Air-operated diaphragm pumps

Third Quarter 2019 Pneumatic systems & components

BMG has been appointed by Ingersoll Rand 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 viscosity fluids, to highly corrosive and abrasive fluids. They can also transfer large particles without damaging the pump. This range is suitable for general industrial and OEM installation applications in diverse industries, including chemical and petrochemical, energy, pharmaceutical, mining, oil and gas, and water and wastewater.

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 them 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 air valve to prevent stalling issues associated with operation at low pressures. Exhaust valves divert cold air away from components that are prone to ice build-up.

ARO pumps allow users to vary the flow outlet and discharge pressure from 1 litre per minute, up to 1040 litres per minute for larger sizes and to adjust fluid pressure up to 8.5 bar using an air filter/regulator and a needle valve. Metallic and non-metallic air-operated diaphragm pumps are available in various materials and porting configurations to suit numerous applications, including transfer, loading/unloading/filling, re-circulation, system flushing and batching/blending.
