Everything about Impeller
Rotor that increases fluid pressure and flow
An impeller, or impellor, is a driven rotor used to increase the pressure and flow of a fluid. It is the opposite of a turbine, which extracts energy from, and reduces the pressure of, a flowing fluid. Wikipedia →

📖 Definitions
Noun Something which or someone who impels. A rotating component of a device that accelerates fluid, increasing its pressure or flowrate.
Noun A rotating component of a device that accelerates fluid, increasing its pressure or flowrate.
Noun Especially, such a component that drives the fluid radially (outward from a center of rotation) rather than axially. (Impellers are found in devices such as pumps, water jets, washing machines, and agitated tanks.)
