1. How can i find a pump performance curve for a centrifugal
pump ?
The power to lift the water is according to:
Power_W = (Mass_kg x Gravity_m/s/s x Height_m) / time_s
Thus:
P = (1140 * 9.81 * 108.74 ) / 1 = 1.21MW.
The actual power to drive the pump is more, according to pump efficiency, which could be 0.8, so
motor power is 1.5MW or so.
A lot of pump performance curves are on the internet, but use traditional units (USA). This is around
1600 horse power. This might use a 2000hp prime mover. The majority of installed pumps were not
initially sourced for their current function. Often, a line levy pump in a plant changes and the pump
that once providedcooling water to an injection molding machine is now needed to transfer oil from
a rail car to a tank. Unfortunately, this leads to numerous problems for the pump and the company.
Pumps operate where the pump curve crosses the system curve. If you move a pump from one
system to another, this means that the system curve is different. This new system may cause the
pump to operate away from its best efficiency point, leading to vibration and other component
problems that are merely symptoms water treatment plant of a mis-matched pump and system.You
need to convert I suppose, so the head becomes 357 feet and the flow is 18,069 US gallons per
minute. Then search images for performance curves using the parameters in both systems of units.
Note the pump performance curves etc use flow and head. The velocity is more to do with pipe size,
given the above. This is a large head for a single stage centrifugal pump (100 feet or 30m typical), so
you are looking for a multistage centrifugal pump or some other pump type. Here are some notes on
selecting pumps, and there are curves for larger pumps on this site too:

Also see the National Pump Company. This catalog has multistage pumps and curves that meet these
needs:
