HE160 Mechanical Seal

The HE160 Mechanical Seal is a high-performance, balanced pusher-type seal designed for demanding industrial applications involving a variety of fluids under challenging operating conditions. As part of the HE series, the HE160 combines durability, versatility, and precise engineering to offer a dependable sealing solution for pumps, mixers, and other rotating equipment used across industries like chemical processing, petrochemical, water treatment, pulp and paper, food and beverage, and pharmaceuticals.

Constructed with superior-grade materials, the HE160 Mechanical Seal is known for its resistance to wear, corrosion, and high temperatures. The seal faces are commonly manufactured from premium Silicon Carbide (SiC), Tungsten Carbide (TC), or Resin-impregnated Carbon, depending on the application's specific fluid compatibility and operating parameters. These materials offer excellent surface hardness and low friction coefficients, allowing for extended service life even in abrasive or chemically aggressive media.

The secondary sealing components, such as O-rings or gaskets, are made from elastomers like Viton, EPDM, or Nitrile (NBR), offering resistance to a wide range of chemicals and temperature extremes. The metallic parts, typically SS304 or SS316 stainless steel, provide strength, corrosion resistance, and structural stability. This blend of materials makes the HE160 a go-to solution for both standard and hazardous fluid systems.

A key design feature of the HE160 is its balanced mechanical configuration, which reduces axial loading on the seal faces and minimizes distortion under pressure. This allows the seal to perform reliably at pressures of up to 20 bar and shaft speeds of up to 3600 RPM. The balanced nature also reduces heat generation, preventing premature wear and leakage. Additionally, the pusher design accommodates axial shaft movement and thermal expansion, ensuring continuous sealing performance even under fluctuating load and temperature conditions.

With a typical operating temperature range from -20°C to +180°C, the HE160 is well-suited for both chilled and high-temperature process environments. It is available in a range of shaft sizes, generally from 20 mm to 100 mm, and can be custom-adapted to suit specific equipment or installation needs. The seal’s modular structure and standard compliance (DIN 24960 / ISO 3069) ensure compatibility with most industrial pump types and ease of replacement.

Thanks to its rugged construction, the HE160 is especially suited for handling corrosive chemicals, light slurries, hydrocarbon-based fluids, water, and various organic compounds. It is often used in centrifugal pumps, end-suction pumps, and vertical in-line pumps where sealing integrity is critical to plant safety and uptime.

In practical terms, the HE160 Mechanical Seal is favored for its easy installation, low maintenance needs, and long operational life. It offers a significant return on investment by reducing downtime, leakage, and equipment wear caused by inferior sealing systems.

In summary, the HE160 Mechanical Seal stands out for its engineering precision, material resilience, and operational flexibility. Whether used in high-pressure chemical systems or general-purpose industrial pumps, it consistently delivers robust sealing performance, helping industries maintain safety, efficiency, and reliability in their fluid-handling operations.
