Cream-fat-powder with 70 % fat content, adhesive and compacting iron oxide, wet charcoal – there are many examples of highly adhesive and sticky powders and other materials. For proper and reliable material transport, surfaces with product contact can be coated with different specific materials. To avoid cross contamination and reduce residual material inside the conveying system, the parameters of the conveying process and the surfaces can be modified and optimized according to the specific needs.
Special coatings (e.g. Halar®) are used with corrosive materials and conveying environments to protect all parts of the vacuum conveyor.
If the vacuum conveyor itself is installed inside an aggressive atmosphere or comes in contact with aggressive media, the outside of the conveyor will be coated, too. Additionally, MULTIJECTOR Vacuum Pumps are available in various materials (various stainless steel and/or plastic materials) and can be supplied acid-proof.
Certain industries have very strict material requirements, e.g. all equipment must be completely free of copper. As Volkmann manufactures most of its systems in-house, products and solutions with alternative materials can be supplied quite easily.
