Claims

[Claims for Utility Model Registration] (1) A vortex pump in which an impeller fixed to a main shaft rotated by a motor rotates within a passage formed by a main body and a cover to increase the pressure of fluid and send it, an impeller configured to apply force to the cover side during rotation; an adjustment fixing member that adjusts and fixes the impeller to an arbitrary position in the axial direction on the cover side of the main shaft; and a cover for the impeller. A vortex pump characterized by comprising a biasing member that biases the side. (2) The vortex pump according to claim 1, wherein the impeller is provided with blades only on one side and is mounted so that the blades face toward the motor. (3) The vortex pump according to claim 1, wherein the biasing member is a spring of a mechanical seal attached to the motor side of the main shaft.
