Mechanical seal IN0220.560С.BQVGG

**Mechanical Seal IN0220.560С.BQVGG: Technical Description and Specifications**

The IN0220.560С.BQVGG is a high-performance bellows-type mechanical seal designed for reliable shaft sealing in demanding industrial applications. As part of the comprehensive CATALOG OF MECHANICAL SEALS / IN560C/INBIA series, this model exemplifies precision engineering and robust material selection to ensure extended service life and minimal maintenance requirements. Manufactured by Торцевое уплотнение, it is engineered to exacting standards for consistent performance.

**Key Design Features and Construction**

This seal is classified under the 560C seal grade, indicating its specific design configuration and performance envelope. Its primary sealing faces utilize a durable material pairing: the fixed ring is manufactured from silicon carbide (карбид кремния), offering exceptional hardness and wear resistance, while the moving ring is crafted from graphite, providing excellent self-lubricating properties and thermal conductivity. This combination ensures stable operation under varying pressure and temperature conditions, minimizing face wear and leakage.

The metal structural components are made from AISI304 stainless steel, providing excellent corrosion resistance in a wide range of common industrial fluids. The secondary sealing element, a bellows, is constructed from NBR (Nitrile rubber), which offers reliable flexibility and sealing performance with oils, water, and many chemicals. The bellows design (сильфонное type) compensates for axial shaft movement and minor misalignments without the need for a dynamic O-ring, enhancing reliability.

**Precision Dimensions for Accurate Fitment**

Critical to its integration is adherence to precise **розміри торцевого ущільнення** (mechanical seal dimensions). The IN0220.560С.BQVGG is designed for a nominal shaft diameter (d1) of 22 mm. The external diameter of the fixed part (d7) measures 37 mm, and the outer diameter of the moving part (d3) is 36 mm. The overall seal length (L3) is 27.5 mm. These dimensions are essential for correct installation within the seal chamber and ensure optimal function without interference.

**Application and Benefits**

This mechanical seal is suitable for a variety of rotary equipment, including pumps, mixers, and compressors, handling non-abrasive fluids where chemical compatibility of NBR, AISI304, and the face materials is confirmed. Its design prioritizes long-term sealing integrity, reducing the frequency of replacements and associated downtime. The use of premium materials like silicon carbide and graphite directly contributes to lower friction, reduced power consumption, and enhanced thermal management at the seal faces.

For engineers and maintenance specialists consulting the **каталог торцевих ущільнень** (catalog of mechanical seals), the IN0220.560С.BQVGG represents a standardized, reliable solution. Its clear specification allows for straightforward identification and cross-referencing, ensuring correct part selection for shaft sealing applications requiring a 22 mm diameter, bellows-type construction with advanced face materials. Proper installation in accordance with these specifications is crucial for achieving the seal's full performance potential.
