The mechanical seal IN0150.1155BVPGG is a precision-engineered sealing solution designed for reliable operation in rotary shaft applications. This model belongs to the standardized IN1155 series, a comprehensive range featured in industrial catalogs of mechanical seals, known for its consistent quality and dimensional interchangeability. Its primary function is to prevent fluid leakage in pumps, mixers, and other equipment where a rotating shaft passes through a stationary housing.

Constructed for durability and chemical resistance, the seal utilizes a multi-material design. The stationary face is manufactured from graphite, providing excellent self-lubricating properties and thermal conductivity. The rotating seal face is made from high-grade ceramic, ensuring exceptional hardness and wear resistance against abrasive media. The metallic components are fabricated from AISI304 stainless steel, offering robust corrosion resistance. The secondary sealing element consists of NBR (Nitrile Butadiene Rubber), a versatile elastomer suitable for a wide range of oils, water, and fluids within its operational temperature range.

Key dimensional parameters of this mechanical seal are critical for correct installation and performance. The seal is engineered for a shaft diameter (d1) of 15 mm. The external diameter of the fixed part (d7) measures 26.9 mm, while the outer diameter of the moving part (d3) is 29 mm. The overall seal length (L3) is 23 mm. These precise **розміри торцевого ущільнення** (mechanical seal dimensions) must be verified against the equipment's gland cavity to ensure a proper fit. The actuation mechanism employs a conical spring design, which provides uniform face loading and reliable sealing force, even in applications with minor axial shaft movement.

The IN0150.1155BVPGG is classified under seal grade 1155, indicating its specific configuration and material set. This model is an essential component for maintenance and repair operations, commonly sourced from detailed **каталог торцевих ущільнень** (catalogs of mechanical seals) for precise part identification. Its typical applications include centrifugal pumps for water treatment, chemical processing, irrigation, and general industrial fluid handling systems where a 15mm shaft diameter is standard. Proper selection based on media compatibility, pressure, and speed ratings is recommended to ensure optimal service life and leak-free performance.
