Air-operated diaphragm pumps are designed for general use. They can easily pump anything from clean, low-viscosity liquids to corrosive and abrasive medium-viscosity fluids, as well as transport large particles without damage. Thanks to their air motor, they can be used in potentially explosive areas. Most ARO® diaphragm pumps are ATEX certified (CE Ex11 2GD X).

These pumps allow you to vary the output flow from as little as 1 liter (0.26 gallons) per minute to 1041 l (275 gallons) per minute on the larger pumps, as well as vary the fluid pressure up to 8.6 bar (125 psi ) with only one air filter/regulator and one needle valve.
