ARO® Air Operated Diaphragm Pumps
Everything You Need. Nothing You Don't
Air operated diaphragm 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 of the ARO®
diaphragm pumps are ATEX certified (CE Ex11 2GD X).
These 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 (1041 liter) per minute for our larger sizes and adjust fluid pressure up to 125 p.si. (8.6 bar), by using just an air filter / regulator and a needle valve.
