Air Operated Diaphragm Pumps


Ideal for Abrasion and Solids Handling because they don't use rotating, sliding seals, process engineers look to ARO diaphragm pumps for handling tough abrasion applications.
Bolted Construction for Safe Reliability and Ease of Assembly.
All ARO diaphragm pumps use a bolted construction and ARO non-metallic pumps utilise fasteners that are constructed of 300 series stainless steel for maximum chemical resistance.


  • Safer - Bolted construction reduces the risk of spills and environmental contamination.
  • Reliable - Bolted construction withstands the heavy loading that diaphragm pumps are subjected to.
  • Easier to Assemble - ARO's bolted design allows for easy positioning and alignment of parts during reassembly.
  • Less expensive - ARO's design uses standard bolts which cost significantly less to replace
