It’s too general. The selection of a pump is mainly determined by process parameters such as head and flow rate, which help in choosing the appropriate type. As for what you mentioned, it specifically comes down to choosing the material.
Mixed acids are highly corrosive; a steel-lined PTFE option can be considered, and it can basically be used at temperatures of 170°C； Or consider acid-resistant ceramic pumps. The flow rate and head can be selected as needed.
I agree with what was said on the third floor; it’s best to use fluorine-lined pumps. At this temperature, there are no major issues, and nowadays there are steel-fluorine-lined pumps available which offer good performance. It’s also a good idea to consult reputable fluorine pump manufacturers, such as Jiangsu Jiangfeng Fluorine Pumps.
Mainly, it’s a matter of considering the materials to prevent corrosion; by using special materials, there should be no problem
You haven’t provided specific parameters such as flow rate and head. Based solely on your medium and temperature, you can choose a fully perfluoroelastomer centrifugal pump or a magnetic pump with a polytetrafluoroethylene lining.
Centrifugal pumps with PTFE lining can be selected.
From the perspective of corrosion resistance, it must be steel-lined with PTFE
Steel-lined PTFE centrifugal pump – the preferred choice from Wolong Pump & Valve. If LZ wants to learn more, contact me via Q. The employees at Wolong are dedicated to serving you. Wolong pumps and valves: corrosion and leak prevention, completely rust-proof
