Being picky here, but  .  .

Cavitating is what happens when a bearing wears out and a spindle is no
longer rotating around a single axis.

In other words the pump's spindle is kind of rumbling  around a wallered out
hole instead of simply spinning.  Really has nothing to do with pumping air;
it's just not pumping much of anything.

My apologies for the poor description.
