In the selection of fluorine-lined magnetic drive pumps, different lining materials directly impact the pump's performance and suitability for different environments. This article delves into the differences among PP, PVDF, FEP, and PFA, aiding you in making informed choices for your specific pump needs.

Ⅰ.PP (Polypropylene)

Characteristics: Good chemical stability, strong corrosion resistance, suitable for general corrosive media.

Applications: Suitable for handling media with lower acidity, lower alkalinity, and moderate temperatures, such as cleaning solutions and water treatment.

Ⅱ.PVDF (Polyvinylidene Fluoride)

Characteristics: Excellent corrosion resistance, outstanding mechanical properties, suitable for highly corrosive media including strong acids and bases.

Applications: Widely used in industries like chemical processing, electroplating, and semiconductor manufacturing where high corrosion resistance is crucial.

Ⅲ.FEP (Fluorinated Ethylene Propylene)

Characteristics: Superior corrosion resistance, excellent non-adhesive properties, high-temperature resistance.

Applications: Suitable for corrosive media such as acids, bases, and organic solvents, while also capable of handling high-temperature liquids.

Ⅳ.PFA (Perfluoroalkoxy)

Characteristics: Excellent corrosion resistance, exceptional heat resistance, extremely high chemical stability.

Applications: Widely applied in chemical, electronic, and pharmaceutical industries, especially in situations requiring high purity and corrosion resistance.

Ⅴ.Selection Recommendations

For general corrosive media: PP is a viable choice.

For strong acids and bases: PVDF is recommended.

For high-temperature liquid handling: Both FEP and PFA are ideal, with PFA being more suitable for extreme conditions.
