I'd recommend that you follow Bosswrench's advice and check with the pump manufacturer about the screen mesh size. The finer the screen, the easier it is to get clogged which doesn't have a good outcome. I don't think you want to be pulling the pan periodically to clean the screen. Oil can get "gunky" unless you plan on changing it at pretty short intervals. Also a good qustion on how you are securing the magnets.
