The innovative preeflow precision-volume-dispenser eco-PEN300 made by ViscoTec offers a wide range of applications for low to high-viscosity dispensing (for example dispensing of adhesives, fluids or pastes).
The built-in, reliable ViscoTec endless piston principle which is based on a progressive cavity pump, is a rotating and perfectly pressure-tight displacement system - with a self-sealing rotor/stator design. Conveyance action by medium displacement in the stator through controlled rotor movement. 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.
Whether on-the-dot dosage with maximum volumetric precision or dot-and-bead application with application speeds adaptable to track speeds or joint sealing technology - preeflow means micro dispensing in perfection. In the area of electronics, packaging, LCD/LED, optics and photonics, in the medical technology, biological chemistry or many others.
