The hot water is rotated in the impeller chamber 24 of the pump housing 21, which is rotated together with the shaft 40 and condensed on the upper side of the shaft 40, divided by the motor and shield 26. In the forced circulation, a curved protrusion 25-1 is formed so that the inflow chamber 25-2 is provided in the center of the inner bottom surface of the impeller 25 on which the shaft 40 is built up, and the protrusion 25 -1) through the plurality of discharge holes 25-2 at equal intervals, through the plurality of distribution holes 27 through the motor can shield 26 into which the shaft 40 is inserted, and the upper bearing ( 33) and a plurality of annular grooves 41 and spiral inlet holes 42 are respectively provided on the upper and lower surface portions of the shaft 40 into which the lower bearing 34 is inserted. In addition, the inlet chamber 25-2 of the impeller 25 and the space 36 of the bearing holder 37 are formed through the guide pipe path 43 of the upper and lower narrow belts in the longitudinal direction in the center of the shaft 40. The hot water is forced to circulate to improve the cooling effect, and the water film is formed between the shaft and the bearing to give the frictional force to improve the rotational force. This prevents the shaft and the rotor from solidifying.
