**Mechanical Seal IN0160.74UQQVGG: Technical Description and Specifications**

The IN0160.74UQQVGG is a precision-engineered mechanical face seal designed for reliable shaft sealing in demanding industrial pump applications. This model belongs to the comprehensive **catalog of mechanical seals** series IN71U/IN74U, characterized by a robust construction with a clamping ring (прижимное кольцо), ensuring secure installation and stable operation under varying pressure and rotational speed conditions.

**Key Design and Material Features**
This seal is configured for a nominal shaft diameter (d1) of 16 mm. Its compact design features an external diameter of 27 mm for both the fixed part (d7) and the moving part (d3), with an overall seal length (L3) of 25 mm. These precise **dimensions of the mechanical seal** are critical for ensuring correct fitment and optimal performance within the seal chamber. The primary sealing faces are manufactured from silicon carbide (карбид кремния) for both the stationary and rotating components. This material selection provides exceptional resistance to abrasion, corrosion, and thermal shock, ensuring long service life and minimal leakage. The metal structural components are made from AISI304 stainless steel, offering good corrosion resistance and mechanical strength. The secondary elastomeric sealing element is made from NBR (Nitrile Butadiene Rubber), a versatile material suitable for a wide range of fluids including oils, water, and many industrial chemicals.

**Performance and Application**
Classified under seal grade 74U, the IN0160.74UQQVGG is engineered for applications requiring a balanced approach to durability and chemical compatibility. The inclusion of a clamping ring simplifies assembly and enhances the seal's stability on the shaft, preventing fretting and ensuring consistent face loading. This mechanical seal is suitable for use in various centrifugal pumps, mixers, and other rotating equipment found in chemical processing, water treatment, general industrial fluid transfer, and irrigation systems. Its construction with silicon carbide faces makes it particularly effective in handling fluids with suspended abrasive particles or in conditions prone to dry running.

When selecting a seal from the **catalog of mechanical seals**, precise attention to the provided **dimensions of the mechanical seal**—such as shaft diameter (d1), outer diameters (d3, d7), and length (L3)—is paramount for successful installation. The IN0160.74UQQVGG represents a reliable, standardized solution, combining proven materials and a practical design for effective shaft sealing in standard industrial applications.
