Alex sorry to piss on your fire but i just checked and my DDC is a 3.3 pcb!!

I've sent a indepth e-mail to Robin @ Laing with an excel spread sheet trying to work out what the hell is going on with all the pump names and stuff.

Why do the europeans have to have a differnt name to the US....

I should get soemthign back tomorrow..i hope!

Have attched the doc here. I got that off Robin months ago but i think something is very messy somewhere now

Yes, my 18W blue impellered pump also has a v3.3 sticker on the PCB... However, I'm referencing pump model names. The thing that your chart isn't taking into account is that the DDC-1, DDC-2, and DDC-3 series don't share the same motor. This is why there's a large performance difference between the 18W DDC-2 and the 18W DDC-3.2

In short, here's my understanding of what's going on (keep in mind, I'm referencing model numbers... not PR names):

10W DDC-1 & 18W DDC-2, both were available in the US and Europe up until Laing replaced the DDC-1 (black impeller) & DDC-2 (red impeller) with the DDC-3 series (resigned motor and blue impeller). This changeover happened first in Europe because, well, that's where Laing is based.

The DDC-1 and DDC-2 are still available in the US because Laing's US division still has about a 6-month supply left in inventory. Laing's US division seemed to have been caught off guard by the change, amusingly enough. Now they're being pressured to cook up a version of the DDC-3 that has performance equivalent to that of the DDC-2 before they run out.
