Overview Series on the Harm and Benefits of Cavitation Processes in Engineering — What Causes Cavitation in Overhung Industrial Centrifugal Pumps, Why It's Dangerous, and How to Prevent It An overhung centrifugal pump is one of the most common types of industrial equipment: water supply, heating, chemical production, the food industry, irrigation. The simplicity of its design — an impeller mounted on an overhung shaft, installed in a volute casing — makes such a pump reliable and low-maintenance. But this very simplicity is often what fails: disturb the conditions on the suction side, and a pump that just moments ago ran quietly and smoothly begins to "fire" with a characteristic crackling noise, lose performance, and deteriorate from within. The cause is cavitation — a phenomenon we have already written about in relation to truck engines and the hydraulic systems of special machinery. In pumps it manifests in its own specific way, and this specificity is the subject of the third arti Less
