Abstract: The present invention relates to a pump. The pump comprises a housing providing a rotor accommodating space and having an inlet channel and an outlet channel which is arranged substantially on the axis of the rotor accommodating space in communication therewith for the passage of fluid. A shaftless rotor is completely and rotatably accommodated within the rotor accommodating space. A stator for magnetically rotating the rotor within the rotor accommodating space is provided. An array of grooves is formed on at least one surface of the surfaces of the rotor and the surfaces of the housing whereby when the rotor is magnetically rotated by the stator, the fluid is forced forward by the grooves. The rotor is radially and axially supported in the rotor accommodating space solely by fluid bearing provided by the fluid and the groove means.
