How an AODD Pump Works

Two flexible diaphragms are connected by a common shaft. Compressed air alternately pressurises one chamber while the other draws fluid. Each stroke: one diaphragm displaces fluid on discharge while the other creates suction.

Key Advantages of AODD Pumps

  • ✅ No electricity required — runs on compressed air
  • ✅ Seal-less design — no mechanical seal to fail
  • ✅ Self-priming from dry condition
  • ✅ Dry-run capable without damage
  • ✅ Handles solids, slurries, and abrasive fluids
  • ✅ Safe for flammable and toxic chemicals
  • ✅ Variable flow rate — just adjust air pressure
  • ✅ Reversible flow direction

Available Materials

Body: PP, SS316, Aluminium, PVDF, Cast Iron
Diaphragm: Santoprene, PTFE, Buna-N, Viton, Neoprene
