About us

STA has been manufacturing and marketing centrifugal separators and complex systems for clarifying industrial fluids since 1992. Thanks to many decades of experience in different fabrication processes, such as grinding technology and surface treatment, as well as our know-how in filter technology, we have been able to gain the confidence of many renowned customers.

Our core competence engineering results from the know-how of more than 3,000 successfully implemented projects and separators worldwide. Considering always the latest safety regulations we develop high-performance, long-life and safe machines.

By means of research on our machines’ fluid dynamics and extensive field trials we make sure that STA’s separators remain the best performing on the market. We are keeping our high quality standards by adding value in our 800 m² production site following certified processes like ISO 9001 and WGH 19 L (German Water Protection Act).

Today, 55 employees are working in the company-owned factory, which was built in 1993 and considerably extended in 2000, and again in 2017.


Our success is based on not just building systems, but on providing solutions for our customer’s complex tasks. The basis for this is, on the one hand, a profound understanding of the filter and centrifugal technology used, but on the other hand, and much more decisively, familiarity of the process at the individual customer where the clarification system is to be installed.
