Dyes & pigments

Outstanding purity

Dyes and pigments have a wide range of applications. For example, high-quality dyes and pigments are used in the pharmaceutical and cosmetics industries. The production of these materials requires efficient filter systems for essential process steps such as filtration, washing and pre-drying. Our rotary pressure filters (type RPF) or indexing belt filters (type BF) cover these requirements efficiently. Our Autopress (type AP) is also used for special applications such as products or intermediate dye products that are extremely difficult to process. Typically, a thin cake and a high level of purity are required, and our systems easily meet these requirements thanks to a variety of cake treatment options.
