Products Information

2-component screw pump eco-DUO 450

The ECO-DUO450 is a 2-component constant-flow volumetric discharging device, newly developed by ViscoTec. It is suitable for discharging a very small quantity of liquid of low to medium viscosity, covering a wide range of applications.

    • Two components mixed: Minimum discharge rate = 0.01 ml, Flow rate = 0.2 - 12 ml/min.
      Micro-dot and thin-line applications are possible while two components are mixed and discharged.
    • High accuracy discharging can be repeated even in the event of changes in viscosity and/or medium feeding pressure.
  • Suck back by reverse rotation of the rotor ensures neat cut-off and prevents dripping of liquid material after discharging.
  • Discharging volume can be easily adjusted using a special controller.
  • Simple structure and easy maintenance

*1 The maximum discharging pressure and intrinsic airtightness increase and decrease in proportion to viscosity. See the manufacturer's recommended values.
*2 Volumetric discharge as the absolute deviation against dispenser rotation. It depends on the viscosity of the medium to discharge.
*3 The volume flow depends on the viscosity and initial pressure.
*4 Depending on the type of static mixer.
