A positive experience with CSP Mk II pumps... hmm let's see... no, can't think of it. I had two of those (actually still have 'em only sitting in a box) running in 2 separate loops and they were humming happily for a while (about a month or so) and than started to get very, very noisy. It's gotten to the point where I simply took 'em out and plumbed in my old L35 to carry me over 'til my DDC's arrived. I never experienced any leaks or had corrosion issues. I checked the insides when I took the pumps out and they appeared to be clean. Yet they sounded like tey were just about to die. Didn't want to wait and see if that will happen and how soon.
Now I'm not an engineer or have any technical background, so with that being said, to the best of my understanding, the issue about running these pumps in series relates to the shaft seal that may cause a leak due to increased pressure. So it's a definite no-no.
