Yamada Air Operated Double Diaphragm AODD Pumps

Yamada Air-Operated Double Diaphragm (AODD) Pumps are versatile, pneumatically driven pumps that use compressed air to alternately flex two diaphragms, creating a smooth and continuous flow of fluid. Because they contain no motor or mechanical seals, they are inherently safe for handling flammable, corrosive, and chemically aggressive fluids, making them a popular choice in industries such as chemical processing, pharmaceuticals, food and beverage, mining, and paint and coatings. Yamada's AODD pumps are self-priming, capable of running dry without damage, and can handle everything from thin solvents to thick, viscous slurries and solids-laden liquids with ease. Available in a wide range of materials — including aluminum, cast iron, stainless steel, polypropylene, and PVDF — and with various elastomer options for wetted parts, Yamada AODD pumps are highly adaptable to specific application requirements, delivering reliable, pulsation-controlled performance with minimal maintenance in even the most demanding environments.
