Air Operated Diaphragm Pump
What is an Air Operated Diaphragm Pump?
An air operated diaphragm pump is a type of positive displacement pump powered by compressed air. It uses two flexible diaphragms that move back and forth to pump fluid, making it suitable for transferring abrasive, viscous, corrosive, or solid-laden liquids. Also known as a double diaphragm pump or AODD pump, it is widely used in industries such as chemical processing, food and beverage production, mining, and wastewater treatment. These air-operated pumps are valued for their self-priming, dry-running, and heavy duty capabilities.
FAQ about Air Operated Diaphragm Pump
How does an air operated diaphragm pump work?
It uses compressed air to move two diaphragms back and forth. This action draws in and pushes out fluid through inlet and outlet valves in a repeating cycle. This motion provides smooth flow rates and effectively manages pulsation.
What types of fluids can be transferred with an air operated diaphragm pump?
An air operated diaphragm pump can handle a broad spectrum of liquids, including water, oils, slurries, corrosive chemicals, abrasive fluids, and viscous substances. It can also safely transfer fluids with suspended solids, making it highly versatile across industrial applications.
What are the advantages of using an air operated diaphragm pump?
It’s versatile, self-priming, can run dry without damage, handles solids and abrasive materials, and works with a wide range of fluids. It’s also easy to install and safe for hazardous areas.
How do you maintain an air operated diaphragm pump?
To maintain an air operated diaphragm pump, regularly inspect the diaphragms, valves, and seals for wear, clean internal components and fluid lines, and ensure the compressed air supply is clean and adequately regulated. Monitor for changes in pulsation or flow rate, and replace any worn or damaged parts to ensure your AODD pump continues to run smoothly and efficiently.
