Air operated double diaphragm pumps
Built for Power, Built to Last

Iwaki Air AODD pumps are engineered for maximum utility. They are portable and easy to install, operate, and maintain. Infinitely variable flow rates and variable discharge pressures can handle a large range of fluids, including corrosive chemicals and flammable liquids. The AODD pumps can run dry, self-prime and dead-head without damaging the pump. Other design elements that distinguish Iwaki Air AODD pumps include body stabilization features to ensure heat resistance, and sound suppression construction to reduce both mechanical noise and compressed air noise.

These pumps are built for power. A higher power output means the pump can operate with less applied air pressure compared with many competitor’s pumps – often outperforming pumps that may have a higher listed flow rate.

Looped C-Spool Air Valve
Revolutionary new spring design uses stronger, light-weight material for a smoother stroke with less wear and tear of all spool components (fully interchangeable with C-Spool model pumps).

Checkmark Lube-free Operation
Clean, environmentally friendly design is engineered without the need for lubrication. Lube-free operation extends the life of all air motor parts
Checkmark Independent and Modular Pilot Valve
Industry-leading pilot valve system design is fully independent and virtually non-wearing. Static seals are dirt and moisture resistant. Pilot valve and springs are made from high tensile stainless steel that will not bend or rust. Faster cycles with shorter strokes will extend diaphragm life.
Checkmark Large Diameter Ports
Oversized ports allow air contamination to pass through the pump eliminating blockages and freezing.
Checkmark Reduced Pump Stalling
The unique new Looped C-Spool greatly reduces the pump stalling
Checkmark Resists Freezing
Compressed air expands gradually through our innovative staged air chamber exhaust system to reduce freezing. Large air port design allows contaminated air to pass through the pump and out the exhaust.
