WD Liquid

Pump dispenser for liquids

Dosing of liquids on the plastic machine in its periphery with the WD system
The WD system is suitable for high-precision micro-dosing on the injection molding machine and also for assembly on the extrusion machine

WD-Liquid WD-Liquid PUMP DOSAGE for liquids
WD-SYSTEM – COLORING ON THE INJECTION OR EXTRUSION MACHINE
For liquid additives

The devices of the WD series are high-precision dosing devices for assembly on the injection molding or estrusion machine.
Upon a shot signal from the spraying machine, the liquid additive (in most cases color) is metered into the main component to be freed.

The device works with peristaltic dosage

  •     Suitable for micro-injection molding
  •     Highly accurate by stepping motor with step monitoring
  •     State-of-the-art electronics and control
  •     Designed for 24 hours operation
  •     Material feeding directly on the intake of the spraying machine


ADVANTAGES

  •     Accurate volumetric dosing by stepping motors
  •     Constant metering
  •     Simple color changes
  •     Perestaltic pumphead
  •     Product-contacting parts optionally available in stainless steel (1.4301)
  •     Monitoring the dosed motor steps
  •     Large dosing range due to variable speed
  •     User-friendly color touch panel display
  •     Logbook function
  •     Export of data to a USB stick for external evaluation


BASIC EQUIPMENT

  •     Material chart: Variable
  •     Material: aluminum or stainless steel
  •     Electrical Connection: 230V/50Hz
  •     Product-contacting stainless steel (optional)


DOSING RANGE

  •     Motor speed 1% – approx. 0.01 gr / s*
  •     Motor speed 60% – approx. 1.50 gr / s*
* Depending on fluid material

The dosage on or at the machines gives the processors the flexibility they need to produce economically.
Option: WD system for powder and granulate
