The mechanical seal IN0190.108.BVPGG is a bellows-type sealing solution engineered for reliable operation in rotary shaft applications. This model belongs to the standardized IN108 series, a comprehensive line featured in any professional catalog of mechanical seals (каталог торцевих ущільнень). Its design is characterized by precise dimensional parameters, ensuring compatibility and ease of installation. The critical dimensions of the mechanical seal (розміри торцевого ущільнення) include a shaft diameter (d1) of 19 mm, an outer diameter of the moving part (d3) of 33 mm, and an external diameter of the fixed part (d7) of 35 mm. The overall seal length (L3) is 19.2 mm.

Construction of the IN0190.108.BVPGG utilizes a material combination selected for durability and chemical resistance. The primary sealing faces consist of a stationary part manufactured from ceramic, offering high hardness and wear resistance, paired with a moving part made of graphite, which provides excellent self-lubricating properties. The metal structural components are fabricated from AISI304 stainless steel, ensuring corrosion resistance in various industrial environments. The elastic element is a bellows made from NBR (Nitrile Butadiene Rubber), suitable for a wide range of fluids including oils, water, and certain chemicals.

This seal is designed for applications where space is constrained and reliable sealing of pumps, mixers, or agitators is required. The bellows design compensates for axial shaft movement and minor misalignments, maintaining consistent face loading and sealing integrity. The specific material selection makes the IN0190.108.BVPGG applicable in general industrial services, water handling, and chemical processing at moderate temperatures and pressures compatible with NBR and the stated face materials. When selecting from a catalog of mechanical seals, the precise dimensions of the mechanical seal are paramount for correct fitment, and this model provides clear specifications for integration into systems with a 19 mm shaft diameter.
