Okay, 4.5 months later...
My second Johnson pump arrived well (differred from the first due to a shipping error from Surplus Center).
Drawback is that I payed 215US$ in total for both pumps...
For that price I could have bought an Iwaki...
, or two mag drive Johnson CM30-P7 pumps locally...
Everything would have been fine if there wasn't the possible leaking issue with the CO30, I really can't trust those pumps anymore.
However, I tested them in my kitchen sink and I am really pleased about their performance (flow, head, power consumption) compared to my Eheim 1250, although they are more noisier.
I also have to say I have a quite restrictive WC setup (quite a lot of 15mm 90° copper turns) and with the 1250 I obtain a flow of 4.40 liter/min.
My Cascade WB is waiting since a month to be mounted, but I'm afraid that the final flow will fall to a couple of liters/minute.
That's why I was looking for an affordable pump with more pressure and head. (the new Swiftech MCP-600 is not really a contender for the Eheim 1250)
I have to admit that a little pump leak would not compromise any of the components in my setup due to the position and location of the pump (vertically between mobo and HDD cage in a LiLi PC-70 , with the pump inlet downwards), and I can always put a little recipient under the pump to catch the few drops that could possibly leak).
So, back to square one...
PS: Would it be usefull to start a poll about the number of leaking CO30's, and after how much time?
