The innovative precision-volume-dispenser eco-PEN600, made by ViscoTec, offers a wide range of applications for low to medium-viscosity dispensing. Particularly suitable for dosing fat, colour, sealants, adhesives, oil, silicone, abrasive media and many other materials.

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.
