**Product Description: Mechanical Seal IN0140.108.BVPGG**

The IN0140.108.BVPGG is a bellows-type mechanical seal designed for reliable shaft sealing in rotary equipment. As part of the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)** series IN108, this model offers a precise engineering solution for applications requiring a compact and durable seal assembly. Its construction utilizes a combination of high-performance materials to ensure operational stability and extended service life under demanding conditions.

**Design and Construction Features**
This seal is classified as a bellows (сильфонное) type, which provides inherent flexibility and compensation for axial shaft movements and face wear. The fixed sealing ring is manufactured from ceramic, offering exceptional hardness and superior resistance to abrasion and corrosion. The complementary moving ring is crafted from graphite, a material selected for its excellent self-lubricating properties and thermal conductivity, promoting a stable sealing interface. The metallic structural components are made from AISI304 stainless steel, ensuring good corrosion resistance and mechanical strength. The secondary sealing element consists of an NBR (Nitrile) rubber bellows, which provides reliable static and dynamic sealing with good compatibility with a range of oils, water, and fluids.

**Precise Dimensional Specifications**
The **розміри торцевого ущільнення (dimensions of the mechanical seal)** are critical for correct installation and performance. The IN0140.108.BVPGG is engineered for a nominal shaft diameter (d1) of 14 mm. The external diameter of the fixed part (d7) is 26 mm, while the outer diameter of the moving part (d3) measures 25.5 mm. The overall seal length (L3) is 19.7 mm. These precise dimensions guarantee a proper fit within the seal chamber, facilitating easy installation and optimal function.

**Application and Benefits**
This mechanical seal is suitable for a wide array of pumps, mixers, and other rotating shaft equipment used in general industrial, chemical, and water handling applications. The combination of ceramic and graphite faces ensures reliable performance with minimal friction and wear. The AISI304 and NBR construction provides a balanced solution for environments with moderate chemical and thermal exposure. As a standardized model from the IN108 catalog, the IN0140.108.BVPGG ensures interchangeability and simplifies the maintenance and procurement process for engineers and technicians.

In summary, the mechanical seal IN0140.108.BVPGG represents a robust and precisely manufactured component, where material selection and exact dimensional accuracy converge to deliver dependable sealing performance and operational longevity.
