Dyeing with liquid can be a challenge. It all depends on reliable dosing, often with extremely low dosing quantities. The most important issues are changes in the viscosity of liquids and leak-proof use. Movacolor has developed a modular liquid dosing system with a universal motor unit, two types of pumps and several leak-proof packaging concepts. This offers you the possibility to assemble the optimal configuration
The peristaltic pump is used in processes with frequent color changes. Available as gravimetric and volumetric dosing system.
Advantages: - Easy color change - The gravimetric system provides a constant output - Low dosing rates - Easy to clean
Disadvantages: - Limited pump hose life - Limited pressure build-up - In volumetric mode, output depends on viscosity.
A gravimetric peristaltic pump is an ideal combination for color changes. Gravimetric control automatically compensates for the disadvantages of a peristaltic pump. The output of a peristaltic pump is highly dependent on the viscosity of the pump fluid, the type of pump tubing used, and the age/wear of the pump tubing.
For long runs, we recommend the use of a monopump. Available as gravimetric and volumetric dosing system .
Advantages: - Long life - Can build up pressure up to 10 bar - Performance independent of viscosity - Easy pump change - Extremely low dosing rates (gear pump) - High dosing rates (monopump).
Disadvantages: - The 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 a special nozzle adapter for easy installation and easy cleaning. MCLiquid: your total liquid dosing concept.
"We have tried several liquid systems, but this system is by far the best."
