End Suction Cast 316 Stainless Steel
The End Suction Cast Iron Stainless Fitted pump is a durable and cost-effective solution engineered to balance economy with enhanced performance for challenging fluids. This design features a robust cast iron casing and structural components for strength and cost efficiency, while incorporating critical wear parts—such as the impeller, wear ring, and shaft sleeve—manufactured from stainless steel. This hybrid construction leverages the structural benefits and vibration-damping properties of cast iron, while the stainless steel fitted components provide superior resistance to corrosion, erosion, and abrasion at the key points of fluid contact and mechanical wear.
This configuration is ideally suited for applications involving slightly aggressive, brackish, or mildly abrasive liquids where a fully stainless steel pump may be cost-prohibitive. Commonly used in industrial water treatment, cooling tower service, certain chemical transfer, and general plant utilities, these pumps deliver extended service life and reduced maintenance over standard all-cast-iron models. They offer a practical, value-engineered solution that maintains reliability and performance in moderate-duty corrosive or erosive environments without the premium cost of an all-stainless construction.
