Ingersoll-Rand ARO Air Operated Diaphragm Pumps

Product Details:

Offered in multiple configurations, including single-post, two-post and heavy-duty two-post, our customizable packages ensure you have the right solution for a variety of piston pump applications, including oil and grease, paint and spray coatings, adhesives, sealants and much more.

Simply Versatile:
ARO piston pumps are capable of handling a wide variety of viscous fluids. With a wide selection of pressure ratios and displacement rates available, ARO offers a number of piston pump packages that can meet your specific application needs. Offered in multiple configurations, including single-post, two-post and heavy-duty two-post, our piston pump packages ensure you have the right solutions for the following applications as well as many others.

2-ball pumps are among the most versatile in the ARO® line. They are capable of handling applications from simple transfer to the extrusion of low- to medium-
viscosity materials up to 100,000 centipoise (cPs) with fluiddelivery up to 18.1 gpm (68.6 L/min). 

Applications advantages of 2-balls:

• Spray: 2-ball pumps deliver the constant flow rate and pressure needed for consistent and efficient coatings applications
• Transfer & Supply: Depending on the model, some 2-ball pumps can achieve flow rates up to 18.1 gpm, providing dependable results
• Extrusion: 2-ball pumps generate pressure to handle extrusion of low-to medium-viscosity 
• Lubrication:  ARO® 2-balls pumps provide the flow and pressure required for moving light oils and grease lubricants
• High Pressure Cleaning: ARO® Wash Pump Packages are portable and offer the the right option for industrial cleaning applications.

• Materials advantages of 2-balls:

  • Sheer sensitive materials: ARO® 2-ball pumps minimize friction points to prevent fluid shear, when compared to other similar pumping technologies
  • Abrasive and high solid materials: ARO 2-ball pump minimize friction points and allow smooth passages to maintain fluid consistency
  • Optional ceramic coating provides an even
    stronger defense against highly abrasive fluids like paint and glass-filled sealer.

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

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*

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.
