Bellow Seals

bellows manufacturers in India

As trusted metal bellows manufacturers in India, Sam Seals India supports custom requirements such as size, pressure rating, temperature range, rotation speed, and media compatibility. Share your pump details, operating conditions, and application type—our team will recommend a suitable metal bellow seal solution for dependable results.

When your equipment runs under high temperature, pressure, or corrosive media, a Metal Bellow Seal becomes a reliable choice for long, leak-free performance. It is commonly used in pumps, mixers, reactors, compressors, and other rotating equipment where standard elastomer seals may fail. The metal bellows design works as both a spring and a dynamic seal element, helping maintain stable face contact even during shaft movement, vibration, and thermal expansion.

At Sam Seals India, we focus on delivering consistent sealing performance with precision-engineered designs that support tough industrial applications like chemicals, pharmaceuticals, refineries, power plants, and water treatment. Our seals are designed to reduce unplanned shutdowns, control leakage, and improve the life of bearings and shafts—so your operations stay efficient and safe.

A metal bellows seal is also a smart option for services involving hot water, steam, hydrocarbons, solvents, acids, and other aggressive fluids (depending on material selection). With the right seal selection and installation, you can achieve lower maintenance costs and smoother plant operations.

TYPE SSI-16 : is Inherently unbalanced metal bellow seal. This seals are independent of direction of rotation. The unique feature of this type of seal is that, there is no dynamic ‘O’ rings and therefore it will never hangup or damage the shaft and sleeve, it also has an ability to handle corrosive as well as abrasive & viscous media. These seals have self-cleaning & non-clogging construction. With selection of special bellow material it can be used in highly corrosive media.
