What is often the objective in series pump applications?

In series pump applications, the primary objective is to produce higher heads without the need for adding additional stages. When pumps are arranged in series, the output of one pump feeds directly into the next, allowing the pressure (or head) produced by each pump to be additive. This configuration is particularly advantageous in scenarios where the system requires elevated pressure to overcome system head losses, such as in high-rise buildings or extensive irrigation systems.

By utilizing a series arrangement, a designer can effectively increase the total head produced by the combined pumps, providing the necessary pressure to facilitate the movement of fluids to greater heights or through longer piping distances while maintaining the same flow rate. This approach is efficient in enhancing system performance while also maintaining simplicity in achieving desired pressure levels, as opposed to having multiple pump stages within a single pump unit, which would complicate maintenance and operational considerations.

The other options, while they may have relevance in certain contexts, do not encapsulate the primary intent of series pumping as effectively as the objective of achieving higher heads.
