The mechanical seal IN0300.125QQVGG is a precision-engineered component designed for reliable shaft sealing in demanding industrial applications. This model belongs to the IN125 series within the comprehensive catalog of mechanical seals, offering a standardized solution for pumps and rotating equipment. Its construction ensures effective containment of fluids, prevention of leaks, and long-term operational stability.

This seal features a robust design with a clamping ring (type of seal: с прижимным кольцом), which facilitates secure installation and maintains proper alignment during service. Critical dimensions include a shaft diameter (d1) of 30 mm, an external diameter of the fixed part (d7) of 45 mm, and an outer diameter of the moving part (d3) of 44 mm. The overall seal length (L3) is 45 mm. These precise dimensions of the mechanical seal are crucial for correct fitment and optimal performance within the designated housing.

Material selection is paramount for durability and chemical resistance. The primary sealing faces utilize silicon carbide (карбид кремния) for both the fixed and moving parts. This material offers exceptional hardness, excellent wear resistance, and good thermal conductivity, making it suitable for abrasive or corrosive media. The metal structural components are manufactured from AISI 304 stainless steel, providing strength and general corrosion resistance. The elastomeric element is made from NBR (Nitrile Butadiene Rubber), a material chosen for its good compatibility with oils, fuels, and water across a wide temperature range.

As part of the seal grade 125, this model is engineered to meet specific pressure and velocity parameters, ensuring reliability in standardized pumping conditions. Its design is integral for maintenance and repair operations, providing a direct replacement seal that restores equipment integrity. When consulting the catalog of mechanical seals, the IN0300.125QQVGG represents a key option for applications requiring a 30 mm shaft seal with high-performance materials. The correct interpretation of the mechanical seal dimensions guarantees interchangeability and system compatibility, reducing downtime and ensuring efficient sealing performance in various industrial fluid handling systems.
