PURPOSE: A high-efficiency pump impeller is provided to minimize the pulsation of fluid caused by driving a motor pump by stabilizing a flow of the fluid introduced between blades, thereby reducing noise. CONSTITUTION: A high-efficiency pump impeller (10) is installed on an output shaft of a motor pump pumping fluid. A plurality of spiral blades (13) is formed on the outer periphery of a central joining shaft (12) formed on the center of a disc-shaped body (11). A spiral horizontal unit (13b) is added on an inner end portion of a vertical unit (13a) of the blade. The spiral horizontal unit maintains an intake space (S) for fluid, guides the fluid in a spiral direction between blades, prevents a solid material from being caught when touching the solid material in the outside, and prevents a vortex of the fluid. |
