AODD (Air operated double diaphragm pump) is a positive displacement (PD) pump, which consists of two pumping chambers. Both these chambers are filled alternatively and get discharged by the movement of the flexible diaphragm.
Features of Air Operated Double Diaphragm Pump
Here are the primary advantages and features of air-operated double diaphragm pump offered by air-operated double diaphragm pump suppliers:
- These AODD pumps are considered to be free from leaks. There are stationary seals between wetted parts and the external environment, so leakage occurs if either or both the diaphragms fail.
- As general maintenance activity, the diaphragms must get replaced regularly.
- Compared to being in the mechanically driven diaphragm pumps, the diaphragms suffer much lesser wear and tear in the AODD pump. This is due to the pressure of balancing by these compressed air supplies.
- The AODD pumps have the capability of handling viscous and abrasive fluids, slurries and sludges as well. They also have gentle pumping actions, which makes them suitable for shearing sensitive fluids.
- It has 4 internal valves, which use either the ball or flap design. The ball valves provide a much better seal and are far less prone to wear than flap designs.
- AODD pumps have no internal seals or even moving components that require cooling or lubrication. Hence, these can easily run without any damage. These pumps are quite self-priming are also capable of suction lifting to 8m.
Application of AODD pumps
Now we will discuss applications offered by air operated double diaphragm pump manufacturers. AODD pumps are primarily suited in hazardous areas as compressed air is the power source instead of electricity. Also, the AODD pump gets submerged easily, as long as the vent is above the liquid level. Some of the other applications of the AODD pumps include:
- Mining industry
- Coatings
- Ceramics
- Chemical
- Pulp and paper
- Oil and gas
- Wastewater treatment
