Argal Astra Evo AODD DDE 400 WRN Y TPT GLL Polypropylene Casing Air Operated Double Diaphragm Pump

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

The Argal Astra Evo DDE 400 WRN is an ultra high-capacity air operated double diaphragm (AODD) pump engineered for heavy-duty industrial applications involving aggressive and corrosive fluids. Built with a polypropylene (PP) glass-reinforced casing, it delivers excellent chemical resistance while maintaining strength and durability in demanding environments.

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

Designed for large-scale fluid transfer, the DDE 400 WRN is capable of handling solids up to 7 mm and provides a suction lift of up to 4.5 meters. Its large volume per cycle and high flow capacity make it suitable for continuous, high-demand industrial processes.

This configuration features TPV + PTFE diaphragm combination, providing enhanced chemical resistance and improved durability when handling aggressive fluids.
