What is the function of a booster pump?

• A. To circulate water at normal pressure
• B. To take suction from one pump and discharge at a higher pressure
• C. To create vacuum conditions in piping
• D. To cool rotating equipment

Answer: (B)

The function of a booster pump is to take suction from one pump and discharge at a higher pressure. This device is specifically designed to increase the pressure of a fluid, allowing it to be delivered to areas requiring higher pressures or to overcome system limitations such as elevation changes or friction losses in the piping. Booster pumps are commonly used in various applications, including water supply and irrigation systems, where they ensure adequate pressure for proper flow.

In contrast to the other options, a booster pump does not just circulate water at normal pressure, create vacuum conditions, or cool rotating equipment. Instead, its primary job focuses on elevating the pressure of the liquid to meet specific operational needs within a system. This capability is crucial in ensuring that fluids reach their targeted locations effectively, especially in complex piping systems where pressure drops can occur.
