The jet pump is typically not suitable for deep wells due to its operational design, which relies on creating a vacuum to lift water from underground sources. Jet pumps use suction to draw water, and as the depth of the well increases, the efficiency of suction diminishes significantly. This makes it difficult for the pump to effectively lift water from deep depths, as the pressure drop becomes too great to overcome.

In contrast, submersible pumps are specifically designed to operate deeper in the water column by being placed directly in the well. They can push water to the surface without the limitations of suction. Diaphragm pumps and reciprocating pumps can also handle a variety of applications, including deeper wells, depending on their construction and operational limits. Thus, while jet pumps are effective for shallower applications, their performance markedly decreases in deep well scenarios.
