Aluminium Alloy Pneumatic Diaphragm Pump Sewage Impurity Resistant

Stainless steel material; 304, 316, 316L stainless steel has extremely strong corrosion resistance, high temperature resistance, wear resistance, and sanitary characteristics. It is suitable for general corrosive acidic and alkaline liquids, as well as liquids such as food, drugs, cosmetics, etc. It cannot transport highly corrosive liquids such as sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, etc.

Aluminum alloy material; It has mild corrosion resistance and cannot be used for halogenated liquids. It is suitable for adhesives, water-based coatings, oils, organic solvents, ceramic glaze water, etc.

Cast iron material; It has high strength, hardness, wear resistance, and is not corrosion-resistant, suitable for non corrosive liquids. For example: sewage, sludge, mud treatment, oil media, etc

Perfluorinated material/PVDF; PVDF has strong toughness and excellent aging resistance. Its corrosion resistance is suitable for chemical, electronic, petrochemical, solvent transportation, electroplating cleaning solutions, nitric acid, waste acid, and corrosive acids.
