K-TECH Aluminum Air-Operated Double Diaphragm (AODD) pumps are widely used for transferring various industrial fluids, including fuels, oils, paints, and wastewater, especially in non-corrosive to moderately abrasive applications. K-TECH AODD Pumps key benefits include inherent safety in hazardous environments due to air power (no sparks), ability to run dry without damage, self-priming capabilities, and the capacity to handle solids and viscous liquids. They also offer deadhead capability (stops when discharge is closed), easy flow rate adjustment, and are generally lightweight and simple to maintain.
