precision volume dosing unit


The eco-PEN330 precision volume dispenser made by ViscoTec enables many applications in the low to high viscosity dispensing range. 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. - True volumetric dosing - Retreat effect - Viscosity-independent dosing - Easy cleaning - dosing independent of inlet pressure - Adjustable dosing flow - Pressure-tight without valve - Dosing pressures from 16 to 20 bar
