What is a series of graphs that provides information about the output characteristics of a pump?

A pump curve is a graphical representation that illustrates the performance characteristics of a pump as it operates under varying conditions. It typically plots flow rate on the horizontal axis versus head (or pressure) on the vertical axis, enabling users to assess how the pump will perform at different flow rates.

This curve is crucial for engineers and technicians since it helps determine the operational limits of the pump, including factors like efficiency, power consumption, and the necessary horsepower for specific applications. Selecting the right pump involves comparing its curve to the system curve of the hydraulic system it will serve, allowing for optimized performance and energy efficiency.

The other options, while they may sound relevant to pump performance, do not specifically describe the series of graphs that convey output characteristics. A pump report may include various performance metrics and insights, but it doesn't inherently consist of the graphical representation that a pump curve provides. Likewise, a pump chart could refer to numerous types of information around pumps but is not specifically defined as the set of graphs detailing output characteristics. Finally, pump analysis generally refers to the process of examining pump performance but does not denote the specific graphical output used to illustrate that performance.
