A canned motor has a thin partition wall for separating the rotor, and the rotating shaft is supported by sliding bearings attached to the center of the motor case end face and the bracket face on both ends of the rotor. In the pump,
The slide bearing is connected to the motor case end surface and the bracket through a tolerance ring housed in a storage groove with a rectangular cross section that is bored in the inner diameter surface of a through hole formed in the center of each of the motor case end surface and the bracket surface. A bearing structure for a canned motor pump characterized by being installed at the center of each surface.
