What is the name of the pump component that moves the fluid by imparting energy to it?

Explanation:
The impeller is the part that moves the fluid by imparting energy to it. It’s the rotating element with blades that receives mechanical energy from the motor and transfers it to the fluid, increasing its velocity and, as the flow moves through the pump casing, its pressure. The pump casing mainly guides and houses the flow and helps convert velocity to pressure but does not itself impart energy. A disk isn’t the energy-transfer component in a pump, and the packing gland is a seal that prevents leaks around the shaft.
