What is the process of filling a pump casing with water to remove air called?

• A. Priming
• B. Overpumping
• C. Draw Down
• D. Cavitation

Answer: (A)

Priming is the process of filling a pump casing with water to remove air, ensuring that the pump can operate effectively. When a pump is initially started or when it has run dry for any reason, air pockets can form in the casing, which can prevent the pump from drawing water properly. By priming, the pump casing is filled with water, allowing for an uninterrupted flow and preventing damage to the pump that could occur from running without water. This process is crucial for maintaining the efficiency and longevity of the pumping system. In contrast, overpumping refers to the scenario where the amount of water being extracted exceeds the sustainable yield of the source, potentially leading to issues such as depletion of the water supply. Draw down describes the lowering of the groundwater level in a well due to the extraction of water, which is a separate concept entirely. Cavitation is a phenomenon where vapor bubbles form in a liquid and collapse, potentially causing damage to the pump; this can occur if a pump is experiencing improper suction, but it is not related to the filling process of the pump itself. Thus, priming is the specific action required to ensure the proper functioning of the pump by avoiding the presence of air.
