Boiler Feed Pump - an overview | ScienceDirect Topics

additional pressure required at the cleaner inlet. To do so would reduce the flow and that is not acceptable. You must deal with this during the initial stages of design or if the installation is already in operation modify the pump. The pressure required (30 psig) at the cleaner inlet corresponds to (use equation [1]) 69 feet of pressure head.
