K-TECH Make Air-Operated Double-Diaphragm (AODD) pumps are positive displacement pumps powered by compressed air rather than electricity. They use two flexible diaphragms that move back and forth to draw liquid into one chamber while pushing it out of the other. Why AODD Pumps Are Important: Intrinsic Safety in Hazardous Environments: Driven by compressed air rather than motors, AODD pumps generate zero electrical sparks. AODD are ATEX-compliant and suitable for explosive or volatile zones (such as chemical and oil & gas facilities). Versatile Fluid Handling: Easily handle abrasive slurries, high-viscosity liquids, shear-sensitive materials (like food products or paints), and fluids containing suspended solids. Seal less, Leak-Free Design: Without dynamic mechanical seals or rotating shafts, AODD minimize the risk of fluid leakage, which is crucial for handling toxic, corrosive, or high-value chemicals safely. Run-Dry & Self-Priming Capabilities: AODD pumps can start without manual priming and run dry continuously without damaging components or overheating.
