The mechanical seal IN0280.502B.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 the catalog of mechanical seals, designed to offer reliable containment of process fluids in pumps, mixers, and agitators. Its construction prioritizes durability and chemical resistance, ensuring stable operation under challenging conditions.

Key to its performance are the precisely defined dimensions of the mechanical seal. The unit is configured for a shaft diameter (d1) of 28 mm, with an external diameter of the fixed part (d7) measuring 43 mm and the outer diameter of the moving part (d3) at 42 mm. The overall seal length (L3) is 30 mm. These critical dimensions of the mechanical seal ensure proper fitment and function within the designated housing, preventing leakage paths and guaranteeing optimal sealing face alignment.

Material selection is paramount for the IN0280.502B.QQVGG's reliability. Both the fixed and moving sealing faces are manufactured from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and compatibility with a wide spectrum of abrasive and corrosive media. The metal structural components are made from AISI 304 stainless steel, providing robust mechanical strength and good corrosion resistance. The dynamic sealing element is a bellows (сильфонное) constructed from VITON fluorocarbon elastomer, selected for its superior resilience and excellent resistance to high temperatures, oils, fuels, and many aggressive chemicals.

As a representative model from the catalog of mechanical seals IN502B, this unit is designed for ease of selection and replacement. The 502B seal grade indicates a specific design configuration suitable for a variety of standard pump models. The bellows-type design accommodates axial shaft movement and minor misalignments without compromising the seal integrity. The combination of silicon carbide faces and VITON elastomer makes the IN0280.502B.QQVGG particularly effective in applications involving petrochemicals, hot water, and certain acidic or alkaline solutions where other materials may degrade.

In summary, the mechanical seal IN0280.502B.QQVGG delivers a dependable sealing solution through its precise engineering, high-grade materials, and standardized design. Its specified dimensions and material properties make it a technically sound choice for maintenance engineers and procurement specialists seeking a durable and chemically resistant bellows seal for industrial rotating equipment.
