The invention relates to a centrifugal pump () comprising a pump housing () which is provided with an axial inlet (), an outlet () and a rotor () which is attached in the pump housing () such that it can rotate about an axial rotation axis A. The rotor () is provided with a central boss (), a shaft shield () fastened to the boss (), a suction shield () attached so as to be axially set apart from the shaft shield (), which suction shield () has an axial supply () aligned with the axial inlet () of the pump housing (), and a plurality of rotor blades () which are fastened between the shields (). The radial inner ends () of the rotor blades () are connected to the suction shield () by a substantial perpendicular connection. 11.
