Mechanical seals with metal bellow

​​​ If the medium which has to be sealed is of high temperature, secondary seals may only be used restricted. For this kind of applications a unit with a welded metal bellow has proved its worth. For this design, profiled metal membranes are alternately welded with high precision on the inner- and outer diameter and consequently provide a leak-proof and spring elastic bellow unit for the seal ring.
