Double diaphragm pumps operate using an oscillating positive displacement principle. The pump consists of two main fluid housings and a central air control section. Inside each housing, a flexible diaphragm is mounted vertically and connected to a shared shaft. As compressed air enters and exits the air chambers, the diaphragms move in a coordinated push pull motion.

Long term performance depends just as much on what happens before startup and after commissioning as it does on the motor’s electromagnetic design.
