1K Dispenser

preeflow-dispenser1k-header

Our dispensers and benchtop dispenser consist of drive and dispenser unit and are supplied to you with the stator, which is easy to assemble. The preeflow® eco-PEN 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 material or medium. No drips, no mess!

The preeflow® eco-PEN await you with many features:

  • Self-sealing at approx. 2 bar with water as medium!
  • The self-sealing effect increases with the viscosity.
  • Dosing pressures of 16 to 20 bar are possible.
  • This permits smaller needle and nozzle cross-sections.
  • A basic suction pressure can be applied (for high-viscosity media).
  • The pressure tank is not required with self.levelling fluids.
  • Accuracy of dosing ± 1 %
  • Repeat accuracy > 99 %

  • Description

    The innovative precision volume dosimeter eco-PEN 300 made by ViscoTec offers a wide range of applications for low to high-viscosity dispensing.

    Theory of function

    preeflow® eco-PEN300 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.
