Dyes are used to color the end product and are often dosed as color intensive fluids with relatively low flows. They are for example used in the paper industry, for producing detergents, as well as in the pharmaceutical and food industry.
High quality coloring
Dosing dyes in a continuous environment requires constant and pulsation-free dosing in order to homogenize the color in the end product, which is an absolute necessity for high quality coloring.
Gear pumps and dosing systems
The use of gear pumps allows for pulsation-free dosing. In combination with a dedicated flow measurement system, dyes can be dosed with accuracies of « 0.3%. Color dosing systems offer the benefit of using the minimal volume of dye which helps to reduce production costs.
For this purpose, Suurmond has supplied various pump types from HNP-M, Gather, Maag and MAHR as well as complete dedicated dosing units. The dosing units can be plug & play supplied with dosing accuracies of 0.3% or better.
