Mechanical seal IN0250.110.BVPGG

The mechanical seal IN0250.110.BVPGG is a high-performance bellows-type sealing solution engineered for reliable operation in demanding industrial environments. As part of the comprehensive **каталог торцевих ущільнень** series IN110, this model is designed for precise installation on shafts with a diameter (d1) of 25 mm. Its construction ensures effective containment of fluids and prevention of leaks in pumps, mixers, and other rotary equipment.

This seal features a robust material composition tailored for durability and chemical resistance. The primary sealing face is manufactured from ceramic, providing exceptional hardness and wear resistance against abrasive media. The mating rotating face utilizes graphite, a material chosen for its self-lubricating properties and excellent compatibility with a wide range of fluids. The bellows and secondary sealing elements are made from NBR (Nitrile rubber), offering reliable flexibility and resilience across a standard temperature range. The structural metal components are fabricated from AISI304 stainless steel, ensuring corrosion resistance and long-term structural integrity.

Critical **розміри торцевого ущільнення** are precisely defined for correct selection and installation. The external diameter of the fixed part (d7) is 40 mm, while the outer diameter of the moving part (d3) measures 44.2 mm. The overall seal length (L3) is 16 mm. These dimensions are standardized within the catalog to facilitate easy replacement and interchangeability. The seal is classified under grade 110, indicating its specific performance and design characteristics within the product line.

The bellows-type design of the IN0250.110.BVPGG mechanical seal compensates for axial shaft movement and minor misalignments, maintaining consistent face contact and sealing performance. This design is particularly advantageous in applications where vibration or thermal expansion may occur. The combination of ceramic and graphite faces ensures stable operation with minimal friction and heat generation. When consulting the **каталог торцевих ущільнень** for a suitable replacement or a new application, the detailed specifications of this model, including shaft diameter, material stack, and precise dimensions, allow for accurate technical matching. Proper selection based on these parameters is crucial for achieving optimal service life and preventing equipment downtime.
