Abstract
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.
