AODD PumpsAir Operated Excellence
Versatile, positive-displacement pumps powered entirely by compressed air. Built for durability and reliability, ideal for transferring high-viscosity, abrasive, and solid-laden fluids without electrical power.
Double DiaphragmOperation Explained
Inside the pump, two elastomer diaphragms work in tandem to create continuous flow:
Air Pressure
Compressed air enters the air chamber behind one diaphragm, pushing it forward.
Fluid Displacement
This movement displaces fluid from one chamber while drawing new liquid into the opposite chamber.
Check Valves
Check valves ensure that fluid flows only in one direction, preventing backflow.
Continuous Cycle
As air alternates between chambers, the diaphragms oscillate, creating continuous pumping.
Why ChooseAODD Pumps
No Electricity Required
Perfect for ATEX zones, chemical plants, outdoor sites, and emergency operations where electrical pumps are not safe or practical.
Highly Versatile Fluid Handling
Handles clear liquids, corrosive chemicals, slurries, oils, viscous materials, and fluids containing solids or fibrous matter.
Self-Priming Capability
Effortlessly draws liquid from dry suction lines—ideal for startup or applications with inconsistent fluid supply.
Seal-less, Leak-Free Design
With no mechanical seals, the pump minimizes leakage risks and reduces maintenance downtime.
Dry-Run Safe
Can operate without fluid for short periods without causing mechanical damage—excellent for intermittent or variable-flow processes.
Easy to Maintain
Modular design allows quick diaphragm and valve replacement, reducing repair time and operational disruption.
