The heat shield was used to isolate the heat from pump to motor for protection purpose. Construction of the air-water cooled heat shield was design in accordance with the axial dimension and requirement of saving materi-als. The raw materials were decreased while the axial di-mension of pump set was reduced, to improve the reliability of screened pumps operating under high temperature and pressure.
