Abstract

The pump unit (1) especially for the delivery of a paste-form substance from a container (2) has a first coupling (3) for a pressure-tight connection to the container, and a second coupling (4) for connecting to a drive unit (5). The pump of the pump unit has a rotor connected to the drive, and the pump is connected pressure-tight to a pressure chamber which in its turn is connected pressure-tight to a connection (9) for a hose to transport the paste-form substance from the pressure chamber. An independent claim is included for a system for the making available of a paste-form substance, especially at building sites.
