AODD Pump Operation: A Comprehensive Guide
AODD Pump Operation: A Comprehensive Guide An Air-Operated Double-Diaphragm (AODD) pump is a type of positive displacement pump driven by compressed air. Working Principle of AODD Pump AODD pumps work by using two opposing diaphragms connected to a rod. Compressed air moves the diaphragms, which creates suction and discharge cycles. Check valves control the flow of liquid into and out of the chambers. Advantages of AODD Pump AODD pumps can handle solids without clogging and are self-priming, making them suitable for lifting fluids from a lower level. They are gentle on sensitive fluids and can handle a wide range of viscosities. AODD pumps have no mechanical seal, which eliminates the risk of leakage. The flow and pressure can be easily adjusted using air pressure. AODD pumps do not require an electric motor, making them suitable for hazardous environments. Limitations of AODD Pumps AODD pumps are limited by the available air pressure. They also have pressure pulsation due
