Air Driven Liquid Pump An air-driven liquid pump, also known as an air-operated diaphragm pump (AODD), is a type of pump that uses compressed air as its power source to transfer liquids. It is a versatile and efficient pump commonly used in various industries for applications such as transferring fluids, emptying containers, and dosing liquids. The working principle of an air-driven liquid pump involves the reciprocating motion of a diaphragm. When compressed air is introduced into one side of the pump, it pushes the diaphragm in one direction, creating a vacuum on the other side. This vacuum causes the liquid to be drawn into the pump through an inlet valve. As the diaphragm moves back in the opposite direction, it compresses the liquid and forces it out through an outlet valve. One of the advantages of air-driven liquid pumps is their ability to handle a wide range of liquids, including corrosive and abrasive fluids, viscous substances, and liquids with solid particles. They are also capable of dry running without damage, making them suitable for applications where occasional dry operation may occur. The benefits of using air-driven liquid pumps include: Versatility: Air-driven liquid pumps can handle various types of liquids, making them suitable for a wide range of industrial applications. Self-priming: These pumps can self-prime, meaning they can draw liquid from a lower level without the need for external priming. Ability to handle solids: The diaphragm design of these pumps allows them to handle liquids containing solids or particles without clogging or damage. Simple operation and maintenance: Air-driven liquid pumps have a relatively simple design, making them easy to operate and maintain. They are often constructed from durable materials, ensuring long-term reliability. Adjustable flow and pressure: The flow rate and discharge pressure of air-driven liquid pumps can be easily adjusted by regulating the air pressure, allowing for precise control of liquid transfer.
