。 The pump impeller is integrally attached to the rotor made of permanent magnets of the canned motor, and a thin partition wall is provided between the motor stator and rotor to watertightly isolate the stator side from the rotor side. In a canned motor pump having a structure in which a part of the pumped liquid is circulated to the rotor side, the motor is an external rotor type motor in which the rotor rotates on the outer circumferential side of the stator, and a rotor support plate that supports the rotor. A canned motor pump characterized in that the impeller is integrally attached to an end face of the pump, and the partition wall is formed of a non-magnetic stainless steel plate.
