- Control of water pressure in closed loop system with a pump.

How can we control the pressure of the water inside a closed loop system (chiller system for example)?

Let´s say, we have a pump curve and an system resistance curve that can be modified (through opening or closing some valves)

In everywhere, what I see is that the intersection of the system curve with the pump curve marks the operating point of the system.

My question is, at the operating point, what´s the water pressure in the closed system? I would say that it is 0 barg everywhere as the energy given by the pump is cancelled out by the resistance. If that is right, what can we do if we want the system pressure to be 2 barg (we want the water to be pressurized)?

Thanks!
