Heading problem?
The pump suctioning is greater than the actual feedback of the entire
system?
Thus it makes vapor or gas bubbles... etc?
Partial solution, reduce the pump velocity?
Total solution, calculate the net positive suction head available so the
pressure at the suction side of the pump were always positive?

Do I get the job? :)

Anyway, thanks for your input Dr. Skip.
