eco-PEN450

The ViscoTec eco-PEN450 dispensing system is a rotating and perfectly pressure-tight displacement system ideally suited for dispensing precise volumes of low- to medium-viscosity materials. This dispensing pen has a self-sealing, rotor/stator design. Conveyance is by medium displacement in the stator through tightly controlled rotor rotation, assuring accurate dispensing without any changes to the dispense material. The progressive cavity mechanism exhibits minimal shear stress upon the medium compared to alternative positive displacement platforms such as gear pumps, auger pumps, and rod driven metering systems. In addition, the suck-back feature of the eco-PEN450 ensures clean and controlled material or medium cut-off, while preventing post-dripping. It offers maximum volumetric precision for both dot and bead applications. Application speeds are adaptable to track speeds provide precise joint sealing.

Suitable to dispense low to medium viscosity materials including UV light-curable adhesives, greases, inks, medical fluids. Typical applications include microdots, dots, beads, and potting.
