Air Operated Double Diaphragm Pumps (AODD)
- Air-operated diaphragm pumps use compressed air to operate (no electricity required)
- Different body materials are available (aluminum, polypropylene, stainless steel), suitable for basically all types of fluids, including corrosive liquids and liquids with high solid content.
- The air motor of the pump can work in danger zones and areas vulnerable to explosion (Explosion Proof)
- The Air motor incorporates a no stall air valve for reliable start-up
- Can replace diaphragm pumps from other manufacturers such as Wilden, Graco, Yamada, Versamatic and Aro-Ingersoll Rand
