Abstract
L'entrée concerne une pompe centrifuge à roue à aubes ouverte dont l'axe de rotation est vertical et dont les aubes sont situées à une distance relativement importante de la paroi opposée de la pompe constituant l'entrée dans la pompe. Une ou plusieurs ailettes 3 aménagées sur la paroi faisant face à l'entrée 4 dans la pompe, s'étendant jusqu'à proximité du rebord avant de la roue à aubes 2, sont situées à une faible distance radiale de la périphérie de la roue à aubes 2.
