DG series boiler feedwater pump

This series of pumps is a single suction multi-stage segmented centrifugal pump used for conveying clean water and other liquids with physical and chemical properties similar to water. The maximum temperature of the conveying medium is 160 ℃, mainly used for boiler feedwater and mine drainage. This series of pumps adopts excellent hydraulic models and structural design methods, therefore, its advanced structure and high efficiency and energy saving are significant features. The 100DM100 drainage pump has a slightly different structure. Its inlet is in a horizontal direction, while the DG series pump has a vertical upward inlet and outlet, with the same performance as the 100DG and a maximum head of 1000 meters. Suitable for mine drainage. This series of pumps complies with the following standards: GB5659-85 "Technical Conditions for Multi stage Centrifugal Pumps", Q/BBC003-91 "Boiler Feed Water Pumps", etc. For specific model parameters, please click on the download link/upload/file/20200613/2020061372551_25971.docx
