Who We Are
AODDFlow is an air-operated double diaphragm pump manufacturer based in Guangzhou, China. We build AODD pumps from 1/4" to 3" in PTFE, polypropylene, stainless steel and aluminium — and we supply the cross-referenced replacement parts that keep every brand of AODD pump running.
Industrial buyers face a simple problem: OEM parts carry long lead times and premium prices, while aftermarket parts are often poorly documented. We solve it by combining factory-direct pump manufacturing with a parts catalog that is cross-referenced against real OEM part numbers — so buyers can find, confirm and order the right part in one place.
