ARO
Pneumatic Diaphragm Pumps
Tailored to Your Application
ARO double diaphragm pumps are available with many flow rates and sizes, allowing you to vary the flow outlet and discharge pressure. Our pumps can run as slow as 0.26 gallons (1 liter) per minute and up to 275 gallons (1079 liters) per minute for larger pump sizes.
Adjust fluid pressure up to 125 p.si. (8.6 bar) by using an air filter/regulator and a needle valve.
Each ARO pneumatic pump can be customized for your fluid transfer needs. Choose from a wide range of diaphragm materials, casing options and accessories. Find metal or plastic fluid sections that can handle any fluid, including corrosives and abrasive.
ARO EXP
Featuring flow rates up to 285 GPM (1079 l/min) ARO EXP diaphragm pumps offer a wide range of material and porting configurations. EXP Series pumps are available with Electronic Interface capability, solenoid actuation for accurate cycle rate control, and long-life PTFE diaphragms, providing a 2-time increase in service life over standard PTFE*.
ARO PRO Series
PRO Series diaphragm pumps offer the ability to vary the flow outlet and discharge pressure as low as 0.26 gallons (1 liter) 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.
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 ARO diaphragm pumps are ATEX certified.
