Introduction
Model DG boiler water circulation pump is a horizontal multistage centrifugal pump and suitable for transporting pure water (solids diameter less than 1%) and other liquids of both physical and chemical natures similar to those of pure water.
DG model middle and low pressure boiler water pump supply pump is applicable to transport medium with temperature of not higher than 150℃, and is also applicable for small boiler water supply or transporting medium similar to hot water.
DG model Hot Water Multistage Pump for Metallurgy Plant is applicable for small boiler water supply or transporting medium similar to hot water.
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.
These are designed to run direct or through pulley with an engine/motor with a minimal variation in efficiency.
These pumps are designed for boiler feed, dewatering in mines, fire fighting.
