2K Dispenser

preeflow-dispenser2k-header

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.

Precision mechanics coupled with the latest digital control – a combination designed to save you capital. Use it and you’ll soon find out.

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

  • eco-DUO450 and eco-DUO600
  • Self-sealing at approx. 2 bar with water as medium!
  • The self-sealing effect increases with the viscosity.
  • Dosing pressures to 40 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 %
  • Eco-DUO600: guaranteed safety shut down

eco-DUO600 with new safety feature: Through the newly integrated pressure sensor in the 2K mixing head with the combination of the flowscreen pressure evaluation a safety shut down of the system is guaranteed at any time.

    • Description

      The new 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!

Description

The innovative eco-CONTROL EC200-DUO, made by ViscoTec offers a wide range of applications for 2-K-precision-volume-dispensers.

Theory of function

The control unit eco-CONTROL EC200-DUO has been developed and tested for accurate work with the preeflow 2-K-precisionvolume-dispensers. The control unit has a variety of configuration options to dosing, dispensing time and mixing ratio. All production-related values can be stored and changed at any time. The operation takes place over an intuitive user guidance using a graphical user interface. An integrated pressure control ensures the optimum process safety of the system. There is also the possibility of data exchange with a USB interface.
