Centrifugal pumps can discharge water from what minimum to maximum range of GPM?

Centrifugal pumps are designed to efficiently handle a wide range of flow rates, and the correct range for these pumps is indeed from 25 to 5000 gallons per minute (GPM). This range allows for versatility in various applications, from low flow scenarios in smaller systems to high flow needs in larger installations.

The lower limit of 25 GPM is practical for smaller systems where precise and moderate flow rates are required, making centrifugal pumps suitable for residential fire protection or irrigation systems. The upper limit of 5000 GPM represents the capability of these pumps to manage substantial volumes of water necessary for larger municipal, industrial, or irrigation systems.

Centrifugal pumps operate based on the principles of centrifugal force, allowing them to sustain efficient operations across this broad range of flow rates. This capability is a significant reason why they are widely utilized in both fire protection systems and other applications requiring reliable water movement.

The other ranges provided do not accurately represent the typical operational parameters for centrifugal pumps. Some are either too narrow or too broad compared to industry standards, emphasizing the wide applicability and flexibility inherent in the design and operation of centrifugal pumps.
