The Large Reaction Bonded Silicon Carbide (RBSC / SiSiC) Volute Liner is a critical wetted component designed for slurry pumps, FGD pumps, and other heavy-duty industrial pumping systems. Manufactured using advanced reaction-bonded silicon carbide technology, the volute liner offers exceptional wear resistance, corrosion resistance, and mechanical strength under the most demanding operating conditions.
Its optimized volute geometry ensures efficient fluid flow, reduced turbulence, and improved hydraulic performance, making it an ideal solution for abrasive and corrosive media handling.
Reaction bonded silicon carbide possesses extremely high hardness, providing excellent protection against abrasion caused by slurry, tailings, ash, coal slurry, and other solid-laden fluids.
Highly resistant to acids, alkalis, salts, and various chemical solutions, ensuring reliable performance in aggressive environments.
Precision-manufactured flow passages with smooth internal surfaces reduce friction losses and improve pump efficiency.
Maintains excellent mechanical properties at temperatures up to 1380°C, suitable for high-temperature industrial applications.
With a density significantly lower than steel and cast iron, the component reduces equipment weight and operating loads.
Compared with conventional metal volutes, RBSC volute liners offer substantially longer operating life, reducing downtime and maintenance costs.
