Mechanical seal IN0200.560B.BVPGG

**Mechanical Seal IN0200.560B.BVPGG: Technical Description and Specifications**

The IN0200.560B.BVPGG is a bellows-type mechanical seal engineered for reliable shaft sealing in a wide range of rotary equipment. As part of the standardized IN560B series, this model offers a robust and compact sealing solution, designed for precise installation and consistent performance in demanding industrial environments. Its construction is defined by carefully selected materials and exact dimensions, ensuring compatibility and durability.

**Key Design Features and Construction Materials**

This seal employs a bellows (сильфонное) design, which provides axial flexibility and eliminates the need for a dynamic O-ring on the shaft, reducing hang-up and improving response to shaft runout and end play. The primary sealing faces are formed by a stationary ceramic ring and a rotating graphite ring. The ceramic component offers exceptional hardness and corrosion resistance, while the graphite moving part provides excellent self-lubricating properties and thermal conductivity. The metal structural components are manufactured from AISI304 stainless steel, ensuring good corrosion resistance in many common media. The secondary elastomeric sealing element is made from NBR (Nitrile Butadiene Rubber), a material chosen for its reliable performance with oils, water, and many industrial fluids across a standard temperature range.

**Precise Dimensional Data and Integration**

Accurate **розміри торцевого ущільнення** are critical for proper fit and function. The IN0200.560B.BVPGG is designed for a nominal shaft diameter (d1) of 20 mm. The external diameter of the stationary part (d7) is 38.1 mm, and the outer diameter of the rotating part (d3) measures 36 mm. The overall seal length (L3) is 23.8 mm. These precise dimensions must be verified against the equipment's gland cavity and shaft specifications to guarantee correct installation. Consulting the comprehensive **каталог торцевих ущільнень** for the IN560B series is recommended to confirm the exact geometry and identify potential alternative configurations or installation guidelines.

**Application and Operational Benefits**

The IN0200.560B.BVPGG mechanical seal is suitable for various pumps, mixers, and other rotating shaft applications in chemical processing, general industrial water systems, and light-duty hydrocarbon services. The combination of ceramic and graphite faces ensures stable sealing with minimal friction, while the bellows design compensates for wear and minor misalignment. Its standardized design facilitates easier selection and replacement from product catalogs, helping to minimize equipment downtime. When selecting this seal, ensure the fluid characteristics, pressure, temperature, and shaft speed are within the operational limits defined for the 560B seal grade and its constituent materials (ceramic, AISI304, graphite, and NBR).
