ARO

Air Operated Double Diaphragm Pumps

Air-operated double diaphragm pumps (AODD pumps) are ideal for general fluid transfer, moving a range of fluids from light to medium viscosity. Their design allows the transfer of large particles without causing any damage. With casings made of metallic or polypropylene, these pumps efficiently handle corrosive and abrasive substances. Many are also suitable for explosion-proof settings. Key benefits include:

  • Exceptional head and self-priming capabilities.
  • Efficient dry running.
  • Ability to operate without damage even when dead-headed.

Partnering with ARO, John Henry Foster ensures these pumps offer optimal flow rates with reduced pulsation and air consumption. The unique air valve design guarantees consistent, freeze-free operation. ARO pumps are not only reliable but also cost-effective for industrial applications. Their leak-free build prevents contamination and enhances user safety. Designed for durability, they undergo rigorous tests beyond typical use. These pumps can be customized in terms of flow rates, sizes, and material choices, ensuring a fit for various applications.
