Air Operated Diaphragm Pumps

Everything You Need. Nothing You Don't

Air operated double diaphragm (AODD) pumps are designed for general use. They can easily pump from clean, light viscosity fluids to corrosive, abrasive medium viscosity fluids and can transfer large particles without damage. Due to their pneumatic motor, they could be used in potentially explosive areas. Most ARO® diaphragm pumps are ATEX certified (CE Ex11 2GD X).
