Otto Siemen

Otto Siemen (born November 1, 1881 in St. Margarethen (Holstein) ; † June 29, 1966 in Itzehoe ) was a German engineer, inventor and manufacturer.

Life

Otto Siemen studied from 1900 to 1904 in Cöthen (today: Köthen ) at what was then the Higher Technical Institute, which later became the State University for Applied Technology (Friedrichs-Polytechnikum), general mechanical engineering, with a final exam in 1904. At the beginning of his studies he joined the Marchia, the later Corps Marchia Braunschweig.

In 1907 he started working for Siemens-Schuckert-Werke in Berlin-Siemensstadt , where he worked in the pump test field. It was there that he met his future business partner Johannes Hinsch , who started his work there in 1908. During the First World War he took over the development and expansion of self-priming air pumps for the Imperial Navy at Siemens-Schuckert-Werke based on patents he had registered .

After the war, he and Johannes Hinsch founded Siemen & Hinsch mbH, SIHI in St. Margarethen in 1920 . It was moved to Itzehoe in 1925 . The first foreign representation in Austria was established as early as 1922 .

With their innovative ideas Otto Siemen and Johannes Hinsch led the company into the global top group of manufacturers in the fields of self-priming liquid pumps and vacuum pumps that convey liquids . As "Sterling SIHI GmbH" it now belongs to the internationally operating Sterling Fluid Systems group.

Otto Siemen was awarded the golden Rudolf Diesel medal in 1963 for his services to the development of self-priming centrifugal pumps .

Services

Together with his partner Johannes Hinsch, Otto Siemen invented the principle of the self-priming side channel pump for pumping liquids and gases in 1920 .

This type of pump is used today in chemistry, pharmacy, the energy industry, water management, the food and beverage industry, the plastics industry, the steel industry, the paper industry and for general plant engineering. In particular, the ability of the side channel pumps to convey a high amount of gas and the self-priming ability of the side channel pumps ensure a high level of process reliability in a wide variety of process engineering cycles. The importance of this type of pump can be seen in the fact that since 1920, SIHI has sold more than 2 million side channel pumps for a wide variety of applications.
