Abstract: The present invention relates to a method for operating an undulating diaphragm pump comprising an undulating diaphragm and actuating means of the undulating diaphragm electrically powered according to a given frequency or voltage to make the undulating diaphragm oscillate and undulate. According to the invention, the method consists in modifying the electrical supply frequency and/or voltage of the actuating means according to at least one operating parameter, determined in advance, of the undulating diaphragm pump.
