Air Operated Diaphragm Pumps

Air Operated Diaphragm Pumps operate substantially different from conventional Electrically driven centrifugal or Positive Displacement Pumps. These differences can make the AOD the most cost effective solution to your most difficult pumping solutions.

Our AOD* live is available in 7 sizes from ¼" to 3" in Aluminium, Cast iron, Stainless Steel, Polypropylene, and PVDF. Elastomers include Neoprene, Bune-N, Viton*, Teflon*, Santoprene*, and Nordel*.

Benefits

  • Handles the widest variety of fluids of any single type of Pump. High Viscosity liquids that can't be handled by centrifugal pumps, low viscosity liquids that can't be handled by other PD pumps.
  • Infinitely variable flow rate up to 52m2/hr with maximum air inlet press of 125psi.
  • Self – Priming – the AOD* can be mounted above or below liquid level – even submerged.
  • It can operate against a closed discharge. This makes AODs* an excellent choice for bulk dispensing, batching or feeding a pressurised system.
  • Runs dry without damage to the pump or piping system, making the AOD suited for transfer applications, emptying tanks and dewatering.
  • Uses compressed air – inherently explosion proof. No Dynamic electrical components to spark. No heat generating components.
  • Handles shear sensitive or fragile liquids like paint, ink and Clay.
  • Does not require complex controls or expensive auxiliary equipment to install and operate.
