Mechanical seal IN0350.502B.QQVGG

The mechanical seal IN0350.502B.QQVGG is a high-performance bellows-type sealing solution engineered for demanding industrial applications. This model belongs to the standardized IN502B series, a comprehensive range featured in modern catalogs of mechanical seals, designed to ensure reliable operation and extended service life for rotating equipment. Its precise construction adheres to critical dimensional parameters, making the accurate selection of seal dimensions a fundamental step for optimal performance and leak-free operation.

Constructed for durability and chemical resistance, the seal incorporates stationary and rotating faces manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and stability in aggressive media. The metallic structural components are made from AISI304 stainless steel, providing robust mechanical support and good corrosion resistance. The dynamic sealing is achieved via a bellows assembly manufactured from VITON fluorocarbon elastomer, which offers superior resilience and excellent compatibility with a wide range of oils, fuels, and chemicals, even at elevated temperatures.

Key technical specifications define its application scope. The seal is designed for a nominal shaft diameter (d1) of 35 mm. The external diameter of the stationary part (d7) is 50 mm, while the outer diameter of the rotating part (d3) measures 49 mm. The overall seal length (L3) is 30.5 mm. These precise dimensions of the mechanical seal are critical for correct installation and fit within the seal chamber, ensuring proper face loading and alignment. The bellows design (сильфонное) compensates for axial shaft movement, vibration, and minor misalignments, maintaining consistent face contact.

The IN0350.502B.QQVGG is suitable for use in pumps, mixers, and compressors across various industries, including chemical processing, petrochemical, and general industrial fluid handling. Its material combination and 502B seal grade make it a reliable choice for sealing challenging fluids where standard elastomers would fail. When consulting the catalog of mechanical seals for a replacement or upgrade, this model represents a technically advanced solution where precise dimensions, material integrity, and a robust bellows design converge to ensure operational reliability and minimize maintenance downtime.
