How To Read Centrifugal Pump Curves Youtube 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. for the sake of example, today we’re going to look at a selection made for the following design. It is the minimum amount of pressure required at the pump suction in order for the pump to operate correctly. figure 2 represents the pressure drop that occurs between the suction and the impeller of two pumps. note that the lower curve dips below vapor pressure. this pump will surely cavitate, while the other is a suitable range above the npshr.
How To Read A Pump Curve Part 2 A pump curve shows the two performance factors on the x,y axis so you can see the volume of fluids a pump can transfer under various pressure conditions. this pump curve explanation also discusses variables such as: rpm. impeller size, as they related to pump performance. power. 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. the pump’s operating “sweet spot,” or best efficiency point (bep), is generally located near the. Pump size number. the size of the pump, 1 1 2 x 3 – 6 is shown in the upper part of the pump curve illustration. note that the size number 1 1 2 x 3 – 6 indicates that the pump has a 1 1 2 inch discharge port, a 3 inch suction port, and a maximum nominal impeller size of 6 inches. Chris explains what a pump performance curve is and how to interpret it. topics covered include flow, pressure, head, capacity, npsh, power curve, best effic.

Then draw a vertical line (shown in yellow below) through the graph at the known flow rate, which is 1,000 gpm. where the two lines intersect is the duty point of the pump. 2. identify the pump's efficiency range. efficiency is the ratio of useful power output to power input. the pump curve shows the pump’s efficiency as different operating. To understand centrifugal pump performance, we need to understand the pump curve. this video explains how to read these charts so we can understand how to a.
