I'm not sure about this - unless the Barracuda operates differently from other pumps, the ability to restrict the outlet does reduce flow, but that isn't linked to power draw - reducing the output/flow typically increases the back pressure on a pump but I'm not sure that it reduces power useage. |
Power draw will reduce slightly as head pressure increases, this is typical for most centrifugal style pumps.
You can see in the spec sheet how the power drops.
