sera Gruppe

We are an independent, family-owned company group headquartered in Immenhausen, right in the center of Germany. Since our founding in 1945 by Reinhold Seybert and Hubert Rahier, our name has stood for innovation, reliability, and flexibility. What started as a small operation has grown into one of the world's leading German companies in the field of dosing and hydrogen technology. We're proud to be a third-generation family business, currently led by Carsten Rahier, and we remain deeply committed to our roots while expanding our global footprint.

Our mission is to create added value for people and the environment through our technologies. We specialize in developing and manufacturing high-quality dosing pumps, dosing systems, and metal diaphragm compressors. These products are essential for a wide range of industries, including water and wastewater treatment, food and beverage production, breweries, and the chemical and petrochemical sectors. We are also passionate about the future of energy, which is why we have invested heavily in hydrogen technology, offering innovative solutions for hydrogen refueling stations and compressors to support the global energy transition.

We believe that our employees are the basis of our success. That's why we foster an employee-friendly environment with flat hierarchies and open doors, where success is celebrated together. With subsidiaries in the UK, Spain, South Africa, Austria, and Switzerland, and a network of partners in over 80 countries, we are truly an international team. We are dedicated to sustainable growth and providing efficient, custom-tailored solutions that meet the exact needs of our customers worldwide.
