**Mechanical Seal IN0310.8UQQVGG: Technical Description and Specifications**

The IN0310.8UQQVGG is a precision-engineered mechanical face seal designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the standardized IN9U/IN8U series, a comprehensive catalog of mechanical seals (каталог торцевих ущільнень) known for robust construction and consistent performance. Its design incorporates a pressing ring (с прижимным кольцом), ensuring secure installation and optimal face loading for immediate and effective sealing.

**Construction and Material Composition**
The seal's durability and chemical resistance are defined by its high-grade material selection. Both the stationary and rotating seal faces are manufactured from silicon carbide (карбид кремния), providing exceptional hardness, excellent wear resistance, and stability against a wide range of aggressive media. The metallic structural components are made from AISI304 stainless steel, offering good corrosion resistance and mechanical strength. The secondary sealing element utilizes NBR (Nitrile Butadiene Rubber), a versatile elastomer suitable for applications involving oils, water, and many common industrial fluids.

**Critical Dimensional Data**
Precise dimensions are paramount for correct seal selection and interchangeability. The key размеры торцевого ущільнення for the IN0310.8UQQVGG are as follows:
* **Shaft Diameter (d1):** 31.75 mm.
* **Outside Diameter of the Rotating Part (d3):** 48.3 mm.
* **Outside Diameter of the Stationary Part (d7):** 47.63 mm.
* **Overall Seal Length (L3):** 27 mm.
These standardized dimensions facilitate easy reference within technical documentation and ensure compatibility with corresponding seal housings.

**Performance and Application**
Classified under seal grade 8U, this model is engineered for general industrial service with a balanced performance profile. The combination of silicon carbide faces ensures low friction and minimal heat generation, contributing to extended service life and reduced maintenance downtime. Its typical applications include centrifugal pumps, mixers, and other rotary equipment in sectors such as chemical processing, general industrial water systems, and light-duty hydrocarbon services. The inclusion of a pressing ring simplifies assembly and guarantees correct initial face contact, which is critical for preventing leakage from startup.

The Mechanical Seal IN0310.8UQQVGG represents a reliable, off-the-shelf sealing solution, whose specifications are clearly defined within the industry-standard catalog of mechanical seals for straightforward procurement and replacement.
