Mechanical Seal HE160A

The HE160A Mechanical Seal is a robust and versatile sealing solution engineered for precision and reliability in a wide variety of industrial fluid handling systems. Known for its superior construction and dependable performance, the HE160A is ideal for use in pumps, mixers, and rotating equipment across diverse sectors including chemical processing, petrochemical industries, food and beverage, pharmaceuticals, water treatment, and power generation.

This seal is designed with a single balanced, pusher-type configuration, which allows it to operate under varying pressure conditions while maintaining stability and minimal leakage. The balanced design significantly reduces the axial load on the seal faces, improving the seal’s longevity and reducing wear, even in high-pressure systems. Its pusher mechanism ensures consistent sealing even when faced with shaft movements, thermal expansion, or misalignments.

The HE160A typically uses high-grade materials for optimal performance and resistance. The seal faces are made from premium-grade materials such as Tungsten Carbide, Silicon Carbide, or Carbon, which provide excellent thermal and chemical resistance. These materials are highly durable and capable of withstanding abrasive and corrosive media. The secondary sealing elements are manufactured from elastomers like Viton, EPDM, or Nitrile (NBR), selected based on compatibility with the process fluid. The metal components are generally crafted from SS316 or SS304 stainless steel, offering mechanical strength and corrosion resistance.

One of the distinguishing features of the HE160A is its modular and compact design, which facilitates quick installation and easy maintenance without dismantling the equipment entirely. The mechanical seal is engineered to operate efficiently under a temperature range from -20°C to +180°C, making it suitable for both chilled and high-temperature processes. It can withstand pressures up to 20 bar and shaft speeds up to 3600 RPM, depending on the size and material configuration.

Available in shaft sizes ranging typically from 20 mm to 100 mm, the HE160A can be customized to fit specific application needs. The seal also offers excellent chemical compatibility, allowing it to handle aggressive chemicals, slurry, light hydrocarbons, and other industrial fluids. Its design accommodates minor shaft misalignment and vibration, ensuring consistent performance over long operating cycles.

The HE160A complies with DIN 24960 and ISO 3069 standards, ensuring compatibility with a wide range of pump brands and models. It is often used as a replacement or equivalent for well-known international sealing systems such as Burgmann M7N and John Crane Type 21 or 2100, making it a reliable alternative for OEM applications.

Maintenance professionals prefer the HE160A for its reliable sealing, low friction operation, and extended service intervals. Whether used in clean water systems or aggressive process media, this seal minimizes unplanned downtimes and reduces overall lifecycle costs.
