The mechanical seal IN0280.128PVPGG is a precision-engineered component designed for reliable shaft sealing in rotating equipment. This model belongs to the standardized series found in the catalog of mechanical seals under the category CATALOG OF MECHANICAL SEALS / IN128/IN128P. It is engineered for applications requiring robust performance with a clamping ring (type of seal: с прижимным кольцом), ensuring secure installation and stable operation under various operational conditions.

Constructed for a shaft diameter d1 of 28 mm, the seal features a compact design with a total seal length L3 of 27.5 mm. The critical sealing faces utilize silicon carbide (карбид кремния) for both the fixed and moving parts. This material pairing offers exceptional resistance to abrasion, corrosion, and high temperatures, ensuring long service life and minimal leakage. The metal components are manufactured from AISI304 stainless steel, providing excellent structural integrity and corrosion resistance in demanding environments. The secondary sealing element is made from NBR (nitrile butadiene rubber), a versatile elastomer known for its good resistance to oils, fuels, and a wide temperature range.

The precise dimensions of the mechanical seal are key to its proper function and interchangeability. The external diameter of the fixed part d7 is 43 mm, while the outer diameter of the moving part d3 measures 42 mm. These specific dimensions of the mechanical seal must be carefully matched to the seal chamber or gland plate for a correct fit. The model's designation, seal grade 128P, indicates its specific configuration within the product line, which can be referenced in comprehensive technical documentation and catalogs.

The IN0280.128PVPGG mechanical seal is suitable for a wide array of industrial applications, including pumps, mixers, and compressors handling water, process fluids, and light corrosive media. Its design with a clamping ring facilitates easier installation and maintenance. When selecting a seal, consulting the detailed catalog of mechanical seals is essential to verify all parameters, including the exact dimensions of the mechanical seal, to ensure compatibility with your equipment and optimal sealing performance.
