Centrifugal pumps with a single impeller, or set of curved vanes that push the water, are suitable for household, industrial, and civil applications, depending on the size of the pump and the motor.
The electric motor spins the impeller and through centrifugal force, the water is flung to the outside of the pump housing and out the outlet with more pressure than it entered the inlet. An easy way to imagine this is the effect of water flicking off a car tyre on a wet road.
Centrifugal pumps have low maintenance costs and are simple to
operate.
These pumps can only operate when the pump housing is filled with
water and should therefore always be installed lower than the water source, such as a tank.
