  • What is a Volute? - Definition from Corrosionpedia

    2020-4-6 · A volute is a spiral-shaped pump casing frequently used in centrifugal pumps. The purpose of the volute is to convert the liquid's velocity to pressure as the impeller discharges the liquid through the casing nozzle. This is achieved via a gradually increasing cross-sectional area in the volute that increases the fluid’s flow-through area, thus ...
