Jet pumps are capable of handling all forms of motive fluid including gas, steam, or liquid. They are typically inserted vertically into the process media, but can be mounted horizontally as well. Multiple inlets are used to draw in a constant stream of fluid, using pressure to create lift through suction. The combination of intake pressure and velocity of the liquid or gas jets the media up from a well, tank, or pit through the pump to the discharge point. There are basically four main types of jet pumps; deep well, shallow well, convertible, multi-stage, and mini. Deep well jet pumps are used in high volume applications, such as oil wells, which range from 800-15,000 feet in depth. Shallow well pumps are used in applications where the media is close to the surface, such as residential wells. Convertible jet pumps can be used for either deep or shallow well applications. Miniature jet pumps are used for smaller applications, such as aquariums.
