Topic: Re: What’s the right piping design?

There is obviously a lot more to this problem than you have chosen to tell me.
Without knowing any more, I must ask why you reduced the size of the pipelines? This only increases the friction losses in the lines assuming you are pumping at the same flow rate. This in turn would increase the KW draw from the motor which, in turn, would cause it to trip out.
I don't understand your comment: "the pump damaged the stator.”
