Material selection for pumps handling corrosive substances

Thread Content

98% sulfuric acid, 48% liquid caustic – transported by magnetic pumps; is it necessary to line the tank with plastic? If lining is used, can stainless steel be used for lining? Lined with PTFE? If the lining peels off, is the pump then rendered unusable? If not, what material should be chosen (304? 316L? Or something else? ）

Sulfuric acid uses PTFE lining, while alkalis do not

No lining is required; ordinary carbon steel is sufficient. However, a jacket or heat tracing is needed to prevent freezing in winter, which could damage the pump components.
