In sectors such as those that operate in extreme temperatures, under extreme pressure, and with high levels of aggressive chemicals, conventional sealing solutions simply cannot be relied upon to provide long-term performance. To address these challenges, industries need to adopt advanced sealing technology that ensures consistent performance across the most challenging operating conditions. Arohan Seals is one of the trusted Metal Bellows Mechanical Seal Manufacturers in St. Petersburg who is able to offer precision-engineered sealing solutions which are specially designed for critical industrial applications which demand a high level of thermal stability, leak-proof performance and long service life.
High-performance metal bellows mechanical seals are built with advanced engineering practices, precision-formed metallic bellows assemblies and superior-grade metallurgy for smooth sealing in extreme operating conditions. These seals are engineered for high-temperature and high-pressure applications, offering superb resistance to thermal expansion, corrosion, shaft wear and chemical attack while guaranteeing reliable performance and efficiency.
Unlike conventional mechanical seals that use dynamic elastomers and exposed springs, metal bellows mechanical seals utilise flexible metallic bellows that function both as the spring mechanism and secondary sealing element. This high-end non-pusher design minimises elastomer hang-up concerns, reduces risk of damage to the shaft and ensures even loading of faces for seamless and consistent sealing performance.
We produce various sealing types such as edge-welded metal bellows mechanical seals, formed metal bellows seals, rotating metal bellows mechanical seals, stationary metal bellows seals, and high-temperature metal bellows seals for pumps, compressors, reactors, mixers, steam systems and rotating equipment under severe industrial conditions.
Sealing solutions are used in industries like oil refineries, petrochemical plants, pharmaceutical manufacturing, chemical processing units, thermal fluid systems, power generation plants, and cryogenic industries for their excellent durability and reliable sealing performance.
With a team of experienced engineers, we specialise in precision manufacturing, rigorous quality control, and providing tailored sealing solutions for industries that demand reliable performance with low maintenance.
The Metal Bellows Mechanical Seal is a high-performance, non-pusher shaft sealing component that is engineered to seal fluids between rotating and stationary parts of machinery in challenging industrial applications. In this type of seal there are no traditional springs or sliding elastomer seals, but a flexible metallic bellows assembly that expands or contracts axially while in use.
The metallic bellows has two sealing roles. It supplies the spring force that is required to keep the sealing surfaces of the rotating and stationary parts pressed together continuously.
Secondly, no dynamic O-rings or elastomer motion are needed to provide the leak-proof secondary shaft seal.
One face on a seal rotates with the shaft while the other face is stationary in the housing. A flexible bellows construction ensures constant face pressure in the following situations:
Metal Bellows Mechanical Seals do not have any elastomer sliding along the surface of the shaft, which eliminates problems of shaft wear, fretting, and scoring that occur in conventional pusher seals.
These seals are popular to use when handling:
Metal bellows mechanical seals are widely utilised in refinery pumps, chemical reactors, steam circulation systems, petrochemical processing systems, pharmaceutical plants and other critical applications where conventional elastomer seals are prone to failure from heat or chemical attack.
Common variants include the following:

Technical guidance before & after purchase
The right material pairing directly determines how long a seal lasts and whether it handles your process fluid without failure. Below are the materials available for this seal type — we select or recommend based on your application.
Self-lubricating with good chemical resistance. The standard rotating face material for general-duty and water pump applications.
Exceptional hardness, wear resistance, and chemical compatibility. The preferred mating face material for demanding applications.
Springs, glands, sleeves, and retainer components. Corrosion-resistant structural integrity across all seal types.
Chemical universality — resists virtually all acids, alkalis, and solvents. Used as the bellow element and secondary seal in corrosive duty seals.
Flexible elastomeric bellow that acts as both the drive and secondary seal. Simple, cost-effective, and shaft-friendly.
Replaces elastomeric secondary seals entirely. Ideal for extreme temperatures (cryogenic to +450°C) where no elastomer survives.
Material selection depends on your process fluid, temperature, pressure, and shaft speed. Contact our team for a recommendation specific to your application.
