How to manage a broader range of pressure? | Xylem China

2020-7-27 · For systems where boiler pressures are greater than 50 psi, your discharge pump pressure needs to be greater than the losses by a minimum of 10 psi, in order to be on the safe side. If we run the unit under vacuum then another 5 psi should be added on top of the above rule, since the pump will be pumping out of an average of negative 5 psi.
