PROBLEM TO BE SOLVED: To provide a canned motor pump in which solidification of liquid is prevented while enabling long service life in a canned motor pump handling liquid with a high solidification point. SOLUTION: In the canned motor pump, an impeller 2 is attached to one end of a rotor 5, and the rotor 5 is supported by bearings 9a, 9b disposed on both of an impeller side and a side opposite to the impeller. A first jacket 15 with a hermetic structure is brought into close contact with an outer periphery 13a of a stator 13, and a second jacket 16 with a hermetic structure brought into close contact with an outer periphery of the first jacket 15.
