AODD Pumps Report

AODD Pump report

An AODD pump, or Air-Operated Double-Diaphragm pump, is a type of positive displacement pump that uses compressed air to move fluidsIt utilizes two flexible diaphragms that move back and forth, creating suction and discharge cycles to move the fluid. These pumps are known for their versatility and ability to handle a wide range of fluids, including those with high viscosity and suspended solids, as well as corrosive and abrasive materials. 
 
How it works:
  • Compressed air drives the diaphragms:
    Compressed air is directed into the pump, pushing one diaphragm while creating a vacuum on the other side. 
     
  • Reciprocating motion:
    This back-and-forth motion of the diaphragms creates a pulsating action that draws fluid into the pump and then expels it. 
     
  • Check valves control flow:
    Check valves prevent backflow and ensure that fluid moves in the desired direction during each cycle. 
     
  • No rotating parts in the fluid chamber:
    AODD pumps don’t have rotating parts like impellers, which simplifies maintenance and reduces the risk of leaks. 
     
Key features and benefits:
  • Versatility: AODD pumps can handle a wide range of fluids, including those with solids, high viscosity, and corrosive properties. 
     
  • Simple design: The absence of rotating parts and seals reduces maintenance needs and the risk of leaks. 
     
  • Explosion-proof: They can be used in hazardous areas due to their pneumatic operation. 
     
  • Self-priming: AODD pumps can often self-prime, meaning they can draw fluid from a source without needing to be manually filled. 
     
  • Dry-run capability: Some AODD pumps can run dry for a short period without damage. 
     
Common applications:
  • Chemical processing: Transferring acids, solvents, and other chemicals.
  • Wastewater management: Pumping sludge, slurries, and other waste materials.
  • Mining: Dewatering, transferring abrasive slurries, and handling various mining fluids.
  • Food and beverage: Handling food products, syrups, and other liquids.
  • Pharmaceuticals: Transferring and dispensing various fluids in a controlled environment.
