For 165 years, the company Leybold, located at Cologne, Germany, has developed and supplied vacuum pumps, systems, standardized and customized vacuum solutions and after sales services for a wide range of industrial and research-based applications.

The foundation stone was laid in 1850: In this year, the company’s founder Ernst Leybold officially took over this enterprise as his own, paving the way for a comprehensive industrial use of vacuum technology. Even after selling the company again in 1970, his vision remained. One of the most important mile stones in the company’s history is the development of the molecular pump by physicist Prof. Dr. Wolfgang Gaede.

The name of the physicist is also relevant for another very successful pumping type, still being used in effective applications: for 100 years, the diffusion pump has been almost irreplaceable for many highvacuum processes.

With this principle, mixing of the jet and the gas to be evacuated is effected by diffusion of the gas into the jet stream. Modernization of diffusion pumps offer a high potential for energy saving, as in metallurgical applications of vacuum furnaces.

The success story of the oil sealed rotary vane pump started 80 years ago. These general purpose pumps are used in a high variety of vacuum technology applications and are proving their efficiency in industrial production as well as in research.

Not only Leybold Headquarters is celebrating an anniversary: Since 1990 the Dresden location of Oerlikon Leybold Vacuum is integrated into the high technology field of applications with innovative cryo technology.
