Jet Pump Working Principle
- Construction Fig. shows an arrangement of a jet pump in a bore well.
- Each jet pump consists of a conventional radial flow pump with a jet nozzle at the suction end.
- This helps to increase suction lifts beyond the normal limit of about 8 m of water head.
- With the use of the jet assembly, it is possible to increase the suction lift to 60 m.

Working This working operation from the jet pump is as follows
- The suction side is filled with water also the pump is started.
- Some stream of high-pressure water from a specific delivery pipe of the pump remains allowed to flow through that suction jet nozzle. Some pressure energy of water is converted into kinetic energy due to which a local drop-in this pressure takes place. Due to this pressure drop suction remains created including water being sucked from the bore well. Here action ensures a considerably large supply of low-pressure water.
- During the streams with different velocities mix (in this mixing zone), some pressure rise takes place in some mixing zone.
- Behind the mixing zone, there is a diverging section where the further rise of pressure occurs due to a decrease in velocity.
Uses The fields of the jet pump are
- A jet pump can be used to take out muddy water from excavation trenches
- To lift water from wells of smaller bores
- Employed in mining also for pumping oil
