EagleBurgmann is proud to report that the first high-pressure paddle dryers went into operation in 2006 at a silica production plant.
The machines were completely redesigned to withstand the high operating pressure (up to 20 bar). The solution, developed by a German manufacturer, was a pioneering achievement. The sophisticated shaft seal was developed in close collaboration with Burgmann Industries.
Mechanical seals are used as shaft seals in pumps, agitators, compressors and other rotary machines handling liquid and gaseous media. The process pressures which have to be contained by the seals range from vacuum to more than 400 bar. In some cases, the chemical and thermal stability required of the mechanical seal is very high. The design of the seal and the choice of material from which it is made play a crucial role in making sure that it operates reliably for a sustained length of time under the conditions for which it was designed and for which the material was chosen.
