Argal Astra Evo AODD DDE 650 WRN M DPD GLL 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. Constructed with a polypropylene (PP) glass-reinforced casing, it offers excellent chemical resistance while maintaining strength and durability in harsh operating environments.

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

Designed for heavy-duty operation, the DDE 650 WRN is capable of handling solids up to 9 mm and provides a suction lift of up to 4.5 meters. Its very large displacement per cycle and high flow capability make it ideal for bulk transfer and continuous industrial processes.

This configuration features a TPV diaphragm setup, delivering strong chemical compatibility and durability across a wide range of fluid handling applications.
