n: a specialised form of hydraulic pump, used in artificial lift. whose main working parts are nozzle, throat, and diffuser. The nozzle converts the highpressure, low-velocity energy of the power fluid to high-velocity, low-pressure energy. The power fluid is then mixed with the lowpressure pump intake fluid in the throat to produce a low-pressure stream with a velocity less than that of the nozzle exit, but a high velocity, nevertheless. The velocity energy of this mixed stream is then converted to static pressure in the diffuser to provide the pressure necessary to lift fluid from the well. The power fluid may be either oil or water.
