Mechanical metal bellow seals
Mechanical seals in the Metal bellow series have a universal field of application. They are designed for extreme ranges of tempera- ture and for high-viscosity media. There is no dynamic O-ring and therefore a bel-lows seal will never hang-up.
Used in all types of rotating equipment,pumps,To suit industries.
Such as sgeneral chemical,oil refining,petrochemical,pharmaceutical,
pulp and paper,and waste water treatment.
oil,water,and other middle corrosion medium
