It reveals that a good pressure gage and a flow meter allow one to test the performance of a pump in his or her own shop and create a curve.Pelikan, BobNational Driller
Pump Family Curve – Selection CurveImage Source – pumps and systems This is a sample family curve that is used to select the pump. Head and flow rates are on the Y and X-axis. On the Y-axis, you can see the impeller diameter is marked. Percentage shows the efficiency of the Pump...
Performance curve for Vacuum pump Performance curve for Compressor Each G-2RB type can be applied both as vacuum pump and compressor in continuous operation over the total stated performance curve range. The motors are available as standard for the input voltage range of 50 and 60 Hz and for ...
Horsepower curves are essential in selecting the proper pump motor, and can be used in the same way as the efficiency curve to determine the relative operating cost of a particular pump. For example, when we take electric motor efficiency into account, one horsepower equals approximately three-qu...
How to read a pump performance curve remains a topic of great interest across the food, dairy, beverage, and pharmaceutical processing industries, so in this post we provide important information on two of our most popular styles — Centrifugal and Positive Displacement. A pump performance curve ...
When a pumps operates in the far right of its curve with poor efficiency - the pumps Carry Out. Shutoff Head The Shutoff Head is the head produced when the pump operates with fluid but with no flow rate. Churn A pump is in Churn when it operates at shutoff head or no flow. ...

defined by extrapolation of the data curve (for ex. in Flowrate=f(Power) curves). In other cases they are rather defined through the voltage threshold and the I=f(U) characteristics. The thresholds determination and behaviour around them is one of the more difficult features of the pump ...
