Centrifugal pumps have a wide range of applications where the pressure increase is caused by centrifugal forces.

Centrifugal pumps are turbomachines that pump liquids by means of centrifugal force generated by rotating impellers. Axially to the impeller, the liquid to be pumped enters the suction port of the pump on the suction side. The impeller rotating in the pump accelerates the liquid under the effect of centrifugal force.

The increase in speed raises the dynamic pressure in the fluid. When leaving the impeller, the liquid is slowed down again at the discharge port due to the accumulated liquid. Thus, the dynamic pressure of the liquid is converted into static pressure (more information about the relationship between dynamic and static pressure can be found in the article Venturi Effect). As a result, the static pressure at the discharge port increases very much. This high pressure enables the liquid to overcome a certain geodetic head.

Product Specification

In contrast to axial flow pumps, radial flow pumps can provide higher pressure heads, but they usually produce a relatively low flow rate. To achieve high flow rates, several radial flow pumps may have to be connected in parallel. Axial flow pumps offer high volumetric flow rates, but only relatively low pressure heads (approx. 15 m). In order to achieve large pressure heads with axial flow pumps, several pumps may have to be connected in series. A compromise between the advantages and disadvantages of both pump types is offered by mixed flow pumps.
