The rolary metal bellows mechanical seal can replace the sprnng echanical seal under low and medum pressure. The redai imensionismore compact. The tllowing performance is good it may be used tor the highviscosity medium. The functond of metal bllows is to seal, transmit torque and offer the forca.NO foating secondary ring is needed; therefore the folowing performance is very good and it has a strong an-interferenca ablity. The rotary bellows can prevent particles from going into its sheets, which can realize self-cleaning. The stationary ring is fioating type. The seal performance is stable and relable. The welding edge is designed into a special angle to minimze welding stress. A wide selection of parts materal can be usee for dterent serice conditions.
Compact type of ZMB1, standard modular design, generaly used as the aturesentnospnenc side sealfor a dual seal in high temperature services.
