ARO® air-operated diaphragm pumps
Double-diaphragm pumps from ARO®. PRO, EXPERT and FDA series, plus special pumps
The compressed air-driven diaphragm pumps from ARO® provide a flexible solution for pumping products ranging from clean, slightly viscous materials to corrosive, abrasive, medium-viscosity media as well as coarse-grained solids. You stand to gain from industry-leading efficiency, reliability and tried-and-tested performance. All ARO® double diaphragm pumps are available with folded diaphragms, delivering longevity and less maintenance.
ARO® also supplies a large choice of very varied materials, connections and versions with FDA approval for hygiene applications and ATEX certification for areas protected against explosion (CE Ex II 2GD X).
We also supply a large choice of special pumps, such as powder pumps, high-pressure pumps, pumps with flap valves and an extensive range of accessories.
- Seal-free construction
- Gentle transfer of liquids
- Little material wear
- Ability to run dry for short periods
- Mobile use
- Simple installation
The pumps stand for maximum performance, through a maximized throughput in combination with minimal pulsation with low air consumption.
The pumps can be specially adapted to your applications through many connection options.
The pumps offer reliable, carefree operation thanks to the lubrication-free, patented differential valve, both on the main air valve and on the SimulShift (pilot valve) and at any time "Fluid On Demand" (liquid on request.
The pumps offer maximum chemical resistance and leakage protection thanks to the screw construction in conjunction with a large number of material options.
The pumps minimize repair times and costs through a simple modular structure, fewer components and easy-to-use repair kits.
The double diaphragm pumps from ARO® are available in metallic and non-metallic materials:
|Non-metallic materials||Polypropylene, conductive Polypropylene, Acetal, PVDF and conductive PVDF|
|Metallic materials||Aluminium, Cast iron, Stainless steel and Hastelloy|
The patented ARO® air motor technology:
- SimulShift ™ valve:
Prevents the pumps from coming to a standstill - enables faster switching with larger flow rates.
- Unbalanced” main air valve:
No pump downtime even with low inlet air pressures.
- “D” valve for optimum energy efficiency while avoiding costly “compressed air losses”. Ceramic construction for a long service life.
- Quick Dump™ Exhaust Valves:
Prevent pump freezing by diverting cold and humid exhaust air from the main air valve.
