The pump provides power to the cooling loop by moving coolant at some flowrate through the resistance (water to wall friction, and water to water friction) of the cooling loop.
Pressure * Volumetric Flowrate = Power
If you go to

You can see that 1 liter/second * 1 kilopascal = 1 Watt.
(enter liters/second * kilopascals as liter*kilopascal/second)
Comparing the "fluid power" to the pump's electrical power consumption, gives you some measure of the efficiency which the pump is operating at. (Be aware that the pump manufacturer's spec for power consumption is likely to be substantially higher than the actual pump power consumption in a watercooling loop. The manufacturer's spec is just a maximum.)
