Made of FDA-compliant stainless steel components, these air-operated double diaphragm (AODD) pumps are commonly used in food processing, pharmaceutical, and cosmetic industries and can handle a variety of viscosities and foods incorporating oils. They are designed to be easily taken apart for cleaning and resist corrosion and chemicals such as acids, caustics, and solvents.
Double diaphragm pumps reduce the possibility of pressure buildup within the pump, and have a sealless design which helps reduce leaks. They are self-priming and able to run dry for limited amounts of time. Driven by compressed air, these pumps are a good choice in hazardous environments where sparking is an issue, or in areas where electricity isn't readily available.
