as I have one running on my skimmer.

That's good to hear! A little searching showed the RD pumps actually use the Askoll motor block...thanks!

No problem glad I helped.

I think your good if the RD pump has a gen 2 impeller!

Do you know the best way to identify these? I've found write-up's that mention the "addition of an anti-lime calcium bypass to the Askoll OEM motor block", and that the RD10 and RD12 models have a titanium shaft upgrade. But nothing on the smaller models. Is the red bypass tube the best way to tell? Thanks!

I could order a pump for you and call them to comfirm that is has a good impeller.

Let me know.
