BMG’s ARO Pro series air-operated diaphragm pumps

 BMG’s ARO air-operated diaphragm pumps have been designed to pump virtually any type of liquid with ease - ranging from clean, light to medium viscosity fluids, to highly corrosive and abrasive fluids. ARO pumps can also transfer large particles without damaging the pump. 

BMG was appointed by Ingersoll Rand at the end of 2018, as distributors of the ARO® Pro series diaphragm pumps.

“ARO air-operated diaphragm pumps have been designed to pump virtually any type of liquid with ease – ranging from clean, light to medium viscosity fluids, to highly corrosive and abrasive fluids. ARO pumps can also transfer large particles without damaging the pump,” explains Joe Pinheiro, BMG’s National Product Manager, Pumps. “This range is suitable for general industrial and OEM installation applications in diverse industries, including chemical and petrochemical, manufacturing, energy, pharmaceutical, mining, oil and gas and water and wastewater sectors.

“Notable features include a seal-less, self-priming design, with low material shear and minimal maintenance requirements. These portable pumps are easy-to-install and can run dry without damage. Most ARO diaphragm pumps are ATEX certified (CE Ex11 2GD X) enabling safe use in potentially explosive areas. This feature makes the ARO pumps ideal for underground applications, such as dewatering.”

ARO Pro series air-operated diaphragm pump air motors, which are lubrication-free, have positive sealing characteristics and make use of a specially-designed unbalanced airvalve to prevent stalling issues associated with operation at low pressures. Exhaust valves divert cold airaway from components that are prone to ice build-up.

ARO pumps allow users to vary the flow outlet and discharge pressure as low as 1 litre per minute, up to 1 040 litres per minute for larger sizes and to adjust fluid pressure up to 123psi (8.5 bar) by using an air filter/regulator and a needle valve.

Metallic and non-metallic air-operated diaphragm pumps are available from BMG in various materials and porting configurations to suit numerous applications, including transfer, loading/unloading/filling, re-circulation, system flushing and batching/blending in many industries.

ARO metallic diaphragm pumps are manufactured in Aluminium, Stainless Steel, Cast Iron and Hastelloy, while non-metallic units are available in Polypropylene, Acetal and PVDF. A full range of internal materials, such as Nitrile, Santoprene, PTFE, Hytrel and Neoprene are also offered.

A range of speciality pumps is also available from BMG, including Stainless Steel sanitary pumps (FDA approved), 3:1 highpressure pumps, submersible diaphragm pumps, air driven submersible pumps, anti-freeze blending pumps and UL-approved fuel transfer pumps.

All ARO fluid handling products have been engineered to deliver performance and serviceability, enabling users to achieve the best total cost of ownership.

BMG supports this range with a technical advisory service to ensure the selection of the most suitable pump for every application. The company also supplies a full range of ARO diaphragm pump parts and accessories for standard repair and maintenance requirements.
