Patent number: 9239056Abstract: A non-clogging type pump impeller includes: a fluid passage provided in an approximately cylindrical body and connecting a suction port to a discharge port. The fluid passage has a vortex shape as viewed from an axial direction. A first recess, which is sunk downwardly in the axial direction, is formed on a first end surface of the approximately cylindrical body so as to surround a boss.
