What is the function of a packing gland in a pump?

To increase fluid pressure
To prevent fluid leakage
To cool the pump
To measure fluid temperature

The correct answer is: To prevent fluid leakage

The function of a packing gland in a pump is to prevent fluid leakage. It plays a crucial role in sealing the shaft as it passes through the pump casing, which is necessary to maintain the integrity of the system and prevent the escape of the liquid being pumped. By using packing material that surrounds the shaft and is compressed by the gland, it creates a tight seal, minimizing the risk of leaks. This is particularly vital in applications where maintaining fluid containment is essential for operational efficiency and safety. In contrast, while increasing fluid pressure, cooling the pump, or measuring fluid temperature are important aspects of pump operation and management, they are not directly related to the specific function of a packing gland. These processes generally involve other components or systems within the pump infrastructure designed for those specific purposes.
