You sure those were made by Eden?? The compact+ eheim rebrands were absolutely, but the current CompactON rebrand of the old marinelands seem like askoll motors to me. I'd favor them slightly over the Eden built punps personally. The cord insertion and bearing designs on the old marineland 5000 pump were purely askoll design to my eye when I've worked on them.
As an aside have you seen the larger Rossmont AC controllable pump model ? Looks identical to the marineland 5000 or the compactON 5000. I wonder if rossmont is having that motor block OEM built by askoll too.
