Mechanical seal IN0250.104A.BVPGG

The mechanical seal IN0250.104A.BVPGG is a high-precision bellows-type sealing device engineered for reliable operation in demanding industrial environments. This model is a key component within the extensive CATALOG OF MECHANICAL SEALS / IN104/IN104A series, offering a standardized solution for rotating shaft applications. Manufactured by Торцевое уплотнение, it is designed for installation on shafts with a diameter (d1) of 25 mm, ensuring a secure and effective seal.

Constructed for durability and chemical resistance, the seal utilizes a material combination optimized for performance. The primary sealing face is formed by a stationary ceramic ring, providing exceptional hardness and wear resistance. This fixed part has an external diameter (d7) of 41 mm. The mating rotary face is manufactured from high-grade graphite, a self-lubricating material that ensures smooth operation and minimal friction against the ceramic. The metal structural components are made from AISI304 stainless steel, offering excellent corrosion resistance. The bellows and secondary sealing elements are crafted from NBR (Nitrile rubber), known for its good resistance to oils, fuels, and a wide range of fluids.

Critical **розміри торцевого ущільнення** for proper installation and compatibility include an outer diameter of the moving part (d3) of 40 mm and an overall seal length (L3) of 29 mm. These precise dimensions are essential for correct gland or housing fitment and can be referenced within any comprehensive **каталог торцевих ущільнень**. The bellows design (сильфонное) provides inherent flexibility, compensating for axial shaft movement and minor misalignments without compromising the seal integrity. This design eliminates the need for a dynamic O-ring on the shaft, reducing friction and potential hang-up points.

The IN0250.104A.BVPGG, identified by its specific seal grade 104A, is suitable for a variety of pumps, mixers, and compressors handling water, light chemicals, and other non-aggressive media where its material configuration is applicable. Its robust construction and precise engineering ensure extended service life, reduced maintenance downtime, and effective prevention of fluid leakage, safeguarding both equipment and operational processes.
