The invention relates to an impeller of a centrifugal pump, comprising atleast twoblades (4) for conveying media containing solids. According to the invention,the bladeleading angle (.beta.1) is smaller than 0°. The blade angle (.beta.)increases in a first section (9)until a value of 0° is reached. In a second section (10), anotherincrease occurs until amaximum value is reached. In a third section (11), the blade angle (.beta.)decreases again.
