Order LookupDouble Diaphragm Pumps
Double diaphragm pumps use two reciprocating diaphragms to draw in and transfer liquids through a system. They are self-priming and can run dry without the risk of damaging internal parts. They can handle liquids with suspended solids, varying viscosities, fuels, and oils. Diaphragm pumps are used for general transfer, dewatering, wastewater treatment, chemical manufacturing, and food processing. Industrial air-operated double diaphragm pumps (AODD) use compressed air to drive the pump, do not produce a spark during operation, and can be grounded, making them suited for environments where hazardous, explosive, or easily-ignitable materials are present. Food grade and sanitary air-operated double diaphragm pumps are rated to handle food, personal care, or dairy products. Natural gas-operated double diaphragm pumps are powered by natural gas and must be flared off to ensure safe operation. Fluid and air end repair kits for double diaphragm pumps keep equipment in good working order.
