If you look at the curves for a second, it looks like you can substitute pretty much any centrifugal pump curve for the Iwakis... you're going to have different flow results, but the conclusions should be the same. I'd guess that the Eheim results are similar in character to the Iwaki 20R results... i.e. a less pronounced advantage to having the blocks in series, but an advantage none the less.
