The pump is powered by an electric motor that drives an impeller, or centrifugalpump. The impeller moves water, called drive water, from the well through a narrow orifice, or jet, mounted in the housing in front of the impeller. … Its function is to slow down the water and increase the pressure.
A booster pump is a machine which will increase the pressure of a fluid. … A gasbooster is similar to a gas compressor, but generally a simpler mechanism which often has only a single stage of compression, and is used to increase pressure of a gas already above ambient pressure.
What is the pumping process?
Optical pumping is a process in which light is used to raise (or “pump“) electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction, to pump the active laser medium so as to achieve population inversion.
