A flexible diaphragm can be moved to line opposite surfaces of a vehicle container so that incompatible fluids alternately can be transported in the vehicle without the need for cleaning it. The container is loaded and unloaded in a manner which causes the diaphragm to neatly lie against the container surface without forming wrinkles, creases or bubbles. The movement of the diaphragm is controlled by the sequence and timing by which inlet and outlet conduits on opposite sides of the diaphragm are opened and closed.

The method of loading an enclosed container which has its interior changeable into different chambers for non-compatible liquids by a flexible diaphragm that alternately lines opposite portions of such container, comprising the steps of: A. emptying the liquid from said container and flowing air at atmospheric pressure into the chambers on both sides of said diaphragm; B. sealing one of said chambers so as to trap air at atmospheric pressure on one side of said diaphragm; C. venting the opposite side of said diaphragm to the atmosphere and flowing liquid into the chamber on said opposite side in such manner that the trapped air on said one side of said diaphragm is displaced by rising liquid, said displaced air moving the upper portion of said diaphragm in one direction while the rising liquid moves the lower portion of said diaphragm in the opposite direction, whereby said diaphragm is stretched out in tension as it is moved upwardly into contact with said container; D. after said container is partially filled with liquid, releasing said trapped air by venting said one side of said diaphragm to the atmosphere; E. continuing to load liquid into said container; and F. sealing both of said chambers when the loading of said container is complete.
