WD-Liquid

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

PUMP DOSAGE for liquids WD-SYSTEM – COLORING ON THE INJECTION OR EXTRUSION MACHINEFor 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

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.
