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.
The safe handling of toxic, volatile, or climate-relevant media is one of the central challenges in modern industrial processes. Many new applications—from CO₂ cycles and hydrogen electrolysis to industrial refrigeration—cannot be realized without hermetically sealed pump systems.
