Mechanical seal IN0300.502B.QQVGG

The mechanical seal IN0300.502B.QQVGG is a bellows-type sealing solution engineered for reliable operation in demanding industrial environments. This model belongs to the standardized IN502B series, a key component within any comprehensive catalog of mechanical seals (каталог торцевих ущільнень) for pumps and rotating equipment. Its design is characterized by a robust construction utilizing high-performance materials to ensure extended service life and minimal maintenance requirements.

Critical to its performance are the precise dimensions of the mechanical seal (розміри торцевого ущільнення). The seal is configured for a shaft diameter (d1) of 30 mm. The moving part features an outer diameter (d3) of 44 mm, while the stationary part has an external diameter (d7) of 45 mm. The overall seal length (L3) is 30.5 mm. These exacting tolerances guarantee a proper fit and optimal sealing function within the designated housing.

Material selection is paramount for corrosion resistance and durability. The primary sealing faces are manufactured from silicon carbide (карбид кремния) for both the moving and fixed parts. This material offers exceptional hardness, excellent wear resistance, and good chemical inertness. The metal structural components are made from AISI 304 stainless steel, providing reliable strength and resistance to oxidation. The secondary sealing element, a critical bellows, is fabricated from VITON fluorocarbon elastomer. This material ensures superior resilience and long-term sealing integrity when exposed to a wide range of aggressive fluids, oils, and elevated temperatures.

As a bellows-type (сильфонное) seal, the IN0300.502B.QQVGG eliminates the need for a dynamic O-ring, reducing friction and potential hang-up points. This design is particularly advantageous in applications involving crystallizing media or where shaft fretting is a concern. The seal is classified under the 502B standard, indicating its specific configuration and interchangeability within this common seal family.

This mechanical seal is suitable for a variety of centrifugal pumps, mixers, and other rotating shaft equipment in chemical processing, petrochemical, pharmaceutical, and general industrial applications. Its construction ensures effective containment of process fluids, prevention of leaks, and protection of bearings from contamination. When selecting a replacement or specifying a new seal, referencing the detailed model number IN0300.502B.QQVGG and its complete dimensional and material attributes is essential for ensuring compatibility and performance.
