**Mechanical Seal IN0120.120MBPGG: A High-Performance Cylindrical Spring Seal for Precision Applications**

The IN0120.120MBPGG is a robust mechanical face seal engineered for reliable operation in demanding industrial environments. As part of the comprehensive **каталог торцевих ущільнень (catalog of mechanical seals)** series IN120M, this model exemplifies a standardized design focused on dimensional accuracy and material durability. It is specifically configured for sealing rotating shafts, preventing fluid leakage in pumps, mixers, and compressors.

**Technical Specifications and Construction**
This seal is designed for a nominal shaft diameter (d1) of 12 mm. Its construction features a stationary part with an external diameter (d7) of 23 mm and a rotating part with an outer diameter (d3) of 22 mm. The overall **розміри торцевого ущільнення (dimensions of the mechanical seal)**, including a critical seal length (L3) of 17.5 mm, ensure compatibility with standard housing geometries. The primary sealing faces are manufactured from graphite, providing excellent self-lubricating properties, low friction, and strong resistance to thermal shock. The metallic structural components are made from corrosion-resistant AISI304 stainless steel, guaranteeing longevity in various media. The secondary elastomeric seal is crafted from NBR (Nitrile Butadiene Rubber), offering reliable static sealing and good resistance to oils and water. The actuation force is provided by a **циллиндрическая пружина (cylindrical spring)**, ensuring consistent face loading and stable performance under variable operational conditions.

**Key Features and Operational Benefits**
* **Precision Engineering:** The defined seal grade 120M indicates a standardized configuration within the catalog, ensuring repeatable performance and ease of selection.
* **Durable Material Composition:** The combination of graphite faces, AISI304 metal, and NBR elastomer creates a seal suitable for a wide range of applications, including those involving water, mild chemicals, and oils.
* **Reliable Spring Design:** The cylindrical spring type delivers uniform axial pressure, maintaining optimal contact between sealing faces to minimize leakage.
* **Simplified Selection:** As a documented part of the IN120M series, this seal facilitates straightforward identification and replacement, reducing equipment downtime.

**Typical Applications**
The Mechanical Seal IN0120.120MBPGG is ideally suited for general industrial service in centrifugal pumps, rotary shaft equipment, and fluid transfer systems where reliable sealing for a 12 mm shaft is required. Its material compatibility makes it a versatile choice for maintenance and OEM applications across various sectors, including chemical processing, water treatment, and general manufacturing. When consulting the **каталог торцевих ущільнень**, this model represents a fundamental solution for standard sealing requirements, characterized by its proven design and precise dimensional parameters.
