Hopefully we can think of things your people haven't, and get them all covered, minimizing any possible failures.
I honestly never thought of it because I had thought that the pumps were all sealed bearings. But, when you mentioned ceramic bearings and water being used as a lubricant I thought about the pump manufacture that is making that set-up must have taken into consideration metal particles in the water; due to tightening of fittings, micro shavings from the block that weren't cleaned out..etc etc..and, for people that just use tap water in their system, eating up the bearings. They would have had to think of a way to get past that. One easy one would be to make the bearing harder than typical metals. That is why I thought that the ceramic bearings are probably harder than the metal. But, again, I will look into that some more.
