INTRODUCTION One of the most persistent errors in municipal and industrial fluid handling involves applying centrifugal pump logic to positive displacement equipment. Engineers often approach pump curves expecting a single line intersecting a system curve, but when faced with an Air-Operated Double Diaphragm (AODD) performance chart, they encounter a complex grid of air pressures, air […]

Introduction In high-volume municipal flood control, stormwater management, and industrial water transport, the axial flow “propeller” pump is the workhorse of the hydraulic world. However, their unique specific speed characteristics and sensitivity to intake conditions make them prone to issues that differ significantly from standard centrifugal pumps. Engineers and operators frequently overlook the subtle precursors […]
