Description
The new and innovative 2-K-precision-volume-dispenser eco-DUO 450 made by
ViscoTec offers a wide range of applications for the 2-component dispensing.
Functional theory
preeflow® eco-DUO 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 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
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
• electronic packaging • semiconductor • LCD/LED/OLED
• photovoltaic • medica • biological chemistry
• laboratory • optics and photonics • SMD/SMT
Technical Features
• 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 up to 40 bar
