PTFE bellows seals are very popular because PTFE material has very good chemical inertness and corrosion resistance to concentrated acids, alkalis and aggressive solvents. A flexible bellows design also eliminates sliding secondary seals, helping to prevent shaft wear and seal hang-up issues.
Face combinations of premium-grade PTFE, Glass Filled PTFE, PFA Lined materials, Silicon Carbide, Carbon, Ceramic and Tungsten Carbide are used to manufacture our seals for ultimate durability and wear resistance. Our PTFE Bellows Mechanical Seals are known for their contamination-free operation, their high level of chemical compatibility, their smooth sealing and their long service life, which makes them a preferred choice for industries.
A PTFE Bellows Mechanical Seal is a special sealing tool that is used for extremely corrosive chemicals and aggressive industrial fluids and is a non-pusher shaft sealing device. This seal has a flexible PTFE (Polytetrafluoroethylene / Teflon) accordion bellows as the spring mechanism and secondary seal.
The PTFE bellows is compressed and expanded in an axial direction to ensure that the rotating and stationary seal faces are always in contact to prevent leakage between the rotating shaft and the stationary face. The bellows holds the shaft in a static position, thus eliminating any dynamic slide of the shaft surface to cause damage or friction-related wear.
The excellent resistance to highly concentrated acids, alkalis, solvents, and corrosive chemicals is among the greatest benefits of PTFE Bellows Mechanical Seals. PTFE material is chemically stable and will not deteriorate quickly in aggressive media where conventional rubber elastomers and stainless steel components will deteriorate quickly.
These seals are widely employed in chemical transfer pumps, acid circulation systems, pharmaceutical reactors, steel pickling lines, chemical dosing equipment and solvent handling. PTFE Bellows Mechanical Seals are offered in Externally Mounted, Internally Mounted, Integral Face and Composite Face configurations for pressures and chemical compatibility.
The PTFE Bellows Mechanical Seal assembly consists of the following major components: PTFE bellows assembly, rotating seal face, stationary seat, gland plate, drive mechanism, and high-performance face materials (Silicon Carbide, Carbon, Ceramic or Tungsten Carbide). These components have excellent chemical resistance, dimensional stability and many years of operational service life in severe industrial conditions.
PTFE Bellows Mechanical Seals are available in multiple configurations to suit different industrial applications and chemical processing requirements.
PTFE Bellows Mechanical Seals provide a number of advanced features for corrosive chemical processing operations.
While quite effective in chemical applications, PTFE Bellows Mechanical Seals have some operating restrictions.
The PTFE Bellows Mechanical Seal Price in India varies depending on its size, pressure rating, PTFE grade, material type of face, temperature range, and application conditions. We at Arohan Seals offer high-quality PTFE sealing solutions at very competitive prices, with the highest quality of industrial performance and service life.
Glass Filled PTFE and PFA Lined Mechanical Seals are found to be more resistant to chemicals, dimensionally stable, and wear-resistant in industries which process highly corrosive chemicals. High performance face materials such as Silicon Carbide and Tungsten Carbide can also have an impact on the seal price.
Economical PTFE Bellows Mechanical Seal models are offered for standard chemical applications and advanced high-performance models are offered for more aggressive industrial applications.

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.
