Dosing and mixing installations for the automatic dosing and mixing of reactive resin components, especially for volumetric ratios </= 100: 20, where for n components, 2 . n - 1 dosing pumps (1) are fastened with the pistons (8) and the piston rods (9) in one plane, in parallel on a stiff connecting beam (10). The central dosing pump (2) contains the volumetrically smallest component. The volumetrically largest components are, in each case, divided over two identical dosing pumps (3 and 4; 5 and 6). The volumetric mixture ratio of the components is formed by the sums of the surfaces of the pistons of associated dosing pumps (2; 3 and 4; 5 and 6). With the aid of a collecting piece (14), which contains a valve insert (33), the components are conveyed into the mixer (15). <IMAGE>
