The mechanical seal IN0200.125QQVGG 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 is defined by specific dimensions of the mechanical seal, ensuring compatibility and optimal performance.

Manufactured to seal grade 125, this unit is engineered for robust operation. The seal features a design with a clamping ring (type of seal: с прижимным кольцом), which facilitates secure installation and stable positioning on the shaft. The critical sealing faces utilize silicon carbide (карбид кремния) for both the fixed and moving parts. This material pairing provides exceptional resistance to abrasion, excellent chemical inertness, and superior thermal conductivity, ensuring long service life and reliable leakage prevention under various operational conditions.

The structural integrity of the seal is supported by metal components made from AISI304 stainless steel, offering good corrosion resistance. The secondary sealing element is comprised of NBR (Nitrile Butadiene Rubber), a versatile elastomer suitable for a wide range of fluids including oils, water, and certain chemicals, within its temperature limits. The precise dimensional parameters are crucial for correct selection: it is designed for a shaft diameter (d1) of 20 mm. The external diameter of the fixed part (d7) is 35 mm, while the outer diameter of the moving part (d3) measures 34 mm. The overall seal length (L3) is 41 mm. These exact розміри торцевого ущільнення are critical for proper fitting within the seal chamber and alignment with other pump components.

When consulting the каталог торцевих ущільнень, the IN0200.125QQVGG stands out as a dependable choice for standard pump models requiring a 20 mm shaft seal. Its balanced design, combining durable silicon carbide faces with a corrosion-resistant metallic structure and a compatible elastomer, makes it suitable for applications in chemical processing, general industrial water systems, and irrigation. Proper installation according to the specified dimensions ensures maximum efficiency and operational longevity.
