**Mechanical Seal IN0240.502B.QQVGG: Technical Specifications and Application**

The IN0240.502B.QQVGG is a high-performance bellows-type mechanical seal designed for reliable operation in demanding pumping applications. As part of the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)** for series IN502B, this model is engineered to precise dimensional and material specifications, ensuring optimal compatibility and long service life. The seal's construction utilizes advanced materials to withstand aggressive media, high temperatures, and challenging operational conditions.

**Key Design Features and Construction**
This seal is characterized by its bellows design (type: сильфонное), which provides axial flexibility and compensates for shaft endplay and misalignment. The primary sealing faces are manufactured from карбид кремния (silicon carbide), a material selected for its exceptional hardness, superior wear resistance, and excellent corrosion resistance. Both the fixed part (stationary seat) and the moving part (rotary face) utilize this premium material, promoting stable friction pair performance and minimal leakage over extended periods. The metal structural components are fabricated from AISI304 stainless steel, offering robust mechanical strength and general corrosion resistance. The secondary sealing element is made from VITON fluorocarbon elastomer, known for its high thermal stability and chemical compatibility with a wide range of fluids, including oils, fuels, and many solvents.

**Precise Dimensional Data and Integration**
Accurate **розміри торцевого ущільнення (dimensions of the mechanical seal)** are critical for proper installation and function. The IN0240.502B.QQVGG is designed for a nominal shaft diameter (d1) of 24 mm. The external diameter of the fixed part (d7) is 39 mm, while the outer diameter of the moving part (d3) measures 38 mm. The overall seal length (L3) is 26.7 mm. These standardized dimensions facilitate straightforward selection from the catalog and ensure correct fitment within the seal chamber of compatible pump models.

**Application and Operational Benefits**
The combination of silicon carbide faces, a stainless steel metal structure, and VITON elastomers makes this seal suitable for a broad spectrum of applications. It is commonly employed in chemical processing, petrochemical industries, pharmaceutical production, and general industrial pumping systems handling aggressive or high-purity fluids. The 502B seal grade indicates a specific design configuration optimized for balanced performance in terms of pressure and speed capabilities. The bellows assembly eliminates the need for dynamic O-rings on the shaft, reducing hang-up and providing reliable performance in applications where crystallization or fluid solidification might be a concern.

In summary, the mechanical seal IN0240.502B.QQVGG represents a reliable sealing solution where material integrity and precise engineering are paramount. Its detailed specification within the **каталог торцевих ущільнень** allows for exact technical selection, ensuring system reliability, reduced maintenance downtime, and effective containment of process fluids.
