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...
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 ...
Pump Family Curve – Selection Curve Image 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 ...
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. ...
The tolerance of pump power–flow rate curve in the recommended operating range should be ± 8%. The sample curves shown in Fig. 3.3 represent the performance of one stage of a given pump design. Pump performance curves include the head developed by the pump, the power required to drive th...
