A favorite of process professionals everywhere- Ingersoll Rand / ARO Air Operated Diaphragm Pumps provide stall-free, ice-free operation in 3/8” thru 3” fluid ports. Backed by a five-year warranty, there are the most reliable pump line on the market today.
Why ARO diaphragm pumps?
- Sealless Design
- Low Material Shear
- Ease of Maintenance
- Can Run Dry Without Damage
The ARO range of diaphragm pumps offers many materials of construction.
All ARO pumps are available with convoluted diaphragms offering long product life and reduced maintenance.
ARO’s FDA-compliant pumps, a part of our Expert Series (EXP) line, are designed to transfer fluid for the food and beverage industries efficiently and safely. Our pumps typically yield 20 to 30 percent better flow rates than other products available on the market, ensuring the material is transferred carefully. Since every ounce of fluid is treated gently, the shelf life is often extended and product quality maintained.
All ARO® EXP pumps feature:
???Patented “Unstallable” unbalanced air valve design which avoids stalling issues associated with other pumps.
???Exhaust valves that divert cold exhaust air from ice-prone components, which prevents freezing and downtime.
???Ability to pass even large shear-sensitive solids without degradation or heat build-up.
???The ability to run dry (eliminating the risk of pump damage).
???Gentle pumping action will not froth or separate fluid, improving end-product quality.
Certification: ARO® FDA Compliant pumps are engineered to the meet the highest standards and requirements in the industry including: CE, ATEX, 1935/2004/EC and FDA CFR 21.177

Receiving and Unloading:
Utilizing technology identical to other ARO Pumps, these Specialty models will provide the same high level of performance and satisfaction but in a design tailored for your specific application. Specialty pumps include: Drum Packages, Flap Valve pumps, Powder Transfer pumps, High Pressure pumps, Sanitary Transfer pumps, Centrifugal De-watering pumps, and Fuel Pumps.
ARO® EXP Series diaphragm pumps include all the benefits of standard air-operating pumps, but with significant additional features and benefits.
- Electronic Interface capability and solenoid actuation allow for accurate cycle rate control and more consistent volume per stroke. Our solenoid control also ensures a precise number of cycles to be fully completed for improved batch repeatability.
- Patented SimulShift™ “unstallable” air balanced valve design which avoids stalling issues associated with other pumps
- Quick Dump™ check valves that divert cold exhaust air from ice-prone components, which prevents freezing downtime
- Available with Long-life PTFE diaphragms, providing 2 time increase in service life over standard PTFE*
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.
