SKU: 029 Category:


A metal bellow type seal suitable for very high or very low temperatures and other applications where elastomer or PTFE gaskets could cause problems.
NB: To ensure the flatness of the lapped stationary ring, particular care must be taken with the locking screws on the gland plate. The number of screws is dependent on the seal size and cannot be less than : 4 till Ø20, 6 till Ø 28, 8 till Ø 60 and 12 till Ø 75. Also the screws must be tightened evenly to avoid distortion of the stationary ring. The cooling circuits shown in the two drawings must be used according to the requirements of the application.
