**Mechanical Seal IN0180.108.BVPGG: Technical Description and Specifications**

The IN0180.108.BVPGG is a bellows-type mechanical seal engineered for reliable shaft sealing in rotary equipment. Designed according to the standardized 108 seal grade, this model offers a robust solution for a wide range of industrial pumping applications, including centrifugal pumps, mixers, and agitators. Its construction ensures effective containment of process fluids, prevention of leaks, and extended service life for rotating machinery.

**Construction and Material Composition**
This seal features a precision-engineered material configuration for balanced performance and chemical compatibility. The stationary face is manufactured from ceramic, providing exceptional hardness and wear resistance against abrasive media. The rotating face utilizes graphite, a self-lubricating material that ensures smooth operation and effective sealing under varying conditions. The critical metal components are fabricated from AISI304 stainless steel, offering excellent corrosion resistance. The secondary sealing element is made from NBR (Nitrile Butadiene Rubber), a versatile elastomer suitable for a broad spectrum of oils, water, and fluids within its operational temperature range.

**Key Dimensional Parameters**
Accurate **розміри торцевого ущільнення** are paramount for correct installation and optimal function. The IN0180.108.BVPGG is designed for a nominal shaft diameter (d1) of 18 mm. The external diameter of the fixed part (d7) measures 33 mm, while the outer diameter of the moving part (d3) is 32.5 mm. The overall seal length (L3) is 19.7 mm. These precise dimensions ensure a proper fit within the seal chamber and correct alignment on the shaft, which is critical for maintaining seal integrity.

**Operational Advantages and Application**
The bellows (**сильфонное**) design eliminates the need for a dynamic O-ring on the shaft, reducing friction and enabling effective performance in applications with minor shaft runout or vibration. This makes the IN0180.108.BVPGG a suitable choice for demanding environments. Its material selection provides a balance of chemical resistance, thermal stability, and mechanical durability. When selecting a seal, consulting the comprehensive **каталог торцевих ущільнень** is essential to match the model, such as the IN0180.108.BVPGG, to the specific fluid properties, pressure, temperature, and speed conditions of the application.

**Model Identification and Category**
This seal is cataloged under the reference IN0180.108.BVPGG and belongs to the product family **CATALOG OF MECHANICAL SEALS / IN108**. It represents a standardized, high-quality component for maintenance and OEM assembly, ensuring equipment reliability and operational safety.
