CENTRIFUGAL PUMP IMPELLER WITH BLADE ANGLE PROFILE

摘要

The invention relates to an impeller of a centrifugal pump, comprising at least two blades (4) for conveying media containing solids. According to the invention, the blade leading angle (ß1) is smaller than 0°. The blade angle (ß) 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 (ß) decreases again.
