Enclosing the area between the impeller vanes reduces flow recirculation, which leads to a more efficient high-pressure output. While enclosed impellers are effective to increase pressure, they limit the solids-handling ability of the impeller. High-pressure pumps often have a strainer to prevent the enclosed impeller from clogging.
