The centrifugal pump operates based on the outward force generated by the rotation of a central impeller. As the impeller spins, it imparts kinetic energy to the fluid, which causes the fluid to move from the center of the pump towards the outer edges. This movement is a result of centrifugal force, which pushes the fluid outward as it is spun around the rotational axis.

In a centrifugal pump, the design typically includes an enclosed casing that helps direct the flow of the fluid and maintain pressure. This operation allows centrifugal pumps to achieve high flow rates and efficient performance for a variety of applications, making them commonly used in firefighting and other industrial processes.

Other types of pumps, such as positive-displacement pumps or rotary vane pumps, operate using entirely different principles. They rely on mechanisms that physically displace fluid volume, rather than using rotational force to create flow. This fundamental difference in operation is what distinguishes the centrifugal pump as the correct choice for this question.
