METAL BELLOW SEALS

In applications where the process temperature exceeds elastomer capabilities, metal bellows mechanical seals with graphite secondary seals are a good sealing option. Metal Bellows Single Seal is designed for high-temperature services typically found in chemical and petrochemical processes. Graphite secondary seals replace O-Rings to achieve the higher temperature requirements. Advanced bellows design distributes pressure uniformly across the span of the bellows plate to reduce stress and minimize weld fatigue. Component design replaces most OEM seals. Metal Bellow Seals are used for high-temperature applications such as Refinery, Petrochemical & Chemical industries. Due to its narrow seal cross-section design, it can replace the most types of seals used in ANSI pumps. Secondary seals are made up of Grafoil, which can withstand high temperatures up to 425°C.

We have the following Metal Bellow Seals

• MBR :- Rotating Bellow Assembly

• MBRC :- Rotating Bellow Single Cartridge Assembly

• MBRDC :- Rotating Bellow Double Cartridge Assembly

• MBS :- Stationary Bellow Assembly

• MBSC :- Stationary Bellow Single Cartridge Assembly

• MBSDC :- Stationary Bellow Double Cartridge Assembly

MBH Mechanical seal is a hook-sleeve design made for handling heat transfer media & high-temperature hydrocarbons. The seal is self-cleaning without springs.
