The core competences of SEEFRIED Verfahrenstechnik GmbH, based in Weyhe near Bremen, Germany, include process engineering systems connected with the production of pharmaceutical and cosmetic products. From the actual homogenizing mixers and agitators, the dosing and weighing by means of our dosing station, through to the processing facilities in the environment and their optimal operation, we are there for you with our comprehensive range of services, from the planning to construction supervision of the processing facilities and process optimization. More than 100 customers in 20 countries already rely on our experience.
For us, real values such as reliability combined with the highest performance of the solutions developed have “priority”. We therefore attach particular importance to high-quality and technically advanced process technology, the functionality and quality of which we ourselves are convinced. Customer value and customer satisfaction are of paramount importance to us..
… are high – just like those of our customers in the pharmaceutical and cosmetics industries. Whether services, plants or spare parts: we design highly stressed and moving parts more generously than required and expect the same from our suppliers. This ensures a long service life, lasting value and consistent product quality. It is no coincidence that many of our customers come from the most strictly regulated industries – and we are proud of that.
Reliable service
Our service does not end with commissioning. We are just as happy to answer questions from ongoing operations as during the planning phase, and we support you when requirements or conditions change. For our dosing station we provide support throughout its entire service life – we supply spare parts even years after purchase.
New processing methods or improvements to previous processes are being sought for around 14,000 existing raw materials.André Seefried
Customized solutions

We develop the right solution for you.
The company
SEEFRIED Verfahrenstechnik GmbH was founded in 2013 by André Seefried. From 2010 to 2014 he was a member of the board of Vakumix Rühr- und Homogenisiertechnik AG, which his father Erwin Seefried had founded in 1995 – read more in our history. In 2014 the business of Vakumix Rühr- und Homogenisiertechnik AG was sold to NETZSCH Vakumix GmbH. There is no corporate or economic connection with NETZSCH Vakumix GmbH. As of 31 December 2024, the equity of SEEFRIED Verfahrenstechnik GmbH exceeds EUR 1 million – a solid basis for long-term projects and supply relationships.
With our expertise in mechanical and process engineering, we advise customers from the pharmaceutical and cosmetics industries – from brief technical information to multi-year projects, from building planning to the commissioning of complete production plants. Careful planning saves time and money; as a small company we respond flexibly and quickly.
The roots of SEEFRIED Verfahrenstechnik GmbH go back a long way: Erwin Seefried, design engineer and father of company founder André Seefried, has been named as inventor in numerous patents on agitators, scrapers and homogenisers since 1978 – first at A. Berents GmbH & Co. KG (Becomix) in Stuhr, in which he held a 30 % limited partnership share from 1978 to 1993, and from 1995 as founder and CEO of Vakumix Rühr- und Homogenisiertechnik AG in Weyhe. The patents show that he played a key role in developing the homogeniser technology of both manufacturers. This know-how flows into our consulting, service and spare parts today.
