What is AODDP - Air Operated Double-Diaphragm pump?
Air Operated Double Diaphragm Pumps (AODDPs) are positive displacement pumps powered by compressed air. These pumps are commonly used in various industries to handle various fluids, including abrasive and viscous liquids.
AODDPs work on the principle of alternate and repeated strokes of two flexible diaphragms, which move fluid through the pump. When compressed air enters one air chamber, it moves the rod to the left, which increases the volume of pumping chamber B while decreasing the volume of pumping chamber A. As the rod completes the stroke, the air distribution system vents chamber A. The process is repeated when compressed air is directed to chamber A again. The second stroke works in a similar way, with the fluid being discharged from chamber B and drawn to chamber A.
One of the main advantages of using AODDPs is their versatility. They can handle a wide range of fluids, including those with high viscosity or abrasive properties, making them suitable for use in industries such as chemicals, food and beverage, mining, and pharmaceuticals. Additionally, AODDPs are relatively easy to maintain and can run dry without damaging the pump, making them a reliable and cost-effective option for fluid handling.
AODDPs have a variety of applications across different industries. In the chemical industry, they are used to transfer acids, bases, solvents, and other chemicals. In the food and beverage industry, they are used for the transfer of food products, such as chocolate, syrups, and juices. In the mining industry, AODDPs are used to handle slurry and abrasive fluids. In the pharmaceutical industry, they are used to transfer various liquids and creams.
In conclusion, AODDPs are versatile, reliable, and cost-effective pumps that are commonly used in a wide range of industries to handle different types of fluids. Understanding the basics of AODDPs is crucial to ensure that they perform optimally in a specific application.
