Pump where the increase in energy associated with a medium is largely dependent on the kinetic energy applied to it. For flow rate and pressure, it is a case of:
where D = profile diameter,
u = circumferential velocity.
The flow rate is at its highest when the opposing pressure (load pressure) is zero and reduces to zero when the opposing pressure starts to exceed the kinematic pressure.
Centrifugal pumps are sometimes used in hydraulics as supply pumps.
