Multistage Hot Water Boiler Feed Water Pumps

A Boiler Feed Water Pump is a specific type of pump used to pump feed water into a steam boiler. Our High Pressure Boiler Pumps are high pressure units that take suction from a condensate return system and can be of the centrifugal pump type or positive displacement type.

Product Details

Multistage Hot Water Boiler Feed Water Pumps

The DG series commercial and industrial hot water boiler feed pump is a horizontal multistage centrifugal pump, suitable for transporting pure water and other liquids whose physical and chemical properties are similar to pure water. Meanwhile, it is also applicable to water supply for small boilers or transporting hot water-like media, with a maximum temperature of up to 150℃.

Applications of Hot Water Boiler Pumps

Long-range water conveyance
Supply and transfer of boiling water
Pressure boosting in water systems
Agricultural irrigation operations
Water supply for mining activities
Fire-fighting systems
Offshore engineering projects
