Centrifugal pump - Wikipedia

Most centrifugal pumps are not self-priming. In other words, the pump casing must be filled with liquid before the pump is started, or the pump will not be able to function. If the pump casing becomes filled with vapors or gases, the pump impeller becomes gas-bound and incapable of pumping. To ensure that a centrifugal pump remains primed and does not become gas-bound, most centrifugal pumps are located below the level of the source from which the pump is to take its suction. The same effect can be gaine…

Semi-Open Impeller - saVRee

Introduction. Semi-open impellers (sometimes called ‘partially open‘, or, ‘semi-closed‘) are utilized within radial flow centrifugal pumps.Unlike open impellers and closed impellers, semi-open impellers have only one shroud, which is mounted on the front or back of the impeller.This type of impeller is very well suited to handling liquids with a moderate amount of suspended bodies.

Impeller - Wikipedia

An impeller is a rotating component of a centrifugal pump which transfers energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation. The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing.
