The reverse running speed is the speed that occurs in a centrifugal pump when the fluid flows in reverse direction through the pump at a certain head (i.e. difference in total head between discharge nozzle and suction nozzle). This situation can arise in systems whose system characteristic curves have high static heads (H sys,0), but it can also be observed in .

Centrifugal pumps are widely used in various industries for transferring liquids and gases. Understanding the characteristic curve of a centrifugal pump is crucial for efficient operation and maintenance. The characteristic curve of a centrifugal pump is a graphical representation of its performance under different operating conditions. By analyzing this curve, operators can determine the pump's efficiency, flow rate, pressure, and power consumption.
The first curve under pump performance characteristic is the head Vs. flow rate curve. It is also known as a pressure vs. quantity curve. To draw this curve head is plotted on Y-axis, and the flow is plotted on X-axis. You can see the sample HQ curve in the image here. Now let’s convert this curve to a word so that
Centrifugal Pump Flow Rate Chart
The centrifugal pump flow rate chart illustrates the relationship between the flow rate (in cubic meters per hour or gallons per minute) and the pump's head (in meters or feet). This chart helps operators determine the maximum flow rate that the pump can handle at a specific head. By referencing the flow rate chart, operators can select the appropriate pump size for their application and ensure optimal performance.
Centrifugal Pump Performance Chart
The centrifugal pump performance chart provides a comprehensive overview of the pump's performance characteristics, including efficiency, power consumption, and head. By analyzing this chart, operators can identify the pump's operating range, efficiency peaks, and potential issues such as cavitation or overloading. Understanding the performance chart is essential for optimizing the pump's performance and avoiding premature failure.
Centrifugal Pump Impeller Size Chart
The centrifugal pump impeller size chart displays the relationship between the impeller diameter and the pump's performance parameters, such as flow rate and head. Selecting the correct impeller size is crucial for achieving the desired flow rate and pressure. By referring to the impeller size chart, operators can ensure that the pump operates within its design parameters and delivers efficient performance.
How to Read a Pump Curve Chart
Reading a pump curve chart may seem daunting at first, but with some guidance, it becomes a valuable tool for pump operators. The x-axis typically represents the flow rate, while the y-axis shows the head or pressure. The curve itself indicates the pump's performance at various operating points. By analyzing the curve, operators can determine the pump's efficiency, power consumption, and operating range. Understanding how to read a pump curve chart is essential for efficient pump operation and troubleshooting.
Centrifugal Pump Efficiency Chart
The centrifugal pump efficiency chart illustrates the pump's efficiency at different flow rates and heads. Efficiency is a critical parameter that indicates how effectively the pump converts input power into hydraulic energy. By referencing the efficiency chart, operators can identify the pump's optimal operating conditions and make adjustments to improve overall efficiency. Monitoring the pump's efficiency over time is essential for detecting performance degradation and implementing maintenance measures.
Centrifugal Pump Flow vs Pressure
The relationship between flow rate and pressure is a key consideration in centrifugal pump operation. As the flow rate increases, the pressure generated by the pump decreases. Understanding this relationship is crucial for maintaining the desired flow rate and pressure in the system. By analyzing the centrifugal pump flow vs pressure chart, operators can optimize the pump's performance and ensure reliable operation.
Pump Efficiency Curve Chart
The next pump performance curve is the efficiency curve. All the charts shown here are plotted for a constant speed fixed diameter impeller pump. From this chart, you can see that
The purpose of a suction strainer is to act as a particulate strainer or filter ahead of the pump. This prevents large particles from entering the pump. Before the introduction of the low-flow/high-head multi-stage centrifugal type pump, turbine type pumps were used almost exclusively for on/off boiler feed service for steam boilers .
