Turbo pump with magnetically supported impeller

A pump, comprising:

• a rotating member having blades providing energy to a fluid, having one plane including a plurality of permanent magnets and the other plane including a magnetic member;
• a casing made of a non-magnetic material for housing said rotating member;
• rotation driving means for rotating said rotating member, said rotation driving means being rotatable and including a plurality of magnets opposed to said permanent magnets of said rotating member over said casing, said magnet of said rotation driving means magnetically coupling with said permanent magnet of said rotating member;
• and
• supporting means for magnetically supporting said rotating member in said casing in an non-contacting manner, said supporting means including a plurality of electromagnets opposed to said magnetic member of said rotating member over said casing, said plurality of electromagnets acting in such a way that said rotating member is supported, spaced from said casing.
