Reliability issues and related downtime were eliminated and overall pump productivity jumped by more than 75% –T. J. Harris, Maintenance Mgr. DMS

ARO is introducing the world’s first closed-loop controller for air-operated diaphragm pumps. Building on years of innovation and technical expertise, ARO is responding to customer needs for a closed-loop system that allows them to customize production lines and remotely monitor fluid transfer to ensure greater efficiency and less production downtime. With the ARO Controller, ARO proactively solves some of industry’s most challenging fluid management issues while providing a solution that is easily integrated into existing production lines.


Traditional control systems rely upon a series of manual processes that require the attention of an operator or multiple operators along a plant line. In contrast, a closed-loop controller allows customers to remotely take control of batching and monitoring fluid transfer with an ease of use that reduces errors and lowers costs.


From mixing chemicals to cleaning water to combining fluids and beyond, smart, efficient air control systems touch a variety of industries throughout the world, including:

  • Chemical processing
  • Paint/ink/coatings
  • Waste water treatment
  • Agriculture
  • Car wash dispensers
  • Ceramics
  • Electronics
  • Dry cleaning
  • Nuclear power
  • Pet food
  • Pharmaceutical
  • Printing
  • Pulp and paper
