How does underwater pumps well?

Underwater pumps, often referred to as submersible pumps, work by being submerged in the fluid they are designed to pump. They use an electric motor that is sealed within the pump casing to drive an impeller, which creates a pressure differential that moves the fluid through the pump and up to the surface. These pumps are efficient for moving groundwater or other liquids from deep wells, as they are capable of generating high pressure and can operate continuously without losing prime. Their design minimizes the risk of cavitation and allows for better cooling of the motor compared to surface pumps.
