Air operated diaphragm pumps

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.

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.

All ARO pumps are available with convoluted diaphragms offering long product life and reduced maintenance. Metallic Materials:

Aluminium

• Cast Iron 
• Stainless Steel 
• Hastelloy 

Non-Metallic Materials:

• Polypropylene 
• Acetal 
• EXP is Automation Ready 

All EXP Series pumps are enhanced with electronic interface capability, providing accurate, electronically controlled dosing. Combine our pump with the ARO Controller or a PLC or PC based system and switch from inaccurate, inefficient manual processes to intelligent fluid management. Ol
