<p>An undulating diaphragm pump having a propulsion chamber for receiving said diaphragm, wherein the diaphragm has mechanical characteristics that vary from an inlet of the propulsion chamber towards an outlet of the propulsion chamber in such a manner that, when the diaphragm is actuated to deform with a traveling wave that propagates from the inlet towards the outlet of the propulsion chamber in order to propel the fluid, the propagation speed of the wave in the diaphragm in any cross-section relative to the movement of the fluid inside the propulsion chamber is equal to or greater than the mean travel speed of the fluid in said section.</p> |
