High-Efficiency Flue Gas Desulfurization Circulating Pump - Leading China Suppliers & Factory Solutions
The Manfre series of desulfurization circulating pumps have reached the energy efficiency standard energy-saving evaluation requirements, and the energy-saving effect is obvious. The products meet the requirements of safety, quality and environmental protection standards, and have been selected into the recommended catalogue of energy-saving electromechanical equipment (products) of the Ministry of Industry and Information Technology.
The pump is of all metal structure, the pump body is made of ultra-low carbon nitrogen-containing duplex stainless steel CD4MCuN, the impeller and wear plate are made of high-chromium wear-resistant alloy Cr30A, which has excellent corrosion resistance and wear resistance and long service life.
The pump is a single volute, single-stage, single-suction centrifugal pump, “back-pull” structure. When disassembling the impeller, mechanical seal, shaft and other components, it is not necessary to disassemble the pump inlet and outlet pipelines, and the maintenance is convenient.
Generally, the single-end cartridge mechanical seal is adopted, which is convenient for disassembly and assembly. The impeller is designed with a balance hole to prevent large particles from contacting the mechanical seal.
The axial adjustable structure design makes the impeller easy to adjust, keeping the gap between the impeller and the front pump cover and the wear plate, thus maintaining the high efficiency of the pump.
The pump shaft is a large diameter and short shaft head, which can reduce the deflection of the shaft during operation and prolong the service life of the seal.
The impeller and the shaft adopt double-key connection and double locking device, which solves the problem that the impeller reverses and falls off during shutdown and backwashing.
Lubricated bearings with thin oil, oil level mirror and constant oil cup can ensure sufficient lubrication; safe and reliable labyrinth dust disc can effectively prevent dirt and impurities from entering and prevent oil leakage.
The pump body features an all-metal structure constructed from ultra-low carbon nitrogen-containing duplex stainless steel CD4MCuN. The impeller and wear plate are made of a high-chromium wear-resistant alloy (Cr30A) to ensure outstanding corrosion and wear resistance.
The "back-pull" structure allows operators to disassemble the impeller, mechanical seal, shaft, and other internal components without having to disconnect the pump's inlet and outlet pipelines, making maintenance fast and convenient.
The pump utilizes a single-end cartridge mechanical seal that is easy to assemble. To protect it, the impeller is specifically designed with a balance hole that prevents large particles from contacting and damaging the mechanical seal.
Thanks to its axial adjustable structure design, the impeller can be easily adjusted to maintain the correct gap between the impeller, the front pump cover, and the wear plate. This adjustment capability ensures long-term high efficiency.
The pump shaft and impeller are connected using a double-key system and a double locking device. This mechanism prevents the impeller from reversing and falling off during shutdown or backwashing procedures.
Yes. The Manfre series of desulfurization circulating pumps meet the energy efficiency standard energy-saving evaluation requirements and have been selected for the recommended catalogue of energy-saving electromechanical equipment by the Ministry of Industry and Information Technology.
