The basic understanding of the selection of magnetic materials is unified in various countries. The working temperature of NdFeB material is lower than 150 ℃, and the working temperature of SmCo material is lower than 250 ℃. Aluminum ferrite can be used for micro-pumps. The pump body material is divided into two categories: metal and non-metal.
Metal stainless steel does not mean that it is stainless for all liquids, it is mainly used for process liquids, precious liquids, ultra-pure liquids that are compatible with it.
Nonmetals are specially developed for corrosive applications. It is divided into 2 cases. One is a pure plastic pump, thermoplastic moulded from pure polypropylene or ethylene fluoride. The second is lining the pump, which is a popular method of lining plastic for corrosion-resistant pumps.
