Argal Astra Evo AODD DDE 650 WRN M DZD ALL Polypropylene Casing Air Operated Double Diaphragm Pump

Ultra high capacity air operated diaphragm pump, polypropylene AODD pump, industrial chemical transfer pump, heavy-duty fluid handling solution

The Argal Astra Evo DDE 650 WRN is an ultra high-capacity air operated double diaphragm (AODD) pump designed for large-scale industrial fluid transfer applications. Built with a polypropylene (PP) glass-reinforced casing, it provides excellent chemical resistance while maintaining durability in aggressive operating environments.

Operating on a 1:1 pressure ratio, the pump is powered entirely by compressed air, ensuring safe and reliable operation without electrical components. This makes it suitable for hazardous and ATEX-rated installations.

Engineered for heavy-duty performance, the DDE 650 WRN can handle solids up to 9 mm and offers a suction lift of up to 4.5 meters. Its very large displacement per cycle ensures efficient high-volume transfer, making it ideal for continuous industrial processes.

This configuration supports advanced diaphragm material combinations, enabling compatibility across a wide range of chemicals and fluid handling requirements.
