Air operated diaphragm pumps – also known as AODD or AOD pumps are ideal for an infinite number of functions. Reciprocating diaphragms are controlled by compressed air flowing through an air valve, causing flexible diaphragms to displace volume that, in concert with a series of one-way valves, forces directional liquid flow. AODD pumps are available in an assortment of sizes that will pump from just a few litres per minute to over 1,000 L/min.
