Your Dispenser for Dosing Single-Component Fluids

preeflow® eco-PEN

A purely volumetric dosing system that applies the smallest amounts of single-component or 1-component fluids – for high-precision dosing technology. Thanks to the ViscoTec endless piston principle, low viscous to pasty liquids are conveyed perfectly. Independent of viscosity fluctuations, a clean, process-reliable dosage is achieved.

preeflow® stands for high-quality products, from control units to industrial dispensers. Always following our philosophy: “smaller, more precise, economical”. They are suitable for manual workstations as desktop devices or for automated operation. But also, as a built-in device in control cabinets or as front panel modules.
