Device for pumping viscous materials

摘要

The pumping device is esp. adapted to handle viscous material such as mortar, primer, plaster or paint. It comprises a material container (12) and a pump (28) with a connecting piece (48) at the outlet of the pump pressure chamber (30). An additional connection (38) is located at the pump outlet, which is connected with the material vessel and holds the pressure chamber (30) to the container outlet (25) via a least one tensioning element (40).
