Introduction
air operated diaphragm pumps (AODPs) are a type of positive displacement pump that can move fluids with high efficiency and great reliability. It does not use electricity as the driving force, but rather compressed air that makes them suitable for use in hazardous or explosive environments. Today, in this introduction, you will be learn about the basic operating principles of air operated diaphragm pumps as well as their added advantages and common applications.
How AODPs Work
Air-operated diaphragm pumps are fabricated around a simple mechanic: On the shaft between two diaphragms is a common channel in these pumps. Compressed air pushes one of the diaphragms to the other, and fluid at the other side is displaced by this. There’s less pressure on the fluid, and more will be sucked into the pump because a vacuum is subsequently created under it. The process repeats, enabling AODPs to pump fluid continually.
The Main Merits of Air-Operated Diaphragm Pumps
