adhesivesiliconefor high-viscosity media

DESCRIPTION The new precision-volume-dispenser eco-PEN330 made by ViscoTec offers a wide range of applications for low to high-viscosity dispensing. THEORY OF FUNCTION 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. APPLICATION On-the-dot dosage with maximum volumetric precision – dot-and-bead application with application speeds adaptable to track speeds – joint sealing technology. RANGE OF USES • Fats • Colours • Sealing compounds • Adhesives • Oils • Silicones • Abrasive media TECHNICAL FEATURES • Genuine volumetric dosing • Suck back effect • Viscosity-autonomous dosing • Easy to clean • Primary pressure-independent dosing • Controllable dosing flow • Pressure-tight without valve • Range of dosing pressures 16 - 20 bar
