Metal Bellow Seal Manufacturer
– Ensuring safe, leak-free operation of equipment under extreme conditions.
Sakowitz is dedicated to providing reliable sealing solutions for pumps, compressors, and reactors operating under high-temperature and corrosive conditions.
Structure and Function of Metal Bellow Seals
Metal bellows mechanical seals are high-performance sealing components used in pumps, compressors, reactors, and similar equipment. They replace traditional springs with metal bellows to achieve axial compensation and dynamic sealing without relying on rubber components, thereby offering superior high-temperature resistance and chemical corrosion resistance. This design effectively prevents liquid or gas leakage, making it particularly suitable for extreme conditions with temperatures up to 400°C and pressures as high as 60 bar.
Metal bellows seals are widely adopted in petrochemical, pharmaceutical, energy, and vacuum systems, serving as the preferred solution for high-reliability sealing applications.
Why Choose Metal Bellow Seals
Metal bellows seals demonstrate exceptional stability and sealing performance under high-temperature, high-pressure, and highly corrosive conditions. Their elastic-free design effectively avoids issues such as rubber aging, thermal decomposition, or chemical swelling, making them suitable for operating temperatures up to 400°C.
The bellows’ self-compensating properties absorb axial displacement and end-face wear, extending equipment lifespan and reducing maintenance costs. Additionally, the use of corrosion-resistant alloys such as Hastelloy®, Inconel®, and SS316 ensures outstanding sealing performance even in acidic, alkaline, and organic solvent environments. These seals are widely employed in continuous-operation equipment within the chemical, petrochemical, and energy industries, making them an ideal choice for high-reliability, zero-leakage systems.
