る請求項１記載のキヤンドモータポンプ。[Scope of Claim for Utility Model Registration] (1) A shaft of a rotor shaft that introduces a liquid equivalent to the pump handling liquid from the outside into the rear rotor chamber of the canned motor section and communicates this liquid between the front rotor chamber and the pump section side. In a canned motor pump configured to lubricate the bearings and cool the motor section by leading to the pump section through a gap between the through-holes, the bearings provided on both sides of the motor rotor and the respective ends of the motor rotor Conical adapters are closely arranged in the spaced apart part, and the large diameter ends of these conical adapters are made to substantially match the outer diameter of the motor rotor, and the small diameter ends of the conical adapters are made to substantially match the outer diameter of the bearing, and are fixed to the rotor shaft. Canned motor pump. (2) Thrust washers are disposed to face bearings provided on both sides of the motor rotor at portions separated from each end of the motor rotor, and conical adapters are tightly provided between the thrust washers and each end of the motor rotor. 2. The canned motor pump according to claim 1, wherein the large diameter ends of these conical adapters are made to substantially match the outer diameter of the motor rotor, and the small diameter ends of the conical adapters are made to substantially match the outer diameter of the thrust washer.
