Polished SS304 HE92-42 Mechanical Seal, Color : Silver, Black

The HE92-42 Mechanical Seal is a precision-engineered, high-performance mechanical seal specifically designed for use in pumps, agitators, and rotating equipment operating under demanding industrial conditions. Known for its rugged construction and long service life, this seal is particularly suited for applications in the chemical, petrochemical, pharmaceutical, water treatment, and food processing industries.

The HE92-42 is a single, balanced, pusher-type mechanical seal, which allows it to handle moderate to high pressures while maintaining excellent sealing performance. The balanced design minimizes face load and reduces friction between seal faces, resulting in lower heat generation and increased durability. It is engineered to accommodate axial shaft movements and moderate misalignments, offering operational flexibility across various equipment setups.

The seal faces of the HE92-42 are available in high-grade materials such as Silicon Carbide (SiC), Tungsten Carbide (TC), or Resin-impregnated Carbon, selected based on fluid compatibility, process requirements, and desired thermal performance. These materials provide excellent resistance to wear, corrosion, and thermal stress, ensuring reliability in both corrosive and abrasive media.

The secondary sealing components, including O-rings and gaskets, are made from premium elastomers such as Viton, EPDM, or Nitrile (NBR). These materials are chosen for their chemical compatibility, resilience, and ability to function across a wide temperature spectrum. The metallic components, including the springs and gland rings, are typically manufactured using stainless steel grades SS304 or SS316, offering superior strength and corrosion resistance in harsh environments.

The HE92-42 Mechanical Seal is capable of operating at pressures up to 20 bar and shaft speeds of up to 3600 RPM. It is also engineered to function within a broad temperature range from -20°C to +180°C, making it suitable for both cold and high-temperature fluids. This makes the seal ideal for handling acids, bases, oils, solvents, light slurries, and water, among other process fluids.

This seal conforms to DIN 24960 and ISO 3069 standards, ensuring compatibility with a wide range of pump brands and types. Its modular, compact construction allows for easy installation, replacement, and maintenance, reducing downtime and ensuring continued productivity in industrial environments.

Applications for the HE92-42 Mechanical Seal include its use in centrifugal pumps, vacuum pumps, agitators, compressors, and other rotating process equipment. Due to its versatile design and material flexibility, it is often the seal of choice for operators looking to standardize across multiple systems while maintaining high sealing performance.

In conclusion, the HE92-42 Mechanical Seal delivers dependable sealing under varying operational conditions, with optimized material selection and design engineering for durability, efficiency, and chemical resistance. Whether in continuous or batch processing environments, it helps reduce leakage, lower maintenance costs, and extend the lifespan of the machinery it serves.
