A jet pump is a type of pump that uses a jet of fluid to create a vacuum, which helps to lift water or other liquids from a lower level to a higher one. It operates by forcing a high-pressure fluid through a nozzle, creating a low-pressure area that draws in the surrounding liquid. This makes jet pumps effective for applications like well water extraction and irrigation systems. These pumps are often used in situations where traditional pumps may struggle, such as in deep wells or when dealing with low water levels. They are typically powered by an electric motor and can be found in both residential and industrial settings, providing a reliable solution for moving liquids efficiently.
