High-Efficiency Flue Gas Desulfurization Circulating Pump - China Suppliers & Factory Quality
Performance and benefits
Premium Materials & Durability
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.
Back-Pull Structure
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.
Cartridge Mechanical Seal
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.
Axial Adjustable Design
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.
Heavy-Duty Shaft
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.
Double-Key & Double Locking
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.
Optimized Lubrication & Protection
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.
Frequently Asked Questions (FAQ)
Q: What energy efficiency standards do Manfre desulfurization circulating pumps meet?
Manfre desulfurization circulating pumps meet the energy efficiency standard energy-saving evaluation requirements. They comply with safety, quality, and environmental protection standards, and are listed in the recommended catalogue of energy-saving electromechanical equipment by the Ministry of Industry and Information Technology.
Q: What materials are used to construct the pump's wear parts?
The pump features an all-metal structure. The pump body is manufactured from ultra-low carbon nitrogen-containing duplex stainless steel CD4MCuN, while the impeller and wear plate are made from high-chromium wear-resistant alloy Cr30A for superior corrosion and wear resistance.
Q: How does the "back-pull" structure simplify pump maintenance?
The "back-pull" design allows maintenance technicians to disassemble the impeller, mechanical seal, shaft, and other internal components without having to disconnect or disassemble the pump's inlet and outlet pipelines.
Q: What design features protect the mechanical seal from damage?
The pump uses a single-end cartridge mechanical seal for easy assembly. Additionally, the impeller is engineered with a balance hole specifically designed to prevent large particles from contacting and damaging the mechanical seal.
Q: How does the pump prevent the impeller from falling off during shutdown?
The connection between the impeller and the shaft is secured using a double-key connection and a double locking device. This mechanism prevents the impeller from reversing and falling off during shutdown and backwashing operations.
Q: How is the lubrication and dust protection managed in Manfre pumps?
The bearings are lubricated with thin oil, monitored via an oil level mirror and a constant oil cup to ensure constant lubrication. A labyrinth dust disc is also integrated to block dirt and impurities from entering the bearing house while preventing oil leakage.
