F-TL desulfurization pump is a new generation high-efficient desulfurization pump based on the successful design experience of ZM series slurry pump. It absorbs domestic and foreign advanced technology of the same type products and is designed aimed at flue gas desulfurization pump properties in our country. Its maximum flow range reaches 12000m3/h. Its lift is normally below 100m, covering all desulfurization system pump working conditions. It can be used as absorbing tower large-scale slurry circulating pump or limestone slurry transporting pump, gypsum slurry discharge pump, recovery pump and pit pump etc.
