Desulfurization Pump Features
The DT series desulfurization pump is a single-stage, single-suction, horizontal centrifugal pump, mainly used as an absorption tower circulating pump in wet FGD systems. It features a wide flow range, high efficiency and energy saving, simple structure, and convenient maintenance. This series of pumps is equipped with a compact X-type bracket, which can greatly save space. At the same time, our factory has developed a variety of new materials for desulfurization system pumps to meet the needs of various operating conditions in power plants.
Desulfurization Pump Structure
In the rubber pump structure: The impeller, suction cover, and front guard plate are made of special wear-resistant materials. The front casing, rear casing, and rear guard plate are made of natural rubber, which has excellent natural wear and corrosion resistance, is lightweight, and relatively low in cost. In the metal structure: The impeller, casing, front guard plate, and rear guard plate are made of special wear-resistant and corrosion-resistant materials. The suction cover is cast iron with rubber lining.
Sealing Type: The mechanical seal uses a cartridge-type seal specifically designed for desulfurization processes, ensuring reliable operation.
Transmission Method: V-belt drive, elastic coupling drive, gear reducer drive, fluid coupling drive, variable frequency drive, and thyristor speed regulation, etc. Multiple speeds and various variations are used, allowing the pump to operate under optimal conditions, ensuring a long service life, high operating efficiency, and the ability to meet a variety of harsh conveying conditions.
Application Range of Desulfurization Pumps
A desulfurization pump is a mechanical pump with corrosion resistance, mainly used for conveying corrosive liquids. It is a widely used type of general-purpose equipment pump, with advantages such as good sealing performance, long service life, and wide applicability. Its corrosion resistance, wear resistance, and non-deformability allow it to be used for conveying corrosive clear liquids in industries such as sulfuric acid and phosphate fertilizer, non-ferrous metal smelting, chemical engineering and chemical, and chlor-alkali industries. The application range of desulfurization pumps is extremely wide. Specifically, desulfurization pumps are mainly used in the following aspects:
1. Sulfuric Acid and Phosphate Fertilizer Industry: Mainly used for conveying dilute acid, mother liquor, wastewater, seawater, silica-containing liquids, and phosphoric acid slurry.
2. Non-ferrous Metal Smelting Industry: Mainly applicable for conveying various acid solutions, corrosive ore pulps, electrolyte pulps, and wastewater in the hydrometallurgy of lead, zinc, gold, silver, copper, manganese, cobalt, and rare earths.
3. Chemical and Other Enterprises: Mainly used for conveying sulfuric acid, hydrochloric acid, alkaline, and oil clear liquids or slurries, as well as various dyes and pigments in titanium and iron production.
4. Chlor-alkali Industry: Mainly used for conveying hydrochloric acid, liquid alkali, and electrolytes.
5. Water Treatment Industry: Mainly used for conveying pure water, ultrapure water, and various wastewaters.
6. Iron and Steel Enterprises: Mainly used for conveying sulfuric acid, hydrochloric acid, and wastewater with impurities in pickling systems.
7. Coal Industry and Coal Chemical Industry: Mainly used for conveying corrosive liquids and coal slurry, as well as auxiliary pumps for coal washing and selection wastewater.
Desulfurization pumps use high-strength, wear-resistant materials for flow components, suitable for conveying strongly abrasive, high-concentration, and large-particle slurries. They can be used in multi-stage series within the pump's larger operating pressure range.
Depending on the medium being pumped, desulfurization pumps have interchangeable flow components of various materials, suitable for conveying abrasive or corrosive, large-particle or fine-particle slurries.

Structure of pumps with a diameter of 400 mm or more: The pump body is connected to the suspension body. The medium end uses a single row of cylindrical roller bearings to bear radial force, while the drive end uses a single row of cylindrical roller bearings and a single row of four-point contact ball bearings to bear radial and axial forces. The impeller is locked by the impeller cover structure, and the clearance between the impeller and the wear plate is adjusted by an axial adjustment device.
