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.
Exceptional diaphragm pump lifetime is no coincidence, at KNF it is engineered. When a pump runs for more than 11 years under defined test conditions, OEMs benefit from fewer failures, lower costs, and greater confidence in critical applications.
The next step in a successful collaboration: the Wilo Group has acquired a majority stake in systems engineering company PreFab, thereby strengthening its strategic position in the digital and AI age.
