The mechanical seal IN0130.4702.QQVGG is a high-performance tandem-type sealing solution engineered for demanding industrial applications where reliable shaft sealing is critical. This model belongs to the standardized IN4702 series, a comprehensive range featured in professional catalogs of mechanical seals, designed to offer a reliable and interchangeable component for pump and rotating equipment maintenance.

Constructed for a shaft diameter (d1) of 13 mm, this seal features a compact yet robust design with a total seal length (L3) of 36 mm. The fixed and moving rings share an identical outer diameter of 25 mm (d7 and d3), ensuring a precise and balanced fit within the seal chamber. The primary sealing faces are manufactured from silicon carbide (карбид кремния), a material selected for its exceptional hardness, superior wear resistance, and excellent chemical inertness. This pairing provides outstanding durability and stable leakage control, even in abrasive or corrosive media. The structural metal components are made from AISI 304 stainless steel, offering good general corrosion resistance and mechanical strength. The secondary elastomeric sealing element utilizes VITON (FKM) rubber, known for its high-temperature stability and broad chemical compatibility, particularly with hydrocarbons and aggressive fluids.

The tandem configuration is a key feature of this seal, consisting of two sets of sealing faces arranged in series. This design creates a barrier chamber between the seals, which can be used for a buffer or barrier fluid. This significantly enhances operational safety by providing a secondary containment layer, making the IN0130.4702.QQVGG ideal for applications involving hazardous, toxic, or environmentally sensitive process fluids where zero emission is a priority. The precise dimensions of the mechanical seal, including the 25 mm outer diameters and 36 mm length, are critical for correct installation and optimal performance, underscoring the importance of consulting detailed dimensional drawings within the catalog of mechanical seals.

In summary, the mechanical seal IN0130.4702.QQVGG delivers reliable, long-lasting performance for pumps, mixers, and compressors in chemical processing, petrochemical, and pharmaceutical industries. Its tandem design with silicon carbide faces, VITON elastomers, and stainless steel construction ensures maximum reliability in challenging service conditions. For proper selection and installation, always verify the exact dimensions of the mechanical seal against equipment specifications.
