What type of fire pumps are usually used in these systems?

• A. Positive displacement type
• B. Centrifugal type
• C. Diaphragm type
• D. Jet pumps

Answer: (B)

The centrifugal type of fire pumps is typically used in standpipe systems due to their ability to efficiently handle large volumes of water at relatively low pressures, which aligns well with the requirements of fire protection systems. Centrifugal pumps operate by converting rotational energy, usually from an electric motor or engine, into hydrodynamic energy, allowing them to move water effectively through the piping system. These pumps are favored in standpipe systems because they can provide a consistent and reliable supply of water, which is crucial in firefighting situations. Their design allows for ease of maintenance and operation, making them suitable for the sustained use that may be required during a fire emergency. In contrast, positive displacement pumps are generally used for higher pressure applications with lower flow rates and are not as commonly found in standpipe applications. Diaphragm pumps, while useful in certain scenarios, do not provide the same volume output required for standpipe systems. Jet pumps are typically utilized in applications that require lifting water from a source rather than supplying high volumes to a sprinkler system. Therefore, the centrifugal type stands out as the most appropriate choice for the demands of standpipe systems.
