Argal Astra Evo AODD DDE 160 WRN Y TPT GLL Polypropylene Casing Air Operated Double Diaphragm Pump

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

The Argal Astra Evo DDE 160 WRN is a high-capacity air operated double diaphragm (AODD) pump engineered for demanding industrial applications involving aggressive and corrosive fluids. Constructed with a polypropylene (PP) glass-reinforced casing, it offers excellent chemical resistance while maintaining strength and durability.

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

Designed for heavy-duty applications, the DDE 160 WRN is capable of handling solids up to 6 mm and provides a suction lift of up to 4.5 meters. Its large displacement per cycle and high flow capacity make it suitable for continuous operation in industrial processes.

This configuration features TPV + PTFE diaphragm combination, offering enhanced chemical resistance along with improved mechanical durability for aggressive fluid handling.
