Claims

[Scope of Claim for Utility Model Registration] 1. In a portex pump having a volute chamber with a space between the open front surface of one side of the impeller and the suction port, and a casing configured to include a discharge port communicating from the vortex chamber. , the ridgeline shape of the blade tip of the impeller blade is a convex curve toward the spiral chamber so that the inlet part touches the front surface of the blade, and the front surface of the blade is a line that smoothly continues to the inlet part of the blade, and the cross section of the blade inlet part is is a portex pump with an impeller in which the blade tip is connected smoothly between the blade surfaces with a convex shape, and the blade root is connected to the vane plate with a concave curve. . 2. A practical impeller having a shape in which the cross-section of the inlet part gradually changes from the middle of the inlet part to a position where the rear part and the front part of the blade are continuous, and then changes and transitions to the cross-section of the front part of the blade. A portex pump according to claim 1 of the patent registration claim.
