ARO PRO Air Diaphragm Pump – 1″, Aluminium/Nitrile, ATEX Rated

The ARO PRO Series diaphragm pump, designed for tough industrial applications, delivers powerful performance with exceptional efficiency. This 1″ metallic pump features an aluminium body and nitrile (NBR) diaphragms, therefore making it ideal for demanding environments where reliability is key. With a maximum flow of up to 133 LPM (35 GPM), this air diaphragm pump is engineered to handle fluid transfer, recirculation and also batch dispensing tasks. The ARO PRO Series is a versatile performer, perfect for manufacturing and chemical processing applications, delivering high flow and discharge pressure even under tough conditions. Unique design features ensure minimal pulsation and low maintenance, consequently reducing downtime and life-cycle cost.

ARO PRO Series diaphragm pumps are designed for best-in-class reliability and performance. They are optimised to maintain separation between wetted fluid handling components and air-side components. As a result, contamination risk in reduced, along with frequency of repairs, making it a cost-effective and reliable choice for demanding applications.

The pump excels in handling abrasive and viscous fluids, such as sludges and slurries, due to its high-clearance check valve design. Furthermore, the pump delivers consistent flow even with challenging materials. Additionally, the pump’s smooth operation makes it ideal for shear-sensitive fluids, where minimising mechanical stress on the fluid is crucial to preserving its integrity.

Designed to operate in hazardous Ex-Zoned environments, this ARO air diaphragm pump is suitable for use in areas where flammable vapours are present, such as petrochemical plants, gas handling stations and fuel transfer facilities.

With stationary seals located only between the wetted components and the external environment, the risk of leakage is consequently limited. Leakage can only occur if one or both of the diaphragms fail, which further reduces operational risks associated with the pump.

his 1″ ARO PRO diaphragm pump is ideal for:

Oil and diesel transfer

Chemical dosing and batching

Ethanol and also detergent applications

Recirculation and filling systems

Any process requiring an air diaphragm pump with explosion-proof capability

This ARO PRO diaphragm pump is equivalent to the Flux FDM 25 AL/NN, providing the same performance, high-quality and reliability backed by ARO’s trusted engineering expertise.
