Abstract

Die Erfindung betrifft eine Kreiselpumpe mit einem in einem Gehäuse rotierend angeordneten Freistromlaufrad, wobei zwischen einer saugseitigen Gehäusewand und dem Freistromlaufrad ein schaufelloser Raum angeordnet ist und die Pumpe mit einer Einrichtung zur Vermeidung des Abreißens der Strömung versehen ist. Gegenüberliegend zu den Laufradschaufeln (4) und an der saugseitigen Gehäusewand (6) ist mindestens ein, in den schaufellosen Raum (7) vorstehendes, ein- oder mehrteiliges, strömungsbeeinflussendes Mittel (10, 17, 20, 26) angeordnet (Fig. 1).
