2018年2月19日 · A pump curve denotes flow on the x-axis (horizontal) and head pressure on the y-axis (vertical). The curve begins at the point of zero flow, or shutoff head, and gradually descends until it reaches the pump runout point or maximum flow rate.
A pump curve is a graphical representation of the performance characteristics of a pump. A pump curve provides a wealth of information regarding the performance capabilities of a pump. Information is plotted on an x-y graph where the x-axis is measured in units of flow and the y-axis is measured in units of head, power, and NPSHr.
2022年5月26日 · Pump performance curves give you the information you need to choose the right pump for your application. In this comprehensive pumps article, you will receive a pump curve explanation, learn how to plot a pump curve, and learn how to compare pump curves for selecting the right pump for the job.
A pump performance curve is also known as a pump efficiency curve, pump selection curve, pump characteristic curve, or simply a pump curve. The pump performance curve is the design analysis (or indication) of the pump and how it will operate with respect to the changes in operating parameters such as Pressure (Pressure Head is derived from ...
The pump performance curve describes the relation between the flowrate and the head for the actual pump. Other important information for a proper pump selection is also included - like efficiency curves, NPSH r curve, pump curves for several impeller diameters and different speeds, and power consumption.
2018年9月24日 · Centrifugal Pump curves show 8 important factors that are critical in selecting the right pump for your application. These factors are: Flow, Head, Impeller Trim Diameter, Efficiency, Power, NPSHR, MCSF (Minimum Continuous Stable Flow) and RPM.
In simple terms, a pump curve is a graphical representation of the performance of a pump. It provides you with information of several elements of a pump’s performance, helping you identify and select the right pump for your needs.
