Net Zero Sealing - Process Side Components are Silicon Carbide or Tungsten Carbide

To meet the growing trends of carbon reduction and carbon neutrality, Scenic proudly introduces the all-new CarLife^® series single cartridge seal, CarLife^®79™ (CL79). 

This cutting-edge pump seal revolutionizes traditional corrosion-resistant materials like Hastelloy C (C-276), Hastelloy B, zirconium, titanium by replacing them with high-performance silicon carbide throughout all components in the wet process side. The seamless integration of a unique structural design and silicon carbide material showcases our unwavering commitment to innovation.

Applications for acidic, caustic, corrosive, and abrasive processes

The decision to utilize silicon carbide as the material for the process side stems from its unparalleled attributes, surpassing traditional corrosion-resistant materials in high-temperature resistance, corrosion resistance, erosion resistance, and abrasion resistance. As a result, CarLife^®79™ becomes the preferred choice for demanding applications such as high-corrosion pumps and scenarios with high levels of mineral impurities, ensuring extended service life and exceptional performance and durability. Additionally, the production of silicon carbide materials significantly reduces carbon footprint compared to rare metals, minimizing the energy consumption associated with mineral extraction and refining.

As the latest addition to our lineup, CarLife^®79™encapsulates Scenic's design prowess and innovative spirit, delivering superior performance and remarkable environmental benefits. Not only does this mechanical seal align with the prevailing materials application trends, but it also exemplifies our unwavering ambition and dedication to making a positive impact.
