The mechanical seal IN0170.108.BVPGG is a bellows-type sealing solution engineered for reliable operation in rotary shaft applications. This model belongs to the IN108 series, a comprehensive line featured in the catalog of mechanical seals, and is designed for precise installation on shafts with a diameter (d1) of 17 mm. Its construction utilizes a material combination optimized for durability and chemical resistance in various industrial fluids.

Key specifications define the exact dimensions of the mechanical seal, ensuring compatibility and correct fit. The external diameter of the fixed ceramic part (d7) measures 33 mm, while the outer diameter of the moving graphite part (d3) is 32.5 mm. The overall seal length (L3) is 19.7 mm. These precise dimensions of the mechanical seal are critical for proper selection from the catalog and successful integration into pump housings or similar equipment. The seal incorporates a metal component manufactured from AISI304 stainless steel, providing structural integrity and corrosion resistance. The dynamic face consists of graphite, offering excellent self-lubricating properties and wear resistance against the ceramic stationary seat. The secondary sealing element is made from NBR (Nitrile) rubber, suitable for a wide range of oils, water, and fluids within its temperature range.

As a bellows-type seal (сильфонное), the IN0170.108.BVPGG compensates for axial shaft movements and minor misalignments through its flexible metallic bellows, eliminating the need for a dynamic O-ring on the shaft. This design enhances reliability in applications where shaft fretting or clogging of traditional spring designs might be a concern. The material selection—ceramic, AISI304, graphite, and NBR—makes this seal grade 108 unit a versatile choice for general industrial pumping duties involving water, coolants, light oils, and other non-aggressive media. When consulting the catalog of mechanical seals for a replacement or new design, the detailed specifications of this model allow for accurate technical cross-referencing and application engineering.
