What type of pump is designed to be placed below the water level in a well?

• A. Jet pump
• B. Submersible pump
• C. Diaphragm pump
• D. Gear pump

Answer: (B)

A submersible pump is specifically designed to be placed underwater, such as in a well, where it can efficiently draw water from below the water level. This type of pump operates by being submerged in the fluid it is pumping, which helps to maintain its own priming. Being submerged allows the pump to push water to the surface using a hermetically sealed motor that is combined with the pump body. This design minimizes issues related to cavitation and allows for more effective operation at great depths. In comparison, a jet pump operates by creating a vacuum that draws water into the pump from above the water level, making it unsuitable for installation below the water surface. A diaphragm pump uses a flexible diaphragm to create a pumping action and is not intended for deep well applications. Similarly, a gear pump is designed for moving viscous fluids and typically functions best in an upright position, not submerged underwater. Thus, the design and function of a submersible pump make it the most appropriate choice for operation in wells where it is submerged below the water level.
