Abstract

Improvements in centrifugal pumps for the transport of liquids with a high gas content, especially for emulsified fermentation media, with holes in the disc of the impeller hub and with blades on the rear side of the hub disc, characterized in that the holes in the hub disc are arranged in the vicinity of the suction side of the impeller blades, starting at the start of the blades, decreasing its cross section continuously preferably from the start of the blades to the proximity of the end of the blades and/or or increasing its separation continuously preferably from the start of the blades to the proximity of the end of the blades, and so that the cross section of the impeller decreases further in the direction of the current in relation to the design for the transport of pure liquids.
