The new device consists of round vessel, a plastic cup moves freely up and down round a rod fixed on the center of the bottom of the vessel. The cup job is to convey the; less density liquid out vessel. Spill water in the vessel until the water height become equal the height of pipe which is parallel with the vessel, and then spill a quantity from the other liquid which is different of density comprising with water simply less than water density. After that insert which it contains water and diesel (for example) inside the vessel, after that the water move down and diesel moves up then balance between the original liquids and the water start spilling from the pipe, and diesel start spilling through plastic cup into the pipe then out the vessel, like this system continue delivering the excess water or excess diesel which added to the original quantity of liquids.
