Abstract

An impeller of a centrifugal pump is provided. The impeller includes at least two blades (4) for conveying media containing solids. An impeller blade leading angle (β1) is smaller than 0°. The blade angle (β) increases in a first section (9) until a value of 0° is reached. In a second section (10), another increase occurs until a maximum value is reached. In a third section (11), the blade angle (β) decreases again.
