Dispenser 3RD4-EC / Progressive cavity pump

In order to avoid chemical reactions such as curing or crystallization during the dosing process, any contact with metal in the area in contact with the material in the dispenser was avoided. The materials used have been carefully selected: On the one hand with regard to chemical resistance to adhesives and other fluids and on the other hand with regard to highest resistance to physical wear by abrasive media. Highly reactive materials such as sulfuric acid, anaerobic UV curing acrylates and electrolytes require special treatment. They can be dosed with highest accuracy and best repeatability. The new metal-free dispenser can be easily installed on existing ViscoTec drive technologies and offers the same advantages as other proven dispensers from the portfolio of the dosing technology specialist. The metal-free dispenser is available in many sizes.

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

Examples of materials for dosing: 1- and 2-component epoxy, UV / light-curing / thermosetting adhesives, highly filled materials, anaerobic adhesives, shear-sensitive adhesives, heat-conducting paste, sealants, flavourings, silver conductive paste, flux, perfume, isopropanol, industrial oils, silicone, alcohol, grease, paint and ink, MEK, braze paste, PU, acetone, petrol and many others. The preeflow® eco-DUO 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

ViscoTec Dispenser 3VMP22 as a volumetric dosing pump for larger volumes ensures an even and reliable product supply of viscous, structure-sensitive and solids-laden products - with a repeatability of +/- 1 %! Absolutely precise, uniform and reliable dosing of various media and handling of larger volumes. Alternating opening chambers ensure gentle product transport and pulsation-free output. Your advantages: - no dripping or thread pulling due to programmable retraction - direct linearity between spread rate and speed - constant dosing volume even with fluctuations in density, viscosity and temperature - reliable dosing without heating the medium - drive with servo or three-phase motor - easy programming of quantity and speed - low maintenance, quick disassembly - free inlet possible, as self-priming mode of operation
