A borehole pump is a type of water pump specifically designed to extract water from deep underground sources, such as aquifers. These pumps are typically installed in narrow, vertical wells, known as boreholes, and are used in various applications, including agricultural irrigation, drinking water supply, and industrial processes. Borehole pumps can be submersible or surface-mounted, with submersible pumps being placed directly in the water. They operate by creating a pressure difference that allows water to flow to the surface. Common types of borehole pumps include centrifugal pumps and positive displacement pumps, each suited for different depths and water conditions.
