What is one function of an impeller in a pump?

The function of an impeller in a pump is primarily to increase fluid pressure. An impeller is a rotating component that moves fluid through the pump by converting mechanical energy from the motor into kinetic energy. As the impeller turns, its blades push the fluid outward, which creates a difference in pressure that pulls more fluid into the pump and forces it out at a higher pressure. This design is crucial in systems where the movement of water or other liquids is necessary, such as in irrigation, heating systems, or drainage applications.

In contrast, generating electrical energy and filtering solids from liquids are roles carried out by different types of equipment and processes. While turbulence may be generated as a part of the fluid movement, it is not the primary function of the impeller but rather a byproduct of its operation. Thus, the function of increasing fluid pressure is key to the efficiency and effectiveness of a pump's operation.
