Air-operated double-diaphragm (AODD) pumps are powerful, versatile pumps used in up to 90% of manufacturing facilities throughout the United States. These should not be confused with diaphragm pumps, as AODD pumps use compressed air and a complex distribution system that reduces wear and tear on the diaphragm. Furthermore, AODD pumps can be used in transfer applications rather than just for metering and dosing.

Air Master manufactures a range of these pumps in multiple sizes and weights to meet the needs of any individual or business.
