The FHJ type desulfurization pump is a new generation of high-efficiency series desulfurization pumps developed by our company based on the successful design and manufacturing experience of corrosion-resistant and wear-resistant slurry pumps, and tailored to the characteristics of pumps used in China's flue gas desulfurization industry (limestone, gypsum wet desulfurization, double alkali desulfurization, circulating fluidized bed desulfurization, seawater desulfurization, ammonia desulfurization and other processes), absorbing advanced technologies from similar products at home and abroad. The high flow rate of the pump can reach 18000m3/h, and the head of the pump is generally below 50m, covering all pump operating conditions for desulfurization systems. It is suitable for large slurry circulation pumps, slurry pump pumps, and sludge pump pumps in absorption towers. There are mainly two forms of desulfurization pumps: vertical and horizontal.
