A diaphragm pump has two diaphragm chambers and two diaphragms. Diaphragms are connected to each other by a common shaft and move parallel to each other at the same time. While one of the diaphragms moves by pushing with the help of compressed air, the other diaphragm connected to it with a shaft expels the residual air in front of it. When the stroke is completed, the air valve automatically changes the direction of the compressed air and the same movements are repeated in the other direction. Continuously repeated reciprocating motion alternately provides suction and initiation motion to the fluid in each chamber. Constantly repetitive back and forth motion causes the fluid to be pumped by entering each room in turn and leaving the others. The suction and discharge valves regulate the flow of the fluid from the entrance to the exit of the chambers.
Ball and flap valves automatically control the flow of the fluid at the entrance and exit of the chambers. Ladle valves allow the passage of solid parts close to the pipe diameter during the pumping of fluids of different viscosities. Ball valves, on the other hand, provide the passage of small solid parts.
