About Aro

ARO's catalogue includes pumps, motors, valves, air regulators, pneumatic lubricators, solenoid coil connectors and compressed air filters. The brand's double diaphragm pumps are positive displacement pumps that run on compressed air to move highly viscous solvents & slurries in wet commercial pumping applications. These ARO pumps feature aluminium / cast iron / stainless steel / polypropylene / acetal / kynar body construction to ensure low friction and corrosion resistance on exposed surfaces. These ARO pumps have a maximum flow rate of 237 gpm, are offered in flanged / NPT connections and can be operated at temperatures up to 200 degrees F. ARO 3 way, 2 position solenoid air control valves are used in hydraulic systems and fluid power pneumatic services for controlling fluid power motors and cylinders valves. These ARO pump valves are prelubed and are capable of being operated without air line lubrication. They come equipped with a junction box having gaskets and moulded connectors to protect electrical connections (lead wire / DIN connectors). These ARO pump valves have a maximum volume coefficient of 4.32, feature a ported body to reduce the force applied to the valve and can withstand a maximum pressure of 150 psi. These ARO solenoid air control valves deliver flow rates up to 150 cfm and can be operated at temperatures ranging from -10 to 180 degrees F. Choose from a wide range of these ARO pumps and valves, along with solenoid valve manifold accessories, on Raptor Supplies, a trusted ARO pump distributor.

Things To Consider

Cross-Reference Alternatives

Some ARO items cross individual references to the equivalent Speedaire, Parker or Milton Industries model numbers. So, if you're looking for a competitor motor that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent ARO product available.

Why Us?

Raptor Supplies, a US industrial parts distributor, can recommend suitable products for targeted applications in ceramic, marine, manufacturing and food & beverage processes.


These ARO pumps range from small to large sizes. They may require careful packaging as some items may get damaged while shipping. Hence, these ARO pumps are delivered by courier shipment and air freight for minimum downtime.

Aro Competitive Advantages

AFX Technology Based Pumps

AFX technology based ARO pumps feature Progressive Exhaust parabolic valve geometry ensuring high flow capacity. They have cascading expansion chambers for eliminating changes in pump performance caused by icing or changing environmental conditions. The lubrication free operation of these pumps helps in reducing lubricating costs and the 6 inch stroke improves the pump's performance with improved pulse profile, high displacement per stroke and reliability due to negligible switchovers per cycle. They are equipped with a fibre wound, composite & conductive cylinder with epoxy coating for wear resistance. They have actuation control ports to provide access for pneumatic logic signal controls.

Frequently Asked Questions

How does an ARO pump work?

ARO pumps have two pumping chambers that are alternately filled and discharged by the flexible diaphragm movement. Compressed air is also alternately blown to and discharged from air chambers on the opposite sides of the pump's diaphragms for creating the pumping action.

Is ARO associated with Ingersoll Rand?

ARO is a subsidiary brand of Ingersoll Rand, which has been a pioneer in air compressor systems, power tools and hand tools for more than 100 years.

Does a diaphragm pump need to be primed?

Diaphragm pumps are self priming and are suitable for viscous slurries & solvents.

Do diaphragm pumps need lubrication?

Air operated diaphragm pumps are rugged and lube free pumps. They provide high quality, hassle free & continuous output, even under the harshest conditions.

What is a double diaphragm pump?

A double diaphragm is a positive displacement pump that utilises two flexible diaphragms reciprocating back & forth, making a temporary chamber, which both draws in and discharges fluid through the pump. The diaphragm acts as a separation wall between the liquid and air.
