Dabs, brill pumps had 1 failure in umpteen years. Had more failures on Grundfos than Dab. But I'll still use both pumps. Dab I think has slightly more RPM than the Grundfos 15/50.
DAB is apparently owned by Grunfoss.
The parts are different though and the finish looks a little rough.
Grunfoss have hard ceramic bearings but I seem to find a lot failed due to burnt out motor windings.
I have only come across DAB pumps during the last three years and have hardly ever seen any installed, perhaps because they are so reliable.
