Is necessary to install the relief valve after the volumetric pump?
I've the max punp discharge at 4.2 bar g and the design pressu re of pipe is 10 barg. Is it possible that the pressure arrive at the pressure design

However, the valve could also be for minimum flow...

If so (i.e. pump curve quasi-vertical), then safety valve should be installed at the pump discharge.
This is because in case of blocked outlet scenario (no flow = no frictionnal pressure drop), the pump developped pressure will increase until it overcomes the pressure drop for which it has been designed. Indeed, this type of pump is not dead-headed like a centrifugal pump.
I propose:
- Set pressure = 10 barg
- Relieving floware can be assumed equal to the rated flowrate of the pump.
