Desulfurization pumps are corrosion-resistant pumps, mainly used for the transportation of corrosive liquids. It is a widely used pump among general equipment pumps. The desulfurization pump is usually a horizontal cantilever single-stage single-suction centrifugal pump, which is specially designed and developed for transporting corrosive media containing fine particles. The flow material of the desulfurization pump is required to be wear-resistant and corrosion-resistant.
