Germany LEYBOLD Leybold Vacuum Pump vacuum technology as an international market leader, Leybold company has experienced 150-year history. The beginning of creation, Ernst Leybold Company (1827 - 1907) is mainly engaged in the business of wine and a variety of pharmaceutical appliances (including glass bottles, cream cans, thermometers and scales), with the price of customer satisfaction and business promotion activities, the company evolved growth. In 1854, the company expanded its business scope to physical, pharmaceutical and chemical instrumentation field. To meet the growing market demand, the company established its own base and glass-blowing machine shop in 1867, the official start of production for physical science and laboratory equipment. Since 1906 renamed, professor of physics at Leybold start and Technology (located Karsuhe) Wolfgang Gaede (1878-1945) had a highly successful collaboration. The company's management and Alfred Schmitt cooperation until 1931, then in charge of the company management, Dr. Manfred Dunkel until 1967. The successful cooperation are two main innovations: molecular air pump (1911) and the diffusion pump (1913). Thus the invention also demonstrates the ability of the superior product of early-stage companies has, so far these innovations have enjoyed the honor in the history of vacuum technology. Early 1930s, Leybold mark for the first time to produce, as a symbol of well-known companies Leybold, has been used up to 1967, closely linked with the Leybold company name. Metallgesellschaft AG and Degussa AG. E.Leybold Nachfolger companies were acquired shares in 1948 and 1955. The early 1960s, the company introduced a number of newly developed products to market, including liquid helium cryogenic pumps and helium leak detectors (1962) and the first sputter ion pump (1963) series. Through years of close and fruitful cooperation, in 1967 and located Habau E.Leybold Nachfolger of WCHeraeus Co. eventual merger. The new company was named Leybold-Heraeus Ltd., Degussa, Metallgesellschaft and WCHeraeus three parties holding equal shares. Leybold Vacuum is one of the largest equipment suppliers in the world. Currently, four countries in the world, with factories, each plant producing different line of vacuum their component parts. They are located in: - Cologne, Germany, the company's headquarters. Almost produce all product lines. - The United States, Pennsylvania, specializes in the production of dry pumps used in the semiconductor industry, cryogenic pumps. - French tile Lang Adams, specializing in the production SOGEVAC series single-stage rotary vane pump. - Tianjin, China, specializes in the production TRIVAC C series two-stage rotary vane pump.
