I have had the same thoughts as the OP. Why not just increase the inlet opening size? The outlet side is fed by positive displacement, so the flow rate would increase, but the volume it pumps will always be determined by the speed of rotation. I don't see any recommendations for a modification of the screen size to insure adequate flow to the inlet gears. It is puzzling to me
