There's no version 2 in fact, they only added external fix on the body as a little improvement.
I don't know what the matter with graph but their 570L/h are impossible to achieve @12V with my test, for sure ! I mailed Ralf from Laing to know exactly the conditions of their test because, as usual, a lot of data are missing (voltage?).
Here's his first mail to my question about these strange 570 L/h today :

Hi David,
About the flowrate:
Before we used the pump curve for the requirements of Delphi (we stopped measuring at the 270 l/h), now we measured to the maximum characteristics, that's what we'll use for the end customer market.

Is maximum characteristics refer to 13.2 V, I don't know it's not clear...
Bill I'm waiting your test, it take a couple of minutes to confirm or not.
