Our company would like to invite you to get to know STB GmbH better. According to our name, we stand for customer service and technical advice. As a still young company, we stand for constant development and expansion of all areas such as production, trade and service.

STB GmbH produces mechanical seals and special seals for pumps, compressors, blowers, compressors and turbines, among others. Furthermore, sliding surfaces for mechanical seals are manufactured in our company. Materials made of carbon and chromium oxide are mainly used. Of course, we also process tungsten and silicon carbide.

In recent years, our company has developed references for mechanical seals from 12 mm to 650 mm shaft diameter. Today, we also produce quickly available and proven sealing solutions for end customers through our standard cartridge seals, single-acting ecoSiron™ and double-acting proSiron™ mechanical seals.

A great deal of attention is paid to the repair service of technical equipment. Mainly mechanical seals, pumps, gearboxes, motors, agitators and blowers are overhauled. In doing so, we can fall back on a large machine park. With our well-trained staff, the plants can be overhauled at your site, but also in our company. All plants are checked before delivery and equipped with the appropriate documents. Thus, the processes are traceable even after years. As part of our training program, our employees are SCC certified, among other things. Furthermore, together with our partners, we can supply new mechanical seals, bearing seals, pumps, gearboxes, motors, agitators and much more. This is always coordinated with our technical field service. We cordially invite you to get to know our company even better on the following pages.
