Which statement best describes the pump type commonly used as a booster pump in distribution systems?

• A. It is rarely used as a booster pump
• B. It is used only for irrigation
• C. It is commonly used as booster pumps in distribution systems
• D. It cannot be used as a booster pump

Answer: (C)

Boosting pressure in a distribution system relies on a pump that can deliver steady flow while creating enough head to overcome friction and elevation. Centrifugal pumps fit this role well; they provide a reliable range of flow with adjustable head (by changing speed or impeller size), and can be arranged in multiple stages to reach higher pressures needed in networks. This combination makes centrifugal pumps the standard choice for booster stations in water distributions. They’re not limited to irrigation and are indeed commonly used to maintain adequate pressure throughout the system.
