Abstract
This pump with a battery-powered drive device comprises a circular elastic diaphragm () and two valves (), which has a diameter of 3 to 25 mm and is subjected to a compressive prestress of between 1'10and 4'10Pa capable of enabling it to return to its rest position at a maximum working frequency of between 8 and 12 Hz with a travel of between 0.2 and 2 mm, corresponding to a maximum flow rate of 1.5 to 2.5 l/h. The drive device comprises an electromagnet () in direct contact with the diaphragm (), a standard power supply battery, the available energy of which is from 7000 to 10'000 J, means for analyzing the supply current for the electromagnet and for detecting, at each pumping drive cycle, a minimum defined intensity of the supply current corresponding to the closure of the gap of the electromagnet () and means for interrupting the supply current once this minimum intensity has been reached.
