Calcium Reactor and Kalk Reactor

[stephane]

on both end of the ceramic shaft there 2 ruber bushing when I dont clean, the impeller magnet jam on the ceramic shaft so the shaft spin with the bushing burning the plastic hole were those bushing are in

then It is impossible to repaire other than glue the buscing on the pump but if you dont clean the shaft will turn inside the bushing burning them and the pump is scrap

maybe the smaller model dont have this problem and when the impeller
jam on the shaft they simply dont restart but the 18 is very powerfull IMO two much for plastick
