摘要：A permanent magnet canned motor pumpwith a corrosion-protection housing which comprises a reinforced bracket (9), motor casing (81) and a motor rear casing (82). 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.
