Definitions

Double diaphragm pumps have long been known in the art. They are known to transport even difficult conveyed goods and are based on the fact that two membranes in opposite membrane chambers alternately fill a liquid space in a suction movement and empty it in a pressure movement. Ball valves ensure a given conveying direction by blocking the inlet side during the pressure movement and the outlet side during the suction movement.
the diaphragms are coupled by means of a rigid connecting shaft and therefore move in a push-pull manner.
FIG. 1 shows a double-membrane pump with a pump housing 10, which is composed essentially of a first line section 1 on the left side and a second line section 2 on the right side. Both line sections 1 and 2 each form a diaphragm chamber, the first diaphragm chamber 11 and the second diaphragm chamber 21. These diaphragm chambers 11 and 21 are bounded by ball valves 5 and 6, of which the ball valves designated 5 are open and the ball valves 6 are closed , The membrane chambers 11 and 21 are divided by a respective membrane 12 and 22 in a liquid chamber 13 and 23 and an air chamber 14 and 24, respectively.
the first diaphragm chamber 11 In the illustrated position, the first diaphragm chamber 11 is filled with the fluid and therefore, the first fluid chamber 13 is expanded and large, while the first air chamber 14 is compressed by the first diaphragm 12 and small. Conversely, in the second diaphragm chamber 21, in which the air chamber 24 is large and the fluid chamber 23 is compressed and small.
each of the connecting shafts 15 and 25 functions like the continuous connecting shaft 18 in FIGS. 1 and 2
an asynchronous control of the connecting shafts 15 and 25 by the controllers 20 can now also take place. This makes it possible on the one hand to avoid turbulent flows in the process 4, on the other hand, it is also possible like still in FIG. 5 is shown to mix different feeds into the process and dose it differently.
