Goulds 3175S 2-Vane Impeller 17.5" Diameter 316SS

The Goulds 3175S 2-vane impeller is a critical component designed for the Goulds 3175S series centrifugal pumps, commonly used in pulp and paper, wastewater, and slurry handling applications. This semi-open impeller features a 17.5-inch diameter and is constructed from durable 316 stainless steel, providing excellent corrosion resistance and strength for handling abrasive solids and high-viscosity fluids. Its 2-vane design allows for efficient passage of large particles up to several inches in diameter, reducing clogging and improving pump performance in demanding environments. Key benefits include enhanced efficiency in stock pumping, lower maintenance needs due to robust materials, and compatibility with pump sizes 4x6 and 4x10-18. Compared to standard multi-vane impellers, this model offers superior solids-handling capability but may have slightly lower efficiency in clear liquids. Drawbacks include potential for higher wear in extremely abrasive conditions without proper maintenance. Based on attached images, the impeller appears to be in used condition with minor surface wear, green paint residues, and some scratches, but structurally intact with no major damage. It includes a protective orange cap on the hub. Serial/markings include '257-102', '1203', 'WCM 55930'. Manufactured in 1994, this part is suitable for refurbishment or direct replacement.
