An air-operated double diaphragm (AODD) pump, also known as an air diaphragm pump, is a type of pneumatic diaphragm pump that utilizes air valves to guide compressed air back and forth between the two sides of the pump.
A diaphragm pump works by utilizing the reciprocating motion of flexible diaphragms to create suction and discharge pressures. When the compressed air is directed to one side of the diaphragm, it flexes inward, creating a vacuum and drawing fluid into the pump chamber. Simultaneously, the opposite diaphragm pushes fluid out of the pump chamber. The back and forth motion of the diaphragms creates a pumping action, allowing for efficient fluid transfer.
AODD pumps, including the popular AEROPRO diaphragm pump, are designed with two diaphragms that alternate their movements to provide continuous pumping. This double diaphragm configuration ensures a smooth and consistent flow of the fluid.
Air-operated double diaphragm pumps find applications in various industries due to their versatility. Some common applications include:
Transferring chemicals, solvents, acids, and corrosive liquids.
Circulating, transferring, and dispensing paints, inks, and coatings.
Transferring food products, syrups, sauces, and beverages.
Pumping slurry, wastewater, and abrasive materials.
Handling crude oil, drilling mud, and wastewater.
Transferring pharmaceutical ingredients, creams, lotions, and personal care products.
Air-operated double diaphragm pumps, such as the AEROPRO diaphragm pump, offer several advantages:
Diaphragm pumps can self-prime, allowing them to start pumping without the need for additional priming mechanisms.
These pumps can run dry without causing damage to the pump or diaphragms, making them suitable for intermittent or variable flow applications.
AODD pumps can handle a wide range of fluids, including viscous liquids, abrasive slurries, and corrosive chemicals.
AODD pumps are compact and lightweight, making them easy to transport and install in various locations.
In conclusion, air-operated double diaphragm pumps are reliable and versatile fluid transfer solutions. Their unique operating principle, along with their durability and compatibility with various fluids, makes them a preferred choice in numerous industries.
