Coating Kitchen
During the coating and laminating process, the surface of the raw paper is coated with pigments (coating colour).
The coating kitchen is the main application for seepex progressive cavity pumps. This applies to the coating preparation as well as the feeding of coater in the coating system.
The coater is located inside or outside the paper machine. Its task consists of placing the coating colour onto the raw paper. This is carried out via a jet coater or a coating sump.
High quality coating colour is made up of pigments, adhesives and additives. Key pigments are calcium carbonate and kaoline. The adhesives are natural or synthetic. Additives are used, among other things, as brighteners or defoamers.
The seepex pumps are particularly well suited for pulsation sensitive processes due to their optimised geometries with a high metering accuracy. They meet the highest demands of the technically highly developed paper coating and laminating process thanks to the gentle handling as well as variable speeds and flow rates.
