Abstract

Bomba (1), en particular bomba centrífuga para transportar sangre, con una rueda de álabes (6) con un eje de rotación (15) y con un canal de flujo principal (23) a través de la rueda de álabes (6) y con un canal de afluencia (29) hacia la rueda de álabes (6) en una carcasa (2, 3), así como con un canal secundario (20) con una abertura de alimentación (21) y una abertura de salida (24), donde la abertura de salida (24) está orientada hacia el canal de afluencia (29), donde: - el canal de afluencia presenta una sección transversal en dirección axial normal al eje de rotación, - el canal de flujo principal está realizado de forma diagonal axial, de manera que durante el funcionamiento un flujo de entrada circula esencialmente de forma axial hacia la rueda de álabes y un flujo de salida circula esencialmente de forma diagonal desde la rueda de álabes, y en donde - la rueda de álabes se apoya físicamente en dirección axial y puede ser desviada radialmente por el eje de rotación, caracterizada por que la abertura de salida (24) del canal secundario está cubierta por un saliente radial de la carcasa de la bomba.
