A shallow-well jet pump and a deep-well jet pump are both used to draw water from wells, but they differ in their design and application based on the depth of the water source. A shallow-well jet pump is designed for wells where the water level is less than 25 feet deep. It is typically installed above ground and uses a single pipe to draw water. The pump creates a vacuum that lifts water to the surface. It relies on atmospheric pressure to push water into the pump, making it suitable for shallow depths. Shallow-well jet pumps are simpler in design and generally easier to install and maintain. In contrast, a deep-well jet pump is used for wells with water levels deeper than 25 feet, typically up to about 110 feet. This pump system involves two pipes: one for pushing water down into the well and another for lifting it back up. The pump is also installed above ground, but it uses a jet assembly located in the well to increase the pressure and lift water from greater depths. The jet assembly creates a venturi effect, which helps in lifting water efficiently from deeper sources. Deep-well jet pumps are more complex and may require more maintenance due to their additional components. In summary, the primary difference lies in their application based on well depth: shallow-well jet pumps are for depths less than 25 feet, using a single pipe system, while deep-well jet pumps are for greater depths, utilizing a two-pipe system with a jet assembly to lift water efficiently.

A convertible well jet pump is a type of water pump designed to draw water from wells. It is called "convertible" because it can be configured for either shallow well or deep well applications, depending on the installation setup. This adaptability is achieved by using different jet assemblies and nozzle configurations. In a shallow well setup, the pump is installed above ground, and the jet assembly is placed in the pump housing. This configuration is suitable for wells with a water depth of up to 25 feet. The pump creates a vacuum that draws water up through a single pipe. For deep well applications, the jet assembly is placed down in the well, and a two-pipe system is used. This setup allows the pump to draw water from depths of up to 90 feet. The first pipe sends water down to the jet assembly, where it is mixed with the well water and then pushed back up through the second pipe to the surface. Convertible well jet pumps are ideal for situations where the water table may fluctuate, or when the exact depth of the water source is uncertain. They offer flexibility and can be adjusted to suit changing conditions without needing to replace the entire pump system. These pumps are commonly used in residential, agricultural, and light commercial applications where a reliable water supply is needed from a well. In summary, a convertible well jet pump should be used when there is a need for flexibility in water depth, when the water source depth is uncertain, or when there is a possibility of needing to switch between shallow and deep well configurations.
