Diaphragm pumps, also known as air-operated diaphragm pumps (AODD pump), are positive displacement pumps that operate using compressed air to compress and expand the diaphragm, creating a suction and discharge action that moves fluids. These pumps are ideal for handling viscous or abrasive fluids, including oils, chemicals, and sludge. They are also versatile and can be used in various industries, such as chemical processing, food and beverage, mining, and wastewater treatment.
