You've got several options.
As far as I know, everyone who has set their monitor refresh rate to 60Hz has gotten rid of the flickering.
If you are willing to go ghetto, a tin can placed around the pump will provide substantial shielding. (Make sure the can is ferromagnetic by checking that a magnet will stick to it.) Multiple tin cans be nested for greater shielding. I've also heard of one person making a box of 16 gauge sheet steel and duct tape.
Move the pump even farther away.
Get a better shielded monitor.
Do you have a steel case, or an aluminum one?
