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.

Vacuum pumps are essential to many manufacturing and processing applications, but they are also a source of heat. While modern vacuum pumps are efficient and minimize this heat loss, a certain amount of heat generation is a natural by-product of vacuum generation that can never be completely avoided. Traditionally, much of this heat is allowed to dissipate into the surrounding environment.
