PURPOSE: A magnetic rotor and a rotational pump with the same are provided to prevent the rotor from being frequently replaced by protecting a permanent magnet from factors damaging fluid and gas substances of a target fluid. CONSTITUTION: A magnetic rotor(1) comprises a permanent magnet(8). The rotor can be operated by being floating by magnetically non-contact type inside a pump housing(4) in the inside of a stator(5) of a rotation pump(2) in order to deliver fluid(3). The rotor is continued in the inside of an external capsule unit(6) including hydrofluorocarbon. The permanent magnet is covered on a metal jacket(7) in the inside of the capsule unit. The metal jacket includes at least one element of a group consisting of tantalum, niobium, zirconium, titanium, hafnium, gold, platinum, palladium, osmium, iridium, ruthenium, and rhodium. |
