Hermetically sealed pump technology from Gundelfingen
HERMETIC-Pumpen GmbH, headquartered in Gundelfingen near Freiburg, specialises in hermetically sealed centrifugal pumps. The portfolio includes canned motor pumps, magnetic driven pumps, vacuum pumps and systems as well as positive displacement pumps, compressors, complete systems and agitators. The pumps are designed for extreme temperatures, high pressures and the safe handling of aggressive, toxic or hazardous media and are used in chemicals, petrochemicals, the energy sector, oil and gas, industrial refrigeration as well as rail and maritime applications. Materials such as steel, stainless steel, titanium, Hastelloy, grey cast iron, spheroidal graphite cast iron and special alloys are processed. The headquarters in Gundelfingen is the centre for development, engineering and manufacturing; with around 750 employees worldwide, subsidiaries in Europe, the USA, China and Singapore and a global sales and service network, the company supports its customers throughout the entire life cycle of the pumps – from design through repairs and modernisation to spare parts supply and training.
