The invention relates to a pumping, cutting and homogenising device and a device for introducing vibrations into liquids to be pumped prior to entry into the pump element. The aim is to reliably support the pumping, especially of slurries with a particularly high dry matter content and with high gas and air fractions. The object of the invention is to create a centrifugal pump unit, universal in its application, by means of an impeller designed with particularly unconventional fluidics and by means of different devices variably fitted to the centrifugal pump. This object is achieved according to the invention in that with a half-open impeller with enlarging impeller outlet the blades are subject to a maximum axial constriction at a diameter which is approximately 2/3 of the impeller outside diameter, the impeller is provided with or without cutting device and a feed screw, known per se, with or without cutting device, is preconnected to the impeller and a vibrator to the feed screw. <IMAGE> |
