Mechanical seal IN0300.120BVPGG

The mechanical seal IN0300.120BVPGG is a precision-engineered component designed for reliable shaft sealing in a wide range of industrial rotary equipment. This model belongs to the standardized IN120B series, a comprehensive line featured in any professional **каталог торцевих ущільнень**. Its construction ensures long-term performance in pumps, mixers, and agitators handling water, light oils, and various neutral fluids.

Engineered for a shaft diameter (d1) of 30 mm, the seal features a balanced design with critical **розміри торцевого ущільнення** optimized for secure installation and efficient operation. The fixed sealing ring, with an external diameter (d7) of 45 mm, is manufactured from high-grade ceramic, providing exceptional hardness and wear resistance against the moving face. The complementary moving part, crafted from durable graphite, ensures a consistently smooth and low-friction running surface. This pairing of materials guarantees stable sealing performance with minimal heat generation.

The structural integrity of the IN0300.120BVPGG is supported by metal components made from corrosion-resistant AISI304 stainless steel, suitable for many general industrial environments. The dynamic sealing is maintained by a cylindrical spring mechanism, which applies uniform pressure to the sealing faces, compensating for minor axial shaft movements and face wear. The secondary elastomeric seal, made from NBR (Nitrile rubber), offers excellent compatibility with oils and water, ensuring a tight static seal on the shaft or housing. The overall seal length (L3) is precisely 24.5 mm, while the outer diameter of the moving part (d3) is 43 mm, dimensions critical for retrofit applications and housing compatibility.

This mechanical seal is characterized by its robustness and versatility. The 120B seal grade indicates a specific configuration and material set proven in field applications. Its design is focused on ease of maintenance, interchangeability, and providing a cost-effective sealing solution that reduces downtime and prevents fluid leakage. When selecting a seal from the **каталог торцевих ущільнень**, the IN0300.120BVPGG stands out for its clear specification of all essential **розміри торцевого ущільнення** and material properties, enabling precise selection for optimal equipment performance and service life.
