<P>PROBLEM TO BE SOLVED: To prevent the corrosion of a constituent component of a permanent magnet canned motor pump caused by a chemical liquid, and to solve a problem of the heat dissipation of a motor. <P>SOLUTION: The permanent magnet canned motor pump is characterized by comprising a corrosion protection housing including a reinforcing bracket, a motor casing and a motor rear casing. The reinforcing bracket is formed of corrosion resistance plastic, and the motor casing and the motor rear casing are formed of aluminum alloys. According to this, the corrosion of the constituent component formed of the aluminum alloy caused by the chemical liquid can be prevented by the corrosion protection housing. Furthermore, the permanent magnet canned motor pump provides a heat dissipation mechanism which satisfies a structural requirement of the corrosion protection housing, and on the other hand, makes the motor dissipate heat at a sufficient heat dissipation rate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
