Brass is an alloy of copper and zinc, which has good processability and corrosion resistance. Brass impellers are easy to machine and have high strength and wear resistance during the manufacturing process. In addition, brass also has good thermal and electrical conductivity, which enables brass impellers to maintain stable working performance in high temperature and high pressure environments. Therefore, brass impellers are commonly used in applications that require high machining performance and corrosion resistance, such as water pumps, fans, etc.
The lifting and discharge of liquids by submersible pumps are achieved by the rotation of the impeller driven by the electric motor drive shaft. The selected submersible pump impeller form and material vary depending on the liquid being transported.
The materials of submersible pump impellers mainly include five categories: cast iron impellers, aluminum alloy impellers, brass impellers, stainless steel impellers, plastic impellers, etc. Neutral liquids generally require cast iron impellers, brass impellers should be used for oil, and aluminum alloy impellers, stainless steel impellers, or plastic impellers should be used for sanitary and food grade fluid materials. Corrosive liquids should be more corrosive, and brass impellers, stainless steel impellers, and plastic impellers should be selected.
