Centrifugal Pump Monitoring and Determination of Pump
The pump characteristic curve at constant speed is then superimposed on this system head curve (figure 3). Intersection of the two curves dete rmines the flow rate delivered to the system by that particular pump. Q1 is the operating capacity in the example below. Figure 3. Pump Head Curve . Centrifugal Pump Control Bulletin 4 Q1 : Operating capacity without throttling Q2 : Operating …... The P 2-characteristic curve shows the proportion between the mechanical power input of a centrifugal pump and the flow rate Q. If Q rises, P 2

A pump characteristic curve is the graphical representation of the pump performance characteristics, including the range of pressure and flow capabilities at specified speeds, and the corresponding power...
A centrifugal pump can only operate where its curve intersects with the actual system curve (Fig 1). Normally the pump curve does not change except through damage or wear. Normally the pump curve does not change except through damage or wear.

Centrifugal Pump Characteristic Curve Pdf

The performance of a centrifugal pump for clean fluids can only be pre-estimated with required accuracy at the design condition and a characteristic curve in its neighborhood.

  • Centrifugal pump Curves- Characteristics • Head and Capacity –A rating curve indicates the relationship between the head (pressure) developed by the pump and the flow through the pump based on a particular speed and impeller diameter when handling a liquid. –As the capacity increases, the total head which the pump is capable of developing decreases. –In general, the highest head the
  • Centrifugal Pump Characteristic Curve pump performance COTTON CRC WATER TEAM . Most irrigation pumps don’t operate at just one duty point – they operate over a range of duties and need to be selected for this range. An important observation is the overall shape of the flow-head curve. If it slopes down from the left side to the right side, the pump is described as stable and having a non
  • The pump characteristic is normally described graphically by the manufacturer as the pump performance curve. 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
  • Schematic Q-H curves of a centrifugal pump. The head due to pressure differential generated by a pump is called the manometric head, Hman, and it has a unit meter water column [mwc] (see Fig. 7.3).
