This article is part of Pumps 101, an eleven-part series of articles designed as an introduction to the fundamentals of centrifugal pump design, selection, and application. To get the most out of Intro to Pumps check out the full series:The impeller of a centrifugal pump is rotated rapidly to impart velocity to a pumped liquid. If you’ve never seen a pump impeller before, visualize a boat propeller. When a boat propeller is rotated it imparts velocity to the liquid around it. As the liquid moves, that velocity forces the propeller to move . See more
