In myriad industrial settings, fluids have to do more than lie idle in a reservoir. We put fluids to work throughout systems, and in order to get them moving, we rely on pumps to get the ball—or more accurately the water, or the solvent, or the slurry—rolling. When dealing with low-viscosity fluids that offer little resistance, a centrifugal pump is often the best variant for sending them through process piping and other systems. Unlike other models, centrifugal pumps use rotational energy to circulate their fluids. Within this broad category are several different types of centrifugal pumps, a few of which we’ll examine here.
