ABSTRACT:
A pump for viscous substances is constructed in such a way that it is constructionally simple and insensitive to foreign bodies. For this purpose, a plurality of shafts which are rotated in the same direction are arranged in a casing. Disks are fitted to the shafts and these disks are substantially clearance-free with respect to the corresponding wall portion of a recess and an adjacent shaft. At least one such disk and at least one adjacent shaft and the associated wall portion of a recess define a chamber. A plurality of such chambers are arranged in series and are interconnected by in each case an overflow duct.
