A boiler feed water pump is a unique type of pump employed to pump feed water to a steam boiler, which is known as a dry boiler or hot water boiler. The water obtained from the boiler may be returning condensate created due to the heating of the boiler or fresh water supplied from a well, etc. The amount of water produced is dependent upon the temperature of the boiler and the atmospheric pressure at the point of origin. The boiling point of water is also dependent on atmospheric pressure. Boiler feed water pumps are commonly used for heating water and industrial purposes.
A special type of boiler feed water pump system is generally installed in boilers. It helps in reducing vibrations that are caused by passing of boiling vapors through cooling tubes.

These cooling tubes are generally made of stainless steel. They help reduce the vibrations, which is one of the causes for an increase in heat loss in boilers.
A Between-Borne Insulation is also referred to as BIFO (Between-Bed and Overhead Oxygen Flux) and is used as insulation between the boiler feed water pump assembly and the venturi air gap. A high density foam is usually applied between the air gap and the boiler feed pipe. This creates a protective air layer between the boiler feed pipe and the air gap and helps in the prevention of moisture escape.
Venturi stainless steel pumps are commonly used in boiler feed water pump systems. Vented air-gap stainless steel pumps are also available; however these are more appropriate for use in conjunction with the air-gap venturi filters. The flow of air and its exit into the boiler chamber will remain constant, hence there is no leakage.
In addition to the above mentioned components, the boiler pump and associated accessories will be required for proper boiler operation. They should be selected based on their expected usage. For example, if it is used for hot water heating, then suitable pumps will have high efficiency; high temperature requirements and should have minimum restriction in speed. Pumps should also be designed to handle heavy pressure. This is especially true for those used for pumping treated wastewaters such as oil and liquid coal. Otherwise, the boiler pump may damage the boiler casing and restrict boiler operation.
There are various types of boiler feed water pumps available in the market today. Some of them have variable speed motors, while some others are rotary screw pumps. The main principle of functioning of such boilers is the generation of sufficient stream of steam or hot water to make the working of the appliance faster than the normal speed.
