Expansion joints are flexible connections installed in piping and ducting systems to accommodate thermal expansion and/or vibration caused by changes in temperature, pressure, media and more. With more than 45 years of experience, KE-Burgmann-EJS is one of the most experienced and innovative expansion joint manufacturers worldwide. As a Freudenberg company, KE-Burgmann-EJS handles the design, manufacture, technical support and service of its metal expansion product line. Bellows DesignA key feature and basic element of these expansion joints is the bellows. The design of the bellows is predominately determined by movement, pressure, temperature, service life, materials and corrosion. Bellows are manufactured by forming corrugations, or convolutions, in thin-walled metal cylinders. |
These cylinders can then be inserted inside each other to form multi-ply bellows. All bellows are formed in their cold state, with optional heat treatment performed afterwards if applicable. The bellows, like those found in the EagleBurgmann MBS682 seals, provide flexibility of movement and are designed to absorb axial compression (up to 50%), lateral offset (±20%) and angular movement. TestingWelding integrity and product quality can be verified with various non-destructive tests and are carried out in-house or externally with supervision. Tests include:

The manufacturing of chemical and pharmaceutical products puts considerable strain on the sealing technology utilized. Optimum quality, a worldwide service network and decades of experience in application engineering make EagleBurgmann a leading manufacturer of sealing systems in these industries.
In addition to meeting stringent technical requirements, a seal has to adhere to many other regulations in connection with cleanliness, health and government legislation. EagleBurgmann mechanical seals have been used successfully worldwide in sterile processes for over 20 years.
The cutter heads on quarrying and mining machining are fed with water, not only for cooling purposes but also for settling the dust and extinguishing any sparks produced by the cutting tools. EagleBurgmann mechanical seals perform the dual function of rotary joint and seal for the cutter and roller heads.
EagleBurgmann sealing systems feature maximum operational reliability, convenient maintenance and low leakage rates with necessary environmental protective measures.
EagleBurgmann sealing systems feature maximum operational reliability, convenient maintenance and low leakage rates with necessary environmental protective measures.
Modern sealing technology makes a major contribution to optimized production processes and its further development. A large number of major international suppliers of machinery to the paper industry trust in EagleBurgmann seals.
With automations in marine applications and the protection of our seas, sealing technology is becoming increasingly important. EagleBurgmann seals meet these high economical and ecological demands and have been certified and authorized by many shipping institutions.
The building industry makes intensive use of submersible pumps because of their mobility. Thanks to their liquid-tight and pressure-proof design they are equally popular in waste water systems. EagleBurgmann elastomer bellows seals are a reliable and proven shaft seal solution for submersible motors in pumps, aerators, agitators, etc.
