Magnet coupling arrangement for centrifugal pump

摘要

The magnet coupling system is for the centrifugal pump having drive-side rotor carrying magnets (8) on its inner face and an output-side rotor (7) carrying magnets on its outer face, together with a split-can (9) between the rotors (6,7). The adjoining surfaces of the rotors (6,7) and the magnets (8) have a mutually matching contour (shape). The rotors are manufactured by a sintering process and are specifically formed by a basic body (14 or 15) and one or more sintered rings (16 or 17) serving to receive the magnets (18 or 19).
