ンプ。The pump blade and motor are housed in a casing with their rotating shafts directly connected, and a rotor chamber is created by watertightly separating the inner periphery of the stator of the motor and the outer periphery of the rotor with a thin partition wall, and the motor rotates. The rotating shaft, which is integral with the child, is supported by radial bearings at both ends of the rotor chamber, and a thrust ring is provided on the outer periphery of the rotating shaft at the part sandwiched between the pump blade and the motor rotor, and the rotating shaft is opposed to the thrust ring. In a canned motor pump for hot water circulation in which a thrust bearing is provided, the thrust bearing is arranged in two parts so that the contact surface with the thrust ring is divided into two parts, and one of the divided parts has hot water inside. A canned motor pump for hot water circulation characterized by having a temperature-sensitive material that contracts and expands due to heat.
