Drainage presses of the PUEHLER E series work electro-hydraulically by means of different hydraulic cylinders. The material is fed through the curved feed hopper. The pressed out liquid or paste is collected in a collecting trough and can be drained by a separate pump. With presses from WEIMA, you can open filled disposable packaging in one operation, separate the contents and compress the packaging. For example PET packaging, beverage cans, spray cans, milk cartons and much more.
