Double-outlet and double-inlet integral pneumatic diaphragm pump

The invention discloses a double-outlet and double-inlet integral pneumatic diaphragm pump. The double-outlet and double-inlet integral pneumatic diaphragm pump comprises a center body, a left pump body and a right pump body. The left pump body and the right pump body are clamped on the two sides of the center body respectively in a sealed manner, and pump cavities are formed between the left pump body and the center body and between the right pump body and the center body respectively. The center body is provided with a center hole and an air valve installation hole. A center shaft is sleeved with the center hole, and an air valve capable of controlling the center shaft to move left and right is sleeved with the air valve installation hole. Diaphragm pieces are fixed to the two ends of the center shaft respectively, and air cavities are formed between the two diaphragm pieces and the center body respectively. Liquid cavities are formed between the two diaphragm pieces and the corresponding pump bodies. Two independent water inlets communicated with the liquid cavities in the two sides respectively are formed in the bottom of the center body. Two independent water outlets communicated with the liquid cavities in the two sides respectively are formed in the top of the center body. The double-outlet and double-inlet integral pneumatic diaphragm pump is reasonable in structural design, convenient to install and easier and more convenient to operate; and due to the fact that the double-outlet and double-inlet integral pneumatic diaphragm pump can be used for drawing two kinds of products at the same time, the neutralizing process is omitted, and cost is reduced.
