How ARO air operated double diaphragm pumps are used in wastewater treatment

ARO’s full range of mobile pump solutions for water and wastewater applications are built for tough jobs. When you need a reliable, cost-effective pump for handling and transferring fluids with high solids content, you can count on ARO.

Because wastewater can be highly abrasive and chemically aggressive, ARO diaphragm water pumps are designed to outperform the competition. They provide a more robust seal than electric pumps, which rely on mechanical seals that can leak and cause hazards.

Water & Wastewater Applications:

  • Dewatering through filtration (filter press)
  • Chemical dosing to neutralise pH levels and treat sludge
  • Wastewater sump transfer and sample
  • Municipal water treatment plants, wastewater treatment plants and utility pumps
  • Belt press feed
  • Sewage treatment process
  • Potable water systems

Features & benefits of an AODD pump:

Safety: AODD pumping systems with leak-free, stall-free capability ensure safety.

Versatile and Flexible: AODD pumps are compatible with a broad range of chemicals. Pumps can be cleaned and moved between processes, and one pump can be used for numerous applications.

Productivity: ARO’s EXP Series diaphragm pumps have optional integrated electronic interface features. Leak Detection, End-of-Stroke and Solenoid Controlled Operation help manufacturers aggregate data to increase productivity and reduce downtime.

  • Long-lasting diaphragms to minimise downtime and exposure to potential safety hazards.
  • Reliable pressure and greater flow control.
  • Portable and self-priming for quick-start operations.
  • Chemical resistant pumps available in stainless steel, polypropylene, PVDF and conductive poly.
