Coloring with liquid can be a challenging operation. It all depends on reliable dosing, often at extreme low dosage rates. Variation in viscosity of liquids and spill-free handling are the main issues. Movacolor has developed a modular liquid dosing system with one universal motor unit, two pump types and several spill-free packaging concepts. This offers you the possibility of composing your optimum configuration.
Peristaltic pump
The peristaltic pump is used in processes with frequent color change. Available as gravimetric and volumetric dosing system.
Advantages: – Easy color change – The gravimetric system provides a constant output – Low dosing ratesEasy to clean
Disadvantages: – Limited life time of pump hose – Limited pressure build-up – In volumetric mode the output depends on viscosity
A gravimetric peristaltic pump is an ideal combination for color changes. The gravimetric control automatically compensates for the disadvantages of a peristaltic pump. The output of a peristaltic pump is heavily depending on the viscosity of the liquid, the type of pump hose used and the age/ wear of the pump hose.
Mono pump/gear pump
In case of long runs we advise to use a mono pump. Available as gravimetric & volumetric dosing system.
Advantages: – Long life time – Can build pressure up to 10 bar – Output independent of viscosity – Easy change of pumps – Extreme low dosing rates (gear pump) – High dosing rates (mono pump)
Disadvantages: – System should never run dry – Difficult to clean
Both systems are also available in a volumetric configuration.
To complete the package we supply inline mixers and special nozzle adapters for easy installation and easy cleaning. MCLiquid: your total liquid dosing concept.
“We tried several liquid systems but this system is by far the best”
This unit is part of the Movacolor modular dosing concept and can easily be integrated and/or combined with all other products of the Movacolor product range.
