Nano, this is why you need to understand how stuff works before you post about how it works. The pump "does work" when it moves water. The more water it moves the work is done. The more work that is done, the more power is needed. The pump is actually creating the same " pressure" no matter how much water moves, the amount of pressure that the pump creates determines how much water is moved. If there is lots of static head pressure, the pump has less pressure to overcome the dynamic head pressure (friction loss) to move water. So when you reduce the friction, there is more pressue left to allow a higher velocity of water to use up the pressure that is left.
