Abstract

The invention relates to a dosing apparatus with a container having a charging hole for a refill bag with a liquid in the top part, and an outlet in the bottom part. An opening device for the refill bag is fitted above the outlet. A connector leads from the outlet to a downstream pump. A chamber with a level sensor is arranged underneath the reservoir. The reservoir and the chamber are configured so as to be liquid tight, for supplying the liquid without a refill bag. A dosing pump is integrated within the dosing apparatus. A dosing conduit leads from the pump to a point of usage outside the dosing apparatus, and a return conduit leads to the integrated container.
