Ingersoll Rand ARO Operated Diaphragm Pumps

Air operated double diaphragm pumps are positive displacement pumps featuring two flexible, elastomer diaphragms. The pump uses compressed air to create a reciprocating action between the two diaphragms, creating a motion that pulls in and expels fluid through the pump chambers.

Air Operated Pumps for High Viscosity and Shear Sensitive Substances

Double diaphragm pumps work well for abrasive highly viscous substances such as oil, syrups, asphalt, and more and transfer shear sensitive substances and large particles without causing damage. The versatile pumping capabilities of air operated pumps makes them a popular option for applications including mining, paint and coatings, ceramics, chemicals, pulp and paper, oil and gas, and municipal/wastewater treatment.

The PVDF construction of ARO double diaphragm pumps provides excellent resistance to chemicals, minimizing wear and extending the life of your air operated pump. The pneumatic operation also makes air operated pumps safer to use around hazardous substances.

Benefits of air operated double diaphragm pumps include:

  • Virtually leak-free operation
  • Handles abrasive and highly viscous substances
  • Gentle pumping action for shear sensitive fluids
  • Runs dry without causing damage (dry running not recommended for long periods)
  • Self-priming for easier operation
  • Operate on compressed air instead of electricity
