HERMETIC-Pumpen GmbH develops and manufactures hermetically sealed centrifugal pumps for demanding applications in the process industry. The product range includes canned motor pumps, magnetic coupling pumps, vacuum pumps, compressors, complete system installations, agitators and conventional centrifugal pumps. The pumps are designed for extreme temperatures, high pressures and the safe handling of aggressive, corrosive and hazardous fluids. Materials processed include steel, stainless steel, titanium, special alloys such as Hastelloy as well as grey and spheroidal cast iron. The pumps are used worldwide in chemical and petrochemical plants, refineries, power plants, the oil and gas industry, industrial refrigeration as well as in the fields of CCUS and wind energy. The headquarters with development and production is located in Gundelfingen near Freiburg; further subsidiaries exist, among others, in France, China, the USA and Singapore.
