Centrifugal pumps use centrifugal force to move fluid through a pumping system. They feature a rotating impeller that draws fluid into the pump's centre and propels it outwards, transferring energy to the fluid.
Types of centrifugal pumps include end-suction, normalised, peripheral, multistage, and submersible pumps, among others. They are widely used in water treatment, agriculture, oil and gas, and construction industries. Applications range from water supply and irrigation to spraying, dewatering, liquid and fuel transfer and chemical processing.
Centrifugal pumps can also be categorised based on their priming capability: self-priming and non-self-priming. After initial priming, self-priming pumps can start up with air in the system, making them ideal for applications where there's a possibility of air entering the suction line or where fluid needs to be drawn from below the level of the pump. Non-self-priming pumps require a fully flooded suction line as they cannot expel air from the system on their own.
