Abstract (en)

[origin: DE19940399A1] The invention relates to a device for transporting polymer dispersions. Said device can be driven by a drive system and is configured in the form of an impeller (28). Said impeller can be surrounded by a housing or project freely into the polymer dispersion contained in a reactor vessel. A number of blades (2) are arranged in the area of the hub (1) of the impeller (28) in such a way that the polymer dispersion flows evenly through the pump chambers (5, 25) on the front side (7) and the rear side (8) of the impeller (28).
