The IN0190.E.BQPGG is a bellows-type mechanical seal designed for reliable shaft sealing in a variety of rotary equipment applications. This model belongs to the comprehensive **каталог торцевих ущільнень INE** series, representing a precisely engineered solution where compact dimensions and material compatibility are critical. Its construction ensures effective containment of fluids and prevention of leakage in pumps, mixers, and similar industrial machinery.

This seal is characterized by its specific **розміри торцевого ущільнення**, which guarantee correct installation and optimal performance. The seal is configured for a shaft diameter (d1) of 19.05 mm. The external diameter of the fixed part (d7) measures 34.93 mm, while the outer diameter of the moving part (d3) is 34.1 mm. The overall seal length (L3) is 18.24 mm. These precise dimensions must be verified against the housing and shaft specifications to ensure a proper fit. The seal is classified under grade E, indicating its performance characteristics and suitable operational ranges for pressure and speed.

Material selection is paramount for durability and chemical resistance. The primary sealing face of the fixed part is manufactured from silicon carbide (карбид кремния), a hard, wear-resistant material offering excellent performance against abrasion and corrosion. The corresponding moving part face is made from graphite, providing a self-lubricating and compatible running surface against silicon carbide. The metal structural components are fabricated from AISI 304 stainless steel, ensuring good general corrosion resistance. The elastic element is a bellows constructed from NBR (Nitrile rubber), suitable for a wide range of oils, water, and fluids within its temperature limits.

The **торцевое уплотнение** IN0190.E.BQPGG is engineered for applications requiring a robust bellows-type design, which eliminates the need for a dynamic O-ring on the shaft, reducing hang-up and improving reliability in environments with potential shaft fretting or crystallization. Its compact design is advantageous in space-constrained installations. When selecting a mechanical seal, consulting the detailed **каталог торцевих ущільнень** is essential to match this model's specifications—including all provided dimensions, materials, and the E-class seal grade—with the specific operational requirements of the equipment, such as fluid type, temperature, pressure, and shaft speed. Proper installation and handling are crucial to achieving the designed service life and leak-free operation.
