I have an Iwaki MD-15R given a vibrating sound inside, almost like rattling. I'm running it with two MCW-5000A, one MCW-50 and a Thermochill 120.3 all in series and the pump is too hot to touch.

I know the Iwaki pump bodies run hot, and I have read Cathar's advice to others regarding Iwaki pumps needing some sort of restriction to minimise cavitation. Would the stuff in the loop be enough restriction? Or am I expecting too much from my pump?
