Volumetric dispenser eco-DUO450

The preeflow precision volume dispenser eco-PEN 300, made by ViscoTec, is ideally suited for dosing tasks with low to high viscosity materials (e.g. dosing of adhesives, fluids or pastes). The proven ViscoTec endless piston principle, which is based on an progressive cavity pump, is a rotating, absolutely pressure-tight displacement system consisting of a self-sealing rotor and stator. Due to the controlled rotary movement of the rotor, delivery is generated by displacement of the medium in the stator. Pumping without changing the medium is guaranteed. As the material can also be conveyed backwards, preeflow® guarantees a clean, controlled material or medium break-off without dripping. Application: Whether dot dosing, with highest volumetric accuracy, most precise bead application with application speed adjustable to the application speed or in potting technology - preeflow means micro dosing in perfection.

The precision volume dosing unit eco-PEN450, made by ViscoTec, enables many applications in the low to medium viscosity dispensing range. It is ideal for dosing grease, paint, sealants, adhesives, oil, silicone, generally abrasive media and many other materials. The preeflow® eco-PEN is a rotating, absolutely pressure-tight displacement system consisting of a self-sealing rotor and stator. The controlled rotary movement of the rotor generates the flow by displacing the medium in the stator. Pumping without changing the medium is guaranteed. As the material can also be conveyed backwards, preeflow® guarantees a clean, controlled material or medium tear-off without dripping. Application: - point dosing, with highest volumetric accuracy - bead application with application speed adjustable to the web speed - Potting technology Your advantages: - True volumetric dosing - Retreat effect

The innovative precision-volume-dispenser eco-PEN700 made by ViscoTec offers a wide range of applications for low to medium-viscosity dispensing. preeflow® eco-PEN is a rotating and perfectly pressure-tight displacement system. Self-sealing rotor/stator design. Conveyance action by medium displacement in the stator through controlled rotor rotation. Safe conveyance without any modification of the medium. With its suck back option, preeflow® ensures clean and controlled material or medium cut-off while preventing post-dripping effects.
