Which pump is commonly used as a booster pump in a water distribution system?

• A. Gear pump
• B. Diaphragm pump
• C. Centrifugal end-suction pump
• D. Vertical turbine pump

Answer: (D)

A booster pump needs to deliver high head with reliable, steady flow to raise pressure throughout the system, especially when water is coming from a depth or when space is limited. A vertical turbine pump is well suited for this role because its design stacks multiple impeller stages on a vertical shaft, allowing you to achieve a high total head by adding stages as needed. It’s commonly installed where water is drawn from a well or a lower intake and then discharged into the distribution system, making it a practical choice for boosting pressure in many distribution setups. The vertical arrangement minimizes floor space and allows the pump to be positioned close to the water source, which helps with efficiency and reliability at high head. In contrast, gear and diaphragm pumps are positive-displacement types that are more appropriate for small flows or specialized liquids and aren’t typically used for large-volume potable water boosting. End-suction centrifugal pumps are versatile and widely used in booster stations, but when the system requires high head from a deep source or compact, vertical installation, the vertical turbine design is especially advantageous due to its ability to supply high pressure in a robust, scalable way.
