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.

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.
