Mechanical seal IN0150.E.BQPGG

**Mechanical Seal IN0150.E.BQPGG**

The IN0150.E.BQPGG is a high-performance bellows-type mechanical seal designed for reliable shaft sealing in demanding industrial applications. This model is a part of the comprehensive INE series, featured in our extensive catalog of mechanical seals, which provides engineers and maintenance specialists with a wide selection of standardized sealing solutions. Its precise construction ensures compatibility with pumps, mixers, and other rotary equipment requiring a robust and durable seal.

**Technical Specifications and Construction**
This seal is engineered for a nominal shaft diameter (d1) of 15.87 mm. The critical sealing faces are manufactured from advanced materials to ensure longevity and stable operation. The fixed ring is constructed from silicon carbide (карбид кремния), a material renowned for its exceptional hardness, wear resistance, and chemical inertness. The complementary moving ring is made from high-grade graphite, providing excellent self-lubricating properties and a reliable running surface. The metal structural components are fabricated from corrosion-resistant AISI304 stainless steel, while the elastomeric bellows is made from NBR (Nitrile rubber), offering good resistance to oils and a wide operating temperature range. The precise dimensions of the seal, including an external diameter of the fixed part (d7) at 31.75 mm, an outer diameter of the moving part (d3) at 30.9 mm, and a total seal length (L3) of 18.24 mm, are critical parameters for correct installation and are detailed in the dimensional drawings within the catalog of mechanical seals.

**Performance Features and Application**
Classified with a seal grade of "E", the IN0150.E.BQPGG is designed for balanced performance in a variety of media. The bellows-type (сильфонное) design eliminates the need for a dynamic O-ring, reducing friction and hang-up, which is particularly advantageous in applications with crystallizing or viscous fluids. The combination of silicon carbide and graphite as the primary sealing faces ensures reliable operation with minimal leakage and heat generation. This mechanical seal is suitable for use in chemical processing, general industrial pumping, water treatment, and irrigation systems, where dependable sealing is paramount. The accurate dimensions of the mechanical seal are essential for ensuring a proper fit within the seal chamber and preventing premature failure.

**Selection and Compatibility**
When selecting a replacement or specifying a new seal, referencing the complete model code IN0150.E.BQPGG and verifying all key dimensions against the equipment specifications is crucial. This seal represents a standardized, high-quality component from the INE range, providing a cost-effective and reliable sealing solution. For correct identification and cross-referencing, always consult the relevant technical documentation and the catalog of mechanical seals to confirm all installation parameters, including shaft diameter, bore size, and working length.
