If you want to feed from 200 liter drums. In this case we recommend a press type S6-F with pressure generated by hydraulic unit, or pressure generated pneumo-hydraulically type S6-F/PH. The pressure plate moves into the drum and presses on the surface of the material. The material is fed through an outlet hole in the pressure plate through a connecting hose to the dosing unit. The maximum feed pressure for both versions is 12 bar.
