1, Stainless steel material
Stainless steel has good corrosion resistance and high temperature characteristics, which can resist the erosion of corrosive media such as seawater and sediment, and meet the requirements of harsh environments in deep wells. In addition, stainless steel material can withstand high temperatures and is suitable for certain high-temperature applications. However, stainless steel impellers are relatively expensive, heavy, and difficult to move.
2, Bronze material
3, Fiberglass material
Fiberglass material is lighter than stainless steel, bronze and other materials, making it easier to move. Meanwhile, fiberglass has good corrosion resistance and is not easy to rust or corrode. However, fiberglass material has relatively low strength, is prone to breakage in extreme cases, and has poor heat resistance, making it prone to failure in high-temperature environments.
4, Cast iron material
Cast iron is an inexpensive metal material with relatively low cost. It has good wear resistance and can meet certain requirements for use. However, cast iron has poor corrosion resistance and is prone to damage or failure of pump impellers due to corrosion. It also has poor thermal conductivity and is not suitable for high-temperature applications.
