PTFE centrifugal pump Manufacturer

     First, it is necessary to have a detailed understanding of the chemical substances that need to be transported in the chemical plant. This includes information such as the name, chemical formula, concentration, and pH value of the chemical substances. At the same time, it is also necessary to consider whether the chemical substances are oxidizing, reducing, or containing solid particles.      Second, according to the properties of the chemical substances, select appropriate pump body, impeller, and sealing materials. Generally, a ptfe centrifugal pump can be chosen. Its pump body is lined with fluoroplastic (polytetrafluoroethylene). Or a PTFE centrifugal pump can be selected. Its pump body is lined with PTFE. For sealing materials, when transporting organic solvents, mechanical seals can be used. The sealing surface materials can be selected as silicon carbide-silicon carbide (SiC-SiC) pairing. This material combination has good wear resistance and chemical corrosion resistance and can effectively prevent organic solvent leakage.      Third, according to the flow and head requirements calculated according to the production process requirements of the chemical plant, select the appropriate model from the product catalog of the manufacturer of chemical corrosion-resistant centrifugal pumps. For example, the CYH Series Stainless Steel Chemical Centrifugal Pump produced by Anhui Changyu Pump Valve Manufacturing Co., Ltd. is a chemical corrosion-resistant centrifugal pump. Its flow and head range can meet the requirements of various chemical productions. Its rated performance points and overall dimensions are marked in accordance with the international standard IS02858-1975(E). It is an energy-saving product that replaces F-type corrosion-resistant pumps.      Finally, consider the transportation temperature and system pressure of chemical substances. Some materials may lose their corrosion resistance at high temperatures. At this time, it is necessary to select a centrifugal pump that is both high-temperature resistant and corrosion-resistant. For example, the CYF Series Fluoroplastic Centrifugal Pump produced by Anhui Changyu Pump Valve Manufacturing Co., Ltd. is a chemical corrosion-resistant centrifugal pump. Its flow and head range can meet the requirements of various chemical productions. It can continuously transport strong corrosive media such as sulfuric acid, hydrochloric acid, hydrofluoric acid, nitric acid, aqua regia, strong alkali, strong oxidant, organic solvent, and reducing agent of any concentration at a temperature range of -85°C to 200°C.
