Claims

[Scope of utility model registration request]

A pump case consisting of a first and second pump case that can be divided into upper and lower parts, an impeller that is rotatably provided inside the pump case, and a pump that extends radially from the center of the impeller around the impeller. In a brushless cascade pump having vanes arranged perpendicularly to the case, a portion of the vanes of the impeller close to the inner surface of the pump case, from the front end to the rear end with respect to the impeller rotation direction. A cascade pump characterized by having a notch cut out diagonally on the opposite side.
