Mechanical seal IN0080.1120ABVPGG

**Mechanical Seal IN0080.1120ABVPGG: Technical Description and Specifications**

The IN0080.1120ABVPGG is a precision-engineered mechanical face seal designed for reliable shaft sealing in rotary equipment. This model belongs to the standardized IN120A series, a comprehensive range featured in industrial **каталог торцевих ущільнень** (catalogs of mechanical seals). It is engineered to prevent fluid leakage in pumps, mixers, and similar apparatus by maintaining consistent contact between its precisely lapped sealing faces.

**Key Design Features and Material Composition**

This seal employs a robust cylindrical spring design (type: циллиндрическая пружина), ensuring uniform axial load and stable performance across a range of operational conditions. The material selection is critical for compatibility and durability. The primary sealing face is formed by a stationary part made of graphite, which offers excellent self-lubricating properties, paired with a rotating part manufactured from high-grade ceramic (moving part material: керамика), renowned for its exceptional hardness and corrosion resistance. The metal structural components are constructed from AISI304 stainless steel, providing strength and broad chemical resistance. The secondary elastomeric sealing element is made from NBR (nitrile butadiene rubber), suitable for a wide variety of oils, water, and fluids within its temperature range.

**Precise Dimensional Data and Integration**

Accurate **розміри торцевого ущільнення** (mechanical seal dimensions) are paramount for correct installation and function. The IN0080.1120ABVPGG is designed for a nominal shaft diameter (d1) of 8 mm. The external diameter of the fixed part (d7) measures 17.1 mm, while the outer diameter of the rotating ceramic part (d3) is 16 mm. The overall seal length (L3) is 15 mm. These precise dimensions ensure a proper fit within the seal chamber and correct alignment on the shaft, which is essential for achieving the intended sealing performance and service life.

**Application and Grade Information**

Classified under seal grade 120A, this model represents a versatile and widely applicable design. Its construction makes it suitable for use in various light to medium-duty industrial applications involving water, coolants, light oils, and other non-aggressive media. The combination of ceramic and graphite faces ensures smooth running and minimal wear, contributing to extended maintenance intervals. When selecting a seal from a **каталог торцевих ущільнень**, the IN0080.1120ABVPGG stands out for applications requiring a compact, reliable sealing solution for an 8 mm shaft, where its specific material compatibility and dimensional accuracy are decisive factors for system integrity.
