If you are going to get a new pump you could try going into a local supply shop and ask to test the power usage with your Kill-a-watt. If you do this I would note the start up power usage and how long it takes to level out. The reason for doing that is if you try Xringer's suggestion of cycling the power on and off if there is I higher draw at start up you will need to factor that in for the off time.
One option you could try is using a lower flow pump that you will have on at all times with a higher flow pump switching on and off with shorter on times and/or longer off times.
