Centrifugal pumps are capable of evacuating (pumping) a modest amount of air from the suction side of the pump to the discharge side of the pump. Filling the inlet system with fluid or at least filling the pump (wetted pumping elements) will make a major improvement in the pump’s priming capability.

## Experiment #10: Pumps – Applied Fluid Mechanics Lab Manual

A centrifugal pump consists of a rotating shaft that is connected to an impeller, which is usually comprised of curved blades. The impeller rotates within its casing and sucks the fluid through the eye of the casing (point 1 in Figure 10.1). The fluid’s kinetic energy increases due to the energy added by the impeller and enters the discharge ...

Dry running is usually undesirable in a centrifugal pump; it occurs in the total absence of the liquid component of the fluid handled (e. g. following the ingress of air in the suction line) or if under normal operating conditions gas bubbles (see Formation of air pockets) attach themselves to normally wetted rotating components (partial dry running). During normal operation of a well-designed ...
