Flygt (Xylem) Sewage Pump Special Mechanical Seal FS-25/35/45/60/90

Mechanical seals for wastewater pumps from Flygt (Xylem) are key components designed to cope with severe wastewater treatment environments, and their reliability and durability have a direct impact on the operational efficiency and maintenance costs of the entire pumping system. Through its double seal structure, high-quality wear and corrosion-resistant materials, innovative and patented technologies (such as the ActivSeal system) and user-friendly maintenance design, it excels in sealing reliability, service life and adaptability to harsh working conditions.

In response to the complex composition of sewage water, the friction parts (dynamic and static rings) of the mechanical seals for sewage pumps from Flygt (Xylem) are made of high-performance materials such as silicon carbide (SiC) or tungsten carbide (WCCR). These materials have extremely high hardness and excellent wear resistance, and can easily cope with fine solid particles in the medium. Meanwhile, its unique shaft seal design (such as the Flygt Griplock™ sealing system) can firmly lock the seal onto the shaft, avoiding possible shaft damage caused by rubber friction or top wire, further enhancing reliability, and making it an ideal choice for safeguarding the long-lasting and stable operation of wastewater treatment equipment.

Flygt (Xylem)  special mechanical seals combine excellent wear resistance and corrosion resistance. The dynamic and static rings are made of extremely hard silicon carbide or cemented carbide, which can effectively resist the abrasion of solid particles in sewage and the erosion of chemical media. Optimized bellows design eliminates the risk of clogging and ensures long sealing life and operational reliability under frequent start-stop and pressure fluctuation conditions.

All metal components are made of high-quality stainless steel and undergo strict surface passivation treatment, which significantly improves the durability in wet and corrosive environments and guarantees the intrinsic quality and consistency of the product.

The product adopts compact unitized design with high integration, easy and quick installation and replacement. Its unique balanced structural design can effectively balance the pressure in the sealing chamber and reduce the load on the end face, thus maintaining excellent sealing performance under high-pressure environments.

Adopting the spring static design, the spring is not in contact with the medium, effectively avoiding the spring jamming, blockage or corrosion caused by particles or crystals in the medium, and enhancing the reliability of the seal in the operation of the harsh media.
