Submersible Materials Selection: Cast Iron vs Stainless vs Duplex in Wastewater

Introduction to Submersible Pump Metallurgy One of the most persistent and costly challenges in modern wastewater management is the premature degradation of submersible pumping equipment due to shifting influent chemistry. As water conservation efforts reduce flow rates, wastewater becomes more concentrated. Simultaneously, longer retention times in force mains and collection basins accelerate septicization, leading to […]
