Diaphragm pump, also known as a Membrane pump, is mainly composed of motor, transmission components, flexible diaphragm, and check valves. It utilizes a flexible diaphragm that reciprocates back and forth, creating a temporary chamber, which both draws in and expels fluid through the pump. When the volume of a chamber of pump is increased, the pressure decreases, and fluid is drawn into the chamber. When the chamber pressure later increases from decreased volume, the fluid previously drawn in is forced out. Finally, the diaphragm moving up once again draws fluid into the chamber, completing the cycle.

AJK produces complete lines of mini diaphragm pumps for more than 15 years, like AJK-B1201, AJK-B2701, AJK-B3601, etc. Please feel free to contact us if any requirements on the mini diaphragm pumps, thanks
