Explore the ARO-Flo Series by Ingersoll Rand, setting new standards in safety, performance, and modularity for air filtration systems. Discover how ARO FRLs optimize your operations with integrated safety features, exceptional flow performance, and easy modularity.

The ARO-Flo Series by Ingersoll Rand continue the tradition of offering premium products for your operation, and also raises the bar in the industry for safety, flow performance, and modularity.

Safety
ARO-Flo Series FRLs are designed with integrated safety features such as locking bowls and clear multilingual markings. Accessories such as lockout valves, check valves, and soft-start valves allow the air supply to be safely managed and controlled.

Performance
ARO-Flo filters, regulators, and lubricators FRLs perform better than almost any other air filtration device. This means less air is choked during the air preparation process, and your equipment can perform at its peak performance.

Modularity
All ARO-Flo accessories are designed to integrate with each other within each size range. From pipe adapters to T-brackets, your complete FRL assembly and its individual components can be easily, safely, and quickly assembled or disassembled with a minimum of tools — no fuss or complications, even with fixed piping.

ARO diaphragm pumps are built to thrive in harsh conditions, offering ruggedness and reliability that stands out in the industry. Engineered for maximum flow rates with minimal pulsation and air consumption, these pumps are designed to endure even the toughest environments.

Our patented unbalanced air valve design ensures stall-free and ice-free operation, making ARO diaphragm pumps suitable for potentially explosive areas. The bolted, leak-free construction enhances safety by eliminating cross-contamination.

With modular construction and easy-to-use repair kits, ARO diaphragm pumps minimize repair time and cost, ensuring efficient operation. We rigorously test our pumps to exceed industrial standards, guaranteeing long-lasting performance.

Tailored to Your Application
ARO diaphragm pumps offer versatility with various flow rates and sizes, allowing you to adjust the flow outlet and discharge pressure according to your needs. From low-flow applications to larger pump sizes handling high volumes, ARO pumps deliver consistent performance.

Rugged and Reliable in Harsh Conditions.

ARO diaphragm pumps are expertly engineered to go the distance, even in the harshest environment.

These pumps feature maximized flow rates with minimized pulsation and air consumption. ARO’s patented unbalanced air valve design ensures stall-free, ice-free operation. Due to their pneumatic motor, ARO’s diaphragm pumps could be used in potentially explosive areas.

ARO’s diaphragm pumps are a reliable, cost-effective choice for industrial and chemical applications. The bolted, leak-free construction eliminates cross-contamination and increases operator safety. Modular construction, reduced parts count and easy-to-use repair kits minimize repair time and cost.

These pumps are rigorously tested — far beyond typical industrial use — to ensure that your diaphragm pump is built to last.

Diaphragm Pumps Tailored to Your Application

ARO diaphragm pumps are available with many flow rates and sizes, allowing you to vary the flow outlet and discharge pressure. These 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.
