The first thing you ought to check, is your pump inlet connection: it's very likely that it is sucking air into your loop, at that point.

Cavitation would be the second thing to check, but not easy to do: try running the pump in a simpler loop, just as a test (i.e. pump and res only). Then you'll know.
