ZT series desulfurization pump has axial suction, single-stage single-suction and cantilever centrifugal structure. The series of pump is innovated by comprehensively utilizing advantages of like products at home and abroad based on hydraulic design, structural design, and materials of flow passage components. It is featured by high efficiency, energy conservation, wear resistance, corrosion resistance, low vibration and noise, reliable operation, long service life and so on, and its combination property is advanced. It is widely used for conveying limestone or gypsum slurry of desulfurization systems in thermal power generation, aluminum refining, oil refining, and other industries. The allowable maximum weight concentration of conveyed slurry C w is 60%, chloridion content of slurry can reach 60,000ppm maximally, PH value of slurry is allowed between 2.5 and 13, and slurry temperature is less than or equal to 65℃.
