Advantages of ARO® double diaphragm pumps from the EXP series:

  • The ability to automate these pumps with virtually any automation system (ARO controller, PLC- or PC-based system) through the use of an electronic interface allows you to turn imprecise, manual processes into efficient and intelligent liquid management.
  • Optional leak sensors detect diaphragm failure and minimise costly downtimes
  • Patented SimulShift™ design of symmetric air valves for start-up safety, to avoid problems with starting up in conjunction with other pumps
  • Quick Dump™ check valves are used to remove cold exhaust air from components prone to icing over to prevent icing and failure
  • With service lives four times the length of other manufacturers on the market, downtimes are reduced
  • Simple and speedy repairs thanks to low-cost service kits
  • Available for use in hazard zones (ATEX, NEC and CEC certificates)

The diaphragm pumps from the EXP series are available in the following materials

Non-metallic materials Polypropylene, Acetal and PVDF
