How to Choose the Right Impeller Dean Group International
Performance tests with the same pump casing volute (figure 1) show that an identical impeller to the open impeller but with a shroud on the suction side of the impeller increases the efficiency of the pump by as much as 5.3. In this design, the liquid follows a path down a tunnel formed on the sides by the vanes and is “closed” in on the top and bottom (or front and back depending on shaft orientation) by two shrouds. Closed impellers are mainly used for large pumps, for the application of handling suspended solid service. Radial flow impellers are normally provided with a front shroud and back shroud being called closed type.
