Schünemann has been successfully active for more than 80 years with technical competence and experience in the areas of special valves, filters and filtration systems. Their products have high quality requirements and are partially used under extreme conditions.

Featured items: Automatic Filters, Backwash Filters

The development, production and testing of  products are performed exclusively on SAB premises. This makes them independent from third parties and makes them able to react quickly at any time with technically challenging system solutions customized to the individual requirements of our customers. With SAB’s wide range of products, we can offer our customers a solution for almost every problem.

  • Special valves for marine and industrial applications up to 1000 bar
  • Manual and automatic filters for many different fluid applications
  • Materials according to customer specification
  • Freely selectable connections
  • Functional conversions and retrofits
  • Controls according to customer requirements
  • Spare part availability for several decades


Conventional machines are supplemented by the latest CNC turning, milling and drilling centers. The planning, controlling and monitoring of the complete production is computer-supported using the BDE data acquisition system and the connection to the ERP / PPS system. A particular plus is the final inspection of the products in many different areas.


Due to constant investments in our production and development and the special expertise of SAB employees, they provide their business partners not only with quality state-of-the-art products but also future-oriented innovations. Settings and functions are checked on five of their own testers, strength and leak tightness inspections as well as flow tests and pressure loss determinations are performed.  A top priority of SAB’s policy is to permanently expand the technical boundary conditions and parameters in order to respond at any time to the challenges of the market with optimal research and development options and to secure and expand our market position with outstanding quality products. Various patents from SAB  are impressive evidence of their commitment to research and development. One of these patents is a multifunctional valve specially designed for the filling of monogases and/or gas mixtures in a particularly compact modular design. This valve complies with the extreme guidelines and conditions of the Federal Agency for Material Research and Testing (BAM) concerning burnout safety in the case of oxygen surges and has obtained the approval for applications with an operating pressure of up to 400 bar.


It goes without saying that SAB engineers use all available PC-supported construction and design tools for the development and calculation of SAB valves. Thus, as well as the standard 3D CAD designs, the latest flow analysis and visualization tools such as Computational Fluid Dynamics (CFD) are also used. SAB environment is optimized by dimensioning and design programs and by our own solutions developed in-house.

Quality Assurance

The binding quality guarantee is an indispensable pillar of SAB philosophy. It is based on the constantly controlled combination of high quality materials and the strictest quality control for all production processes. This includes the comprehensive inspection of all valves and filters for strength and leak tightness as well as the continuous batch tracking of the materials used.  It also goes without saying that we are certified according to DIN EN ISO 9001:2008 and many more. Of course, Schünemann is a member of various national and international technical bodies and organizations.
