In relay pumping, what is the primary reason for positioning pumpers close together?

In relay pumping, the primary purpose of positioning pumpers close together is to effectively manage pressures that exceed what a single engine can supply. This strategy is essential in scenarios where the water needs to be transported over long distances or where high pressure is required for applications such as firefighting. By utilizing multiple pumps in close proximity, each pump can contribute to maintaining the necessary pressure in the system, thereby ensuring that adequate water flow is delivered to the destination.

This method enhances the overall efficiency of the pumping operation, as each pump can work collaboratively to achieve the desired output. It also allows for better coordination among pump operators, enabling them to monitor and adjust the operation quickly based on the pressures and flows being experienced. As a result, this arrangement plays a crucial role in meeting the operational demands in various pumping scenarios.
