STB GmbH has been working and testing more and more on hydrogen in the last few years. Many manufacturers have approached us for a reliable sealing solution in the field of mechanical seals and labyrinth seals. Intensive test work has led to far-reaching and safe solutions, which are already proving themselves in the field on a daily basis. We offer mechanical seals for hydrogen applications. These are mainly used in compressors (compressors and process gas compressors) or pumps. As a result, we have developed a product series for the use of a mechanical seal for hydrogen in a compressor or a mechanical seal for hydrogen in a pump. We call this series Hydroseal. Complex systems to operate these seals safely for hydrogen are developed, manufactured and tested in-house.


For each feasibility study we always need the framework parameters of the system. Speed, media temperature, pressures, barrier media etc. Contact us for your research projects or machines and we will check the use of our mechanical seal Hydroseal in your hydrogen application.
