A centrifugal pump involves a high speed rotating impeller transmitting kinetic energy to processed fluid. Radial pumps gets fluid direction changed often by 90° angle from intake while inline pump can exists as well. This speed may be converted latter into fluid pressure while it exits the pump in the discharge pipe.

Such pumps are mainly used in industrial processes and often driven by mechanical_driver=electric_motor and direct coupling.

	Africa	man_made=water_well pump_mechanism=centrifugal mechanical_driver=electric_motor	A standard electric submersible pump with electric motor to power a multi-stage centrifugal impeller. Intake is located on the pump body side and centrifuguation makes the water go out on top.

	France	man_made=pump pump_mechanism=centrifugal mechanical_driver=electric_motor (optional mechanical_coupling=direct)	A common radial centrifugal_pump driven by an electric motor in a drinkable water production facility
	The Netherlands	man_made=pump pump_mechanism=centrifugal mechanical_driver=electric_motor (optional mechanical_coupling=direct)	A common radial centrifugal_pump driven by an electric motor probably used for irrigation or water reservoir feeding
	-	man_made=pump pump_mechanism=centrifugal mechanical_driver=electric_motor (optional mechanical_coupling=direct)	An inline centrifugal_pump driven by an electric motor. Centrifugal pumps can sometimes find inline, with less axial efforts than radial ones.
	France	man_made=pump pump_mechanism=centrifugal mechanical_driver=electric_motor mechanical_coupling=belt	This example focus on coupling an electric motor to centrifugal pump with a belt. Both pump and motor are behind the blue casing

Here is how this example is evaluated: Kreislpumpe means it's a centrifugal pump H=65.3 m means the pump raises the liquid level at 65.3 meters which is equivalent to 6.53 bar for pressure=* Q=26.2 m3/h means the pump is able to deliver 26.2 m3 in one hour which is equivalent to 7.3 litre per second for flow_rate=*

	Switzerland	man_made=pump pump_mechanism=centrifugal mechanical_driver=electric_motor (optional mechanical_coupling=direct)	Hydropower generation sometimes involves pump for large scale water storage. Some power plants have pumps separated from turbines like in Veytaux, Switzerland where a 600 tons multi-stage centrifugal pump is located below a Pelton turbine, linked by a direct coupling (see this chart). The pump is driven by the generator used as an electric motor with electricity coming from transmission grid. When the pump s running, the Pelton turbine runs empty without water.
