Claims

[Claims for Utility Model Registration] 1. A corrosion-resistant non-leakage pump in which an impeller rotates due to the magnetic rotation of a driven magnet fixed to a sleeve integrated with the impeller as the drive magnet rotates, sucking in and pumping fluid. - A driven magnet is fixed to the outer circumference of the sleeve, a heat-shrinkable resin cylindrical body is fitted to the outer periphery of the sleeve in front and behind the driven magnet, and a ceramic cylindrical body is shrink-fitted to the outer periphery of the sleeve. Fitted□
A corrosion-resistant, leak-free pump characterized by a driven magnet that is liquid-tightly sealed. -2 Corrosion-resistant leak-free pump according to claim 1, wherein the heat-shrinkable resin cylindrical body is made of fluororesin. '3 A utility model in which a concave groove is provided in a direction perpendicular to the axis of the sleeve on at least one of the outer circumferential surface of the sleeve or the inner circumferential surface of the ceramic tube that faces the heat-shrinkable resin tube between them. Corrosion-resistant leak-free pump according to claim 1 or 2. 4. The corrosion-resistant, leak-free pump according to claim 1, 2, or 3, wherein the driven magnet is coated with a resin before the ceramic cylindrical body is fitted into the sleeve.
