Introduction One of the most expensive misunderstandings in wastewater treatment and industrial fluid handling is the assumption that all pumps behave hydraulically like centrifugal pumps. This misconception is particularly dangerous when applied to positive displacement (PD) technology. While a centrifugal pump simply stops flowing when discharge pressure equals its shutoff head, a progressive cavity (PC) […]

Introduction Cavitation remains one of the most destructive forces in municipal and industrial fluid handling, capable of destroying impellers, ruining mechanical seals, and fracturing piping within weeks of operation. A surprising industry statistic suggests that nearly 30% of centrifugal pumps in wastewater applications operate outside their Preferred Operating Region (POR), leading to micro-cavitation that often […]

Introduction In municipal water distribution and industrial fluid handling, the management of reservoir and tank levels is a critical operational requirement. The altitude valve serves as the primary mechanical safeguard against overflows and the central mechanism for maintaining the hydraulic grade line within a specific pressure zone. These valves are specialized automatic control valves (ACVs) […]
