Engineered for total reliability in your most critical processes, GemmeCotti AODD air-operated double diaphragm pumps are the definitive solution for demanding fluid transfer. They are specifically designed to handle challenging fluids, from aggressive chemicals to liquids with very high viscosity and suspended solids. At the heart of each AODD pump is an advanced anti-stalling pneumatic circuit that ensures constant, efficient operation without the need for lubricated air. This robust design guarantees superior operational reliability, allowing the pumps to run dry for extended periods without damage and operate against a closed discharge, protecting your entire system. To ensure complete chemical compatibility, the HAOD series is available in a wide selection of materials, including Polypropylene, PVDF, and AISI 316 stainless steel. Furthermore, their intrinsic safety is confirmed by the availability of a certified ATEX version, making them the ideal choice for operating in potentially explosive atmospheres.
