The Flowrun FRAOD Series Air-Operated Double-Diaphragm (AODD) pump is powered entirely by compressed air, making it intrinsically safe for handling flammable, explosive, or hazardous liquids without the risks associated with electrical operation. With no mechanical seals or gland packing, the FRAOD is designed to provide leak-free operation.
Its self-priming capability and ability to run dry without damage make it highly versatile for chemical transfer, barrel loading and unloading, filter press operations, and other demanding industrial applications.
