We are DrM

DrM, Dr. Mueller AG was founded in 1982 by Dr. Hans Mueller (1913-1984), a graduate of the Swiss Federal Institute of Technology in Zurich. It is the legacy of this brilliant industrial entrepreneur and creative inventor, whose influence lives on in the chemical process industry. His boundless ingenuity was reflected in more than four hundred inventions for which patents were granted during his academic and industrial career. Several of these revolutionized chemical processes in numerous countries.
DrM is still privately owned and managed by highly skilled technical and creative professionals. Our primary goal is to find and develop solid-liquid separation solutions that help us live in a cleaner environment while creating significant financial benefits for our customers. The fully closed system design, automation, washing and drying operations of our filtration systems have a significant impact on achieving these goals.
DrM is a global company headquartered in Switzerland with subsidiaries in the USA, Poland, China, India and Malaysia. It is represented worldwide by commercial agencies, licensees, representatives and its own sales offices. Further information can be found in the Contacts section. The FUNDABAC® and CONTIBAC® cartridge filters are widely used throughout the processing industry. All DrM filters and mixers are made to measure to suit the specific process. Solutions are often developed on an individual basis.

The history of the Lehmann company starts in June 1945 when a repair business and workshop was founded in Hammer, near to Pöhl, by Heinz Lehmann. The most straightforward means were used for manufacturing and repairing metal goods for everyday use. The product range was extended for Carl Zeiss Jena, developing a new segment with clamping equipment for the optical industry and even building drives for the domes of observatories.
Construction of the Pöhl dam in 1958 made it necessary to relocate. Nearby Jocketa was selected deliberately because many of the employees from Pöhl also moved there. The Lehmann family also wanted to remain in the heart of the Vogtland region.
In 1972, the new generation of the family entered the business with Thilo Lehmann. Shortly after that, "VEB Carl Zeiss" took a share in the company as a partner, resulting in partial nationalisation. In 1975, Heinz Lehmann was accused of preferring West Germany companies, and imprisoned for 9 months. Gradually, all the "Lehmanns" were prised out of the company. Only in 1977 was the founder of the company completely rehabilitated.
In the course of the reunification of Germany, Heinz and Thilo Lehmann were then able to reprivatize the company on 16 June 1990.
At the end of the 1990s, Markus and Titus Lehmann joined the company as the 3rd generation of the family to join the metal-processing industry. Markus Lehmann became the head of production in his family's company, Titus Lehmann founded his own company and began to manufacture and sell stainless steel grilles.
Over the course of the years, Titus Lehmann developed his company's portfolio - Lehmann-UMT GmbH - on a continuous basis, first by adding activities in sheet metal processing, followed by filter and conveyor technology products. Additional aspects of the company profile today include engineering, 3-D design and special machine construction.
The change to the Renewable Energies Act (EEG) in 2014 caused Thilo Lehmann's Lehmann Maschinenbau GmbH serious financial problems. Consequently, Titus Lehmann decided to buy the production facility in Jocketa, meaning that environmental technology also supplemented the product range of Lehmann-UMT.
Since the end of 2014, the company has been operated with a streamlined structure and the 80 employees from two plants have grown together into a strong team.
