I guess you could argue that my pump didn't fail, my impeller did. Lol.

Usually bearing fails then the shaft gets wobbly so that the impeller interferes to aluminum casing to destruct itself. And the bearing could fail on its own or due to leaky mechanical seal that allows coolant reaching to the bearing and washing out grease.
With your failed pump, was it just the impeller disintegrated from tight and straight bearing shaft?
