    • Safe and clean handling of liquid chemicals

Volumetric Dispense Unit

The Volumetric Dispense Unit (VDU) has been designed to volumetrically dispense chemicals for dyeing and finishing applications.

The VDU is ideal for large batches that require a fast preparation such as thickeners and batches for pre-treatment, dyeing and/or finishing.


The combination of constant flow, fastswitching valves and accurate flowmeters results in a highly accurate and very fast dispense.


The VDU rapidly dispenses all your liquid chemicals with an accuracy of +/- 0.5 flow-pulse or +/- 0.3% of the required volume. The maximum viscosity is  300 cP.


Dispensing and dissolving takes place in a controlled environment, assuring reproducible results, batch after batch.

Easy operation

The Vanwyk software on an industrial PC allows for an easy operation. The user-defined process takes place automatically, no operator intervention is required: just choose the recipe and the required quantity.


The unit can be integrated into a fully automatic dyehouse, combining chemical dye dispensing and distribution to the dye machines.


The VDU saves labour costs and chemical consumption.


Ready batches will be pumped directly to the finishing machine upon request by its operator. This system may use Vanwyk’s special 3-way valves.


The valves and pipes are constructed in stainless steel. The pump is a self-priming heavy duty displacement pump.

Safe and Clean

The VDU reduces water pollution:

  • Rinsing is part of the recipe.
  • No useless draining of batches because of preparation errors.
  • No over-production: additional amounts can be prepared quickly and reproducible.
