We have the same pump/ generator and have had similar woes when using those blue "run dry" impellers. It would spin the hub out of them because they are plastic. the hubs need to be brass (bronze?) . We also had a problem where I tried to use gasket goop instead of a paper gasket and the impeller bound on the housing without that little bit of extra space. Could this be the phenomenon that is causing your impellers to go?
