The innovative 2K positive displacement pump eco-DUO450, made by ViscoTec, offers a wide range of applications for the two-component dispensing. Some possible application areas are electronic packaging, semiconductor, LCD/LED/OLED, photovoltaic, medical, biological chemistry, laboratory, optics and photonics, SMD/SMT and many more.

preeflow® eco-DUO is a rotating and perfectly pressure-tight displacement system (progressive cavity). 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.
