Claims

[Scope of utility model registration request]

A vortex flow pump in which an impeller is attached to a pump shaft passing through a casing, and the impeller is rotatably housed between the casing and the casing cover, and the impeller is movable in the axial direction of the pump shaft. At the same time as mounting, an annular communication groove is formed along the circumferential direction of the impeller on the contact surface between one side of the impeller and the casing and the contact surface between the other side of the impeller and the casing cover, and A swirling flow pump characterized by being provided with a pressure introduction path that communicates these communication grooves with a high pressure section such as a pump flow path.
