Wilden AODD (Air-Operated Double Diaphragm) pumps are a type of positive displacement pump that uses compressed air to move fluids, such as water, chemicals, and petroleum products. AODD pumps are used in various industries, such as mining, chemical processing, and wastewater treatment, due to their ability to handle abrasive, viscous, and shear-sensitive materials.
Wilden AODD pumps consist of two flexible diaphragms that are connected by a common shaft. When compressed air is introduced to one diaphragm, it flexes inward and draws fluid into the pump chamber. At the same time, the other diaphragm flexes outward and forces fluid out of the pump chamber. When the compressed air is released, the diaphragms return to their original position and repeat the process.
Some benefits of Wilden AODD pumps include:
Self-priming: AODD pumps can self-prime and handle fluids with varying viscosities and consistencies.
Dry running: AODD pumps can run dry without damage to the pump, which makes them suitable for batch processing and intermittent use.
Easy maintenance: AODD pumps have a simple design that makes them easy to disassemble and clean.
Safe operation: AODD pumps do not use electricity, which reduces the risk of electrical hazards.
Proper selection, installation, and maintenance of Wilden AODD pumps is important to ensure safe and efficient operation. The pump should be selected based on the fluid being pumped, the flow rate required, and the pressure and temperature of the system. The pump should be installed according to manufacturer instructions and checked regularly for leaks, wear, and other signs of damage. Additionally, regular maintenance and inspection should be performed to ensure that the pump is in good working condition and that any issues are addressed promptly.
