Manufactured from high-grade FCD450 Spheroidal Graphite Ductile Iron (high-chrome wear resistance), this replacement volute acts as the core hydraulic pressure chamber. It channels fluid and solids efficiently away from the impeller while providing maximum abrasion resistance against sand, slurry, and debris up to 1.5 inches (38 mm).
