3 Centrifugal Pump Impellers and what they are used for

As the impeller rotates, it pulls liquid in at the center, or eye, of the impeller, and the spinning vanes create the centrifugal force that pushes the liquid to the outside of the pump casing, and ultimately out the discharge port. There are three basic impeller designs. Closed Impellers. Semi-open Impellers. Open Impellers.

Open Impeller - an overview ScienceDirect Topics

With semi-open designs, provisions can be made in the mechanical design to readjust its setting gap, sometimes even when the pump is running! Hence any efficiency decay can, up to a point, be reversed. But semi open impellers also have some negative points relative to closed impellers. The chief concern is of unbalanced hydraulic axial load.
