ARO air operated double diaphragm pumps (AODD pumps) are designed for general fluid transfer. Our pumps reliably transfer a wide variety of fluids, from clean, light viscosity to medium viscosity. They can pump large particles without damage.

Metal or plastic diaphragm pump casings can easily handle corrosive and abrasive fluids. Most ARO diaphragm pumps are ATEX certified (CE Ex11 2GD X)
