Abstract
A permanent magnet canned motor pump features in its corrosion-protection housing which comprises a reinforced bracket, motor casing and a motor rear casing. The reinforced bracket is made of corrosion-resistance plastic and the motor casing and the motor rear casing are made of aluminum alloy. Accordingly, the corrosion-protection housing is capable of preventing the corrosion of the chemical liquid to the aluminum alloy components. Beside, the permanent magnet canned motor pump provides a heat dissipation mechanism while meeting the structural need of the corrosion-protection housing, so that the motor can dissipate heat in a sufficient rate.
