Boiler water pump:

DG boiler water pump is a self-balancing horizontal multilevel boiler feed pump with single-suction, multilevel and sectional structure. with their wide rang e and high efficiency, sound cavitation performance, smooth operation and little wearing parts, ther reliability is greatly improved and maintenance cost of user is greatly reduced, hence life running cost of pump is reduced.
this series of pumps are suitable for medium and low pressure boiler water feeding, and high-pressure boiler water feeding for thermal power plant, as well as high-lift water supply and drainage of factories and cities. They are used in transferring water or other liquid with similar physical and chemical properities to water. Temperature of media being transferred can vary from -20C to 160C.
