Metal Bellow Seal
Seal Type : MFI-MLT 701
The Series 701 are specially developed mechanical seal suitable for high temperature. The bellow is constructed by welding a series of diaphragms together at the edges. Each welded set of plates has a fixed axial movement along the shaft.
Type 701 having a grafoil, is used as a secondary member having excellent temperature range upto 400°C. It has an shrunk fit seal face which minimize face distortion. And in type 701 having ‘O’ ring due to change in its application. Bellow will eliminates the need of spring and provide flexibility to the seal.
