Abstract

1482017 Centrifugal pumps F HOFFMANNLA ROCHE & CO AG 21 Nov 1974 [25 Jan 1974] 50582/74 Heading F1C A liquid/gas mixture having a gas content of 5 to 30% is pumped by a centrifugal pump having a rotor covered with a perforated ring 3, the holes 4 being distributed in groups each of which lies immediately in advance of a rotor blade 10. The pump outlet 7 may be provided with guide vanes 6.
