Selection of materials for chemical pumps
Thread Content
Could everyone please help determine what material would be suitable for this pump? Thank you????
The actual operating temperature should be higher than 70–80°C; at such high temperatures, fluoroplastic F46 and polymers struggle to perform well, especially the impellers.
Right. I have used both materials. No.
Use duplex stainless steel 2205 2207
Duplex steels and nickel-based materials. For more information, please follow the official account “Chemical Equipment Innovation Base””
316L is steel resistant to boiling sulfuric acid. 2205 duplex steel can tolerate a small amount of chloride ions; non-metallic materials are not recommended when solid particles are present as they lack wear resistance – ceramic pumps should be considered in such cases
