ABSTRACT:
The device serves to meter at least two free-flowing components and to convey metered quantities of the components into a mixer in which a reactive compound is formed from the metered quantities. For each component the device contains, as metering and conveying means, in each case at least one pump, a flow meter and a pressure vessel. The pressure vessel is subdivided by a flexible diaphragm into a first part-volume, which in each case receives one of the components, and a second part-volume which can be acted upon by incompressible fluid. When a starting component containing abrasive substances is used, to avoid sedimentation of the abrasive substances during metering and conveying, the pressure vessel which receives the abrasive component is designed and arranged in such a way that the abrasive component fed into its first part-volume rests on the flexible diaphragm.
