The mechanical seal IN0200.FBC.BVPGG is a bellows-type sealing solution engineered for reliable operation in rotary shaft applications. This model belongs to the IN1/INFBC series within the comprehensive catalog of mechanical seals, designed to meet precise dimensional and material specifications for optimal performance. Its construction is defined by a shaft diameter (d1) of 20 mm, with the fixed part featuring an external diameter (d7) of 34 mm and the moving part an outer diameter (d3) of 33 mm. The overall seal length (L3) is 34 mm, ensuring a compact and efficient design. These critical dimensions of the mechanical seal are essential for correct installation and function, guaranteeing compatibility with standard pump and mixer housings.

Material selection in the IN0200.FBC.BVPGG seal is tailored for durability and chemical resistance. The primary sealing face is provided by a ceramic fixed part, known for its exceptional hardness and wear resistance. The complementary moving ring is manufactured from graphite, offering excellent self-lubricating properties and thermal conductivity for stable face performance. The metal structural components are made from AISI304 stainless steel, providing robust corrosion resistance. The elastomeric element, a bellows in this design, is constructed from NBR (Nitrile Butadiene Rubber), which ensures flexibility and reliable secondary sealing across a wide range of fluids and temperatures typical for industrial applications.

As a bellows-type (сильфонное) seal, the IN0200.FBC.BVPGG eliminates the need for a dynamic O-ring, reducing friction and hang-up tendencies. This makes it particularly suitable for applications involving crystallizing media, high-temperature fluids, or where minimal shaft fretting is required. The FBC seal grade designation indicates a specific configuration optimized for standardized industrial use. When consulting the catalog of mechanical seals, engineers can confidently select this model for its precise engineering, material integrity, and proven design. Its application is widespread in chemical processing, water treatment, and general industrial pumping equipment requiring a dependable seal for a 20 mm shaft.
