Air Operated Double Diaphragm Pump

An Air Operated Double Diaphragm (AODD) Pump is a positive displacement pump powered by compressed air, widely used for transferring liquids, slurries, chemicals, and viscous fluids.

Working Principle

  • Compressed air alternately pushes two flexible diaphragms
  • One diaphragm creates suction while the other discharges fluid
  • Check valves control fluid direction
  • The process repeats, creating continuous flow

Key Features

  • Air powered – no electricity required
  • Self-priming
  • Dry run capable (no damage)
  • Explosion-proof & spark-free
  • Handles corrosive, abrasive & viscous fluids
  • Can pump solids-laden fluids

Common Materials

Pump Body:

  • Aluminum
  • Cast Iron
  • SS 304 / SS 316
  • Polypropylene
  • PVDF

Diaphragm:

  • PTFE (Teflon)
  • Nitrile
  • Neoprene
  • EPDM
  • Viton

Typical Applications

  • Chemical transfer
  • Paints, inks & coatings
  • Oil & lubricants
  • Wastewater & sludge
  • Food & pharmaceutical liquids
  • Mining & construction sites

Advantages

  • Simple design, low maintenance
  • Safe for hazardous environments
  • Adjustable flow by air pressure
  • Portable and lightweight options

Limitations

  • Pulsating flow (can use pulsation dampener)
  • Lower efficiency than electric pumps
  • Requires clean, dry compressed air

Technical Specifications (Typical)

  • Flow rate: up to 1000 LPM
  • Pressure: up to 8 bar
  • Suction lift: up to 8 meters
  • Solid handling: up to 10 mm (varies by model)
