きポンプ。[Claims for Utility Model Registration] A pump casing having a pump chamber that communicates with a suction port and a discharge port, and a side end wall forming a part of the pump chamber, which is arranged to face a side end wall at a predetermined distance. A volute comprising a disk and a resin disk rotor having blades integrally formed on one main surface of the disk opposite to the side end wall and rotatably held in the pump casing. In the pump, the disk rotor has a ring-shaped protrusion that protrudes toward the side end wall from an outer peripheral edge of the main surface of the disk facing the side end wall, and is integrally formed with the disk. A centrifugal pump characterized in that a space formed between an end wall and the disk is substantially separated from other spaces in the pump chamber.
