ARO Air operated Diaphragm Pumps


ARO Pro Series air operated diaphragm pumps are ideal for general industrial and OEM installation applications.

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 of the ARO diaphragm pumps are ATEX certifed (CE Ex11 2GD X).

Our pumps offer the ability to vary the flow outlet and discharge pressure as slow as 0.26 gallons (1liter) per

minute up to 275 gallons (1040 liter) per minute for our larger sizes and adjust fluid pressure up to 123 p.si.

(8.5 bar), by using just an air filter regulator and a needle valve.
