Mechanical seal IN0190.8UQQVGG

The mechanical seal IN0190.8UQQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the IN9U/IN8U series, a comprehensive **каталог торцевих ущільнень** offering standardized solutions for various operational conditions. Manufactured to exacting specifications, it features a robust construction with a balanced selection of materials for enhanced durability and performance.

Key to its functionality are the precise **розміри торцевого ущільнення**, which ensure a correct fit and optimal sealing force. The seal is engineered for a shaft diameter (d1) of 19.05 mm. The stationary part features an external diameter (d7) of 34.93 mm, while the rotating part has an outer diameter (d3) of 34 mm. The overall seal length (L3) is 22.2 mm. These dimensions are critical for proper installation and interchangeability within compatible pump and mixer housings.

The seal's material composition is selected for superior chemical and wear resistance. Both the fixed and moving sealing faces are manufactured from silicon carbide (карбид кремния), providing excellent hardness, thermal conductivity, and corrosion resistance, which minimizes friction and extends service life. The metal structural components are made from AISI 304 stainless steel, offering good general corrosion resistance. The secondary sealing element consists of NBR (Nitrile Butadiene Rubber), a versatile elastomer suitable for a wide range of fluids including oils, water, and many chemicals.

As a type "с прижимным кольцом" (with a clamping ring), the IN0190.8UQQVGG is designed for secure and straightforward mounting, ensuring the stationary seat is positively locked in place. This design enhances operational reliability by preventing any unintended movement. The "8U" seal grade designation indicates a specific configuration within the catalog, characterized by its balanced design and material pairing for general industrial service.

This mechanical seal is suitable for applications in centrifugal pumps, agitators, and compressors across chemical processing, water treatment, and general manufacturing industries. Its construction ensures effective containment of process fluids, prevention of leaks, and protection of bearing arrangements from contamination. When selecting from the **каталог торцевих ущільнень**, verifying the precise **розміри торцевого ущільнення** against your equipment's specifications is essential for ensuring compatibility and achieving the intended performance and longevity.
