Line Pressure Drop

(OP)
Dear Fellows need your help. if we have two pumps in series one is delivering at 6-9 bar and on same header i have one pump for an other system which need 2-3 bar suction. one way is to use PCV but i dont have time to as lead time is very long. i want to commission a system. How do i run this pump at 2 bar.

RE: Line Pressure Drop

if you want to run the first pump at a lower rpm to reduce the pressure can you put it on a vfd?
