For precision critical bead and repeatable mirco-shot/dot applications of one component viscous liquids and filled pastes. The new and innovative precision-volume-dispenser eco-pen 700 by Viscotec offers a wide range of applications for low to medium-viscosity dispensing.  Preeflow® eco-pen 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 rotation. 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.
On-the-dot dosage with maximum volumetric precision – dot-and-bead application with application speeds adaptable to track speeds – joint sealing technology.

(1) Max. dosing pressure and intrinsic tightness will decrease in direct proportion to a decrease in viscosity and increase in direct proportion to an increase in viscosity. Consultation with the manufacturer recommended.
(2) Volumetric dosing as absolute deviation in relation to one dispenser revolution. Depends on the viscosity of the dosing medium.
(3) Volume flow depends on viscosity and primary pressure.
