Volumetric dosing dispenser eco-PEN300

for low-viscosity liquidsfor medium-viscosity mediafor high-viscosity products

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. Application: 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. Your advantages: - Genuine volumetric dosing - Suck back effect - Viscosity independent dosing - Easy to clean - Primary pressure-independent dosing - Controllable dosing flow - Pressure-tight no valve - Range of dosing pressures 16-20 bar - Preeflow guarantess 100 % bubble free dispensing due to an optimized deaeration - Compact size: length 216 mm, □ 29 x 29 mm, ø 33 mm
