It can't be stressed enough, water and the right amount of it is critical for the boiler's operation. Kind of a no-brainer right? There are a lot of factors however that affect the selection of a boilers feed pump. Boilers, especially those with a deaerator or systems designed as a mobile boiler or temporary system require a pump that is specially designed to deliver a lower net positive suction head then a conventional centrifugal feed pump. The wrong pump or neglect will lead to a condition known as cavitation which is identified by excessive vibration, poor flow and pressure, and of course the classic sound of marbles or sand inside the pump casing. The failure of the pump is inevitable if cavitation is not addressed.
