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.

n: a pump that operates by means of a jet of steam, water, or other fluid that imparts motion and subsequent pressure to a fluid medium.

an artificial lift device that uses the flow of a power fluid through a nozzle to create a low pressure area that draws well fluids into the chamber and assists in lift the fluids to the surface.

n: a device that increases the pressure on a fluid or raises it to a higher level. Various types of pumps include the bottom- hole pump, centrifugal pump, hydraulic pump, jet pump, mud pump, reciprocating pump, rotary pump, sucker rod pump, and submersible pump.
