• Description 

The eco-DUO450 precision-volume dosing unit made by ViscoTec covers many applications within the low to medium-viscosity dispensing range.

  • Theory of function

The preeflow eco-DUO is a rotating, absolutely pressure-tight, positive displacement system with self-sealing rotor-stator arrangement. The controlled rotary motion of the rotor transfers the medium by displacement in the stator. The medium is unchanged by this process. And simply by switching to reverse-flow, preeflow ensures a clean and controlled stop of materia or medium. No drips, no mess!

  • Smallest dosing quantity: 0.010 ml
