The mechanical seal IN0250.125QQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the IN125 series, a comprehensive **каталог торцевих ущільнень** offering standardized solutions for pump and rotating equipment. Manufactured to exacting specifications, it ensures optimal performance and extended service life in systems handling various fluids.

Constructed for a nominal shaft diameter (d1) of 25 mm, this seal features a robust design with a compression ring. Its key dimensions, including a moving part outer diameter (d3) of 39 mm and a fixed part outer diameter (d7) of 40 mm, are critical **розміри торцевого ущільнення** for ensuring correct installation and fit within the seal chamber. The overall seal length (L3) is 43 mm. The primary sealing faces utilize silicon carbide (карбид кремния) for both the moving and fixed parts. This material pairing delivers exceptional resistance to abrasion, corrosion, and thermal shock, ensuring stable sealing face contact and minimal wear over time. The metal structural components are fabricated from AISI304 stainless steel, providing excellent general corrosion resistance and structural integrity. The secondary elastomeric seal is made from NBR (Nitrile Butadiene Rubber), a material chosen for its good compatibility with a wide range of oils, water, and fluids within its operational temperature range.

The IN0250.125QQVGG is classified under seal grade 125, indicating its suitability for standard duty applications across chemical processing, general industrial pumping, water treatment, and irrigation systems. The inclusion of a compression ring simplifies installation and maintenance procedures, promoting a secure and uniform load on the sealing faces. This design enhances operational reliability by preventing leakage and reducing downtime. When selecting a mechanical seal, consulting the detailed **каталог торцевих ущільнень** is essential to match the model's **розміри торцевого ущільнення** and material configuration with your specific operational parameters, including pressure, temperature, and fluid media. The IN0250.125QQVGG represents a balanced solution, combining durable materials, precise engineering, and a practical design for consistent sealing performance.
