The mechanical seal IN0250.9BQQVGG is a high-performance sealing solution engineered for demanding industrial applications. This model belongs to the comprehensive CATALOG OF MECHANICAL SEALS within the IN9B/IN8B series, designed to ensure reliable operation and extended service life for rotating equipment. Its precise construction and material selection make it a critical component for preventing fluid leakage in pumps, mixers, and agitators.

This seal is characterized by its robust design featuring a clamping ring (type of seal: с прижимным кольцом), which guarantees secure installation and stable performance under variable operational conditions. The key dimensions of the seal are meticulously defined: it is engineered for a shaft diameter d1 of 25.4 mm. The overall seal length L3 is 35 mm, with the moving part having an outer diameter d3 of 43.5 mm and the fixed part featuring an external diameter d7 of 44.45 mm. These precise **розміри торцевого ущільнення** are crucial for correct selection and interchangeability, ensuring a perfect fit within the designated housing.

Material composition is a cornerstone of the IN0250.9BQQVGG's durability. Both the stationary and rotating faces are manufactured from silicon carbide (карбид кремния), providing exceptional resistance to abrasion, corrosion, and high temperatures, which minimizes wear and maintains sealing integrity. The metal structural components are made from AISI304 stainless steel, offering excellent corrosion resistance and mechanical strength. The secondary sealing element utilizes NBR (Nitrile Butadiene Rubber), a material chosen for its reliable elasticity and compatibility with a wide range of oils, water, and hydraulic fluids.

As a representative model from the detailed **каталог торцевих ущільнень**, the IN0250.9BQQVGG with seal grade 9B is tailored for applications requiring a balanced combination of chemical inertness and mechanical robustness. Its design is suitable for use in chemical processing, general industrial pumping, and water treatment systems. The integration of premium materials like silicon carbide for the sealing faces directly translates to reduced maintenance intervals, lower total cost of ownership, and enhanced operational safety by effectively containing process fluids.
