Air Operated Double Diaphragm Pump


  • Sealless Design
  • Low Material Shear
  • Ease of Maintenance
  • Available to Run Dry without Damage
  • Portable
  • Self Priming
  • Easy-to-install
  • Non-Stall Design 
  • Big flow rate: Our AODD pumps apply bigger balls & fluid passage
  • Self-lubricating, and free-maintenance air systems.
  • More flow and less pulsation: Pilot air-distribution valve provides correct and reliable shift signal that avoids stall-out, and provides faster pump trip with more flow and less pulsation.
  • Dual ceramic dynamic seals: More wear-resisting, contaminant resistance. Applicable to severe condition of compressed air supply; Long lifetime.
  • Anti-icing design:With built-in energy-dissipation chamber, it's anti-icing and reduces the discharge air pressure and noise effectively; Cold exhaust air is diverted from ice-prone components.
  • High lift, Stable Operating: Greatly optimized air system ensures the most efficiency, with no air-leakage.
