PUMP SELECTION, SIZING AND INTERPRETATION OF PERFORMANCE 4 • 3 Performance Curve At some point in the pump selection process, the impeller diameter is selected.
Centrifugal pump Pump Curves ... typically plot a separate pump curve for each size of impellor on the same pump performance chart. Smaller impellors produce less pressure at lower flow rates. Pump performance charts with multiple pump curves are shown below.
a centrifugal pump is not fixed as it is in a positive displacement pump. The discharge pressure depends on the pressure available on the suction side of the pump. ... This is the type of curve that all pump manufacturers publish for each model
A centrifugal pump can deliver a wide range of flows. As flow increases, the head decreases. Pump efficiency varies across the flow range. ... A system head curve is valid for only one condition in the pipe system Changing the system (partially closed valve) will
Developing the pump curve The centrifugal pump produces energy in the form of foot pounds per pound of water pumped, and dependent on the volume
- 2 CENTRIFUGAL PUMP Objectives 1. At constant pump speed, determine the characteristic curve (pressure change vs. flow rate) of a centrifugal pump.
Figure 2.5: A typical QH curve for a centrifugal pump; a small flow gives a high head and a large flow gives a low head. Figure 2.6: The QH curve can be determined in an installation with an open pibe after the pump. H is exactly the height of the fluid
Figure 6.10 Typical Centrifugal Pump Performance Curve Effect of over sizing the pump As mentioned earlier, pressure losses to be overcome by the pumps are function of flow – the system characteristics – are also quantified in the form of head-flow curves.
