Diaphragm Pumps / Ingersoll Rand Aro by Hydraulics & Pneumatics Engineers

For over 85 years, the ARO® Fluid Products business of Ingersoll Rand has developed partnerships with more than 200 original equipment manufacturers and distributors, enabling us to better focus on the unique pumping needs of many industries. It’s a strategic merger of our partners’ application expertise, along with our decades-long legacy of designing and building outstanding piston pumps.

Why ARO Diaphragm Pumps?

Go to Products

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

• ARO Diaphragm Pumps provide stall-free, ice-free operation.
• Patented “Unstallable” unbalanced air valve design avoids stalling issues associated with other pumps.
• “Quick-Dump” exhaust valves divert cold exhaust air from ice-prone components, preventing freezing.
• Backed by a five-year warranty, we have the most reliable pump line on the market today.
