Packing and dispenser system for formulation of multi-constituent viscous substances, has dosing pumps attached to components and exhibiting sucking side that communicates with storage vessels, and check valves provided in inlet of mixer

摘要

The system has storage vessels (10a, 10b) for separate storage of two components. Dosing pumps (12a, 12b) are attached to each component, and exhibit a downstream pressure side, an operatable pump head and a sucking side that communicates with the storage vessels. An opening region is arranged downstream to a mixing zone of a mixer. Check valves (40a, 40b) are provided in an inlet of the mixer. The dosing pumps exhibit intake valves (16a, 16b) that are divided into a sucking side upstream of the dosing pumps and into a pressure side downstream of the dosing pumps.
