Mechanical seal IN0140.109K.QQVGG

**Mechanical Seal IN0140.109K.QQVGG**

The IN0140.109K.QQVGG is a high-performance bellows-type mechanical seal designed for reliable operation in demanding industrial environments. As part of the comprehensive IN109K series catalog of mechanical seals, this model is engineered to precise dimensional standards, ensuring compatibility and ease of replacement. Its construction utilizes advanced materials to provide exceptional resistance to wear, corrosion, and a wide range of aggressive media.

**Key Features and Construction**

This seal employs a bellows (сильфонное) design, which offers superior flexibility and compensation for axial and angular shaft misalignments, as well as vibration. The primary sealing faces are manufactured from silicon carbide (карбид кремния) for both the fixed and moving parts. This material pairing ensures excellent dry-running capabilities, high thermal conductivity, and outstanding resistance to abrasion and chemical attack. The metal structural components are made from AISI304 stainless steel, providing robust mechanical strength and general corrosion resistance. The secondary sealing element is a VITON elastomer, known for its exceptional performance in high-temperature applications and compatibility with oils, fuels, and many chemicals.

**Precise Dimensional Specifications**

Accurate dimensions of a mechanical seal are critical for proper installation and function. The IN0140.109K.QQVGG is characterized by the following key installation sizes: a shaft diameter (d1) of 14 mm, an external diameter of the fixed part (d7) of 30.95 mm, and an outer diameter of the moving part (d3) of 28.5 mm. The overall seal length (L3) is 25.4 mm. These precise розміри торцевого ущільнення allow for seamless integration into pump housings and gland plates designed to the 109K seal grade standard, facilitating straightforward maintenance and inventory management.

**Applications and Benefits**

This mechanical seal is suitable for a variety of rotating equipment applications, including centrifugal pumps, mixers, and compressors, handling diverse fluids from water to aggressive process chemicals. The combination of silicon carbide faces and VITON elastomer ensures long service life and reduced maintenance downtime. When selecting a replacement seal, consulting the detailed каталог торцевих ущільнень for the IN109K series is essential to confirm exact model compatibility. The IN0140.109K.QQVGG represents a reliable sealing solution where durability, chemical resistance, and precise dimensional adherence are paramount.
