When it comes to chemical pumps, they are more and more widely used in industrial production, especially in the field of chemical industry, corrosion-resistant chemical pumps are increasingly playing an important role. Generally speaking, due to the particularity of chemical pump using environment, it is usually made of metal or fluoroplastic F46. For general metal, its structure is extremely prone to corrosion. External environment such as temperature, humidity and air will directly lead to corrosion of metal. Therefore, the common materials of corrosion-resistant chemical pump are stainless steel and fluoroplastic F 46 both.
