Argal Astra Evo AODD DDE 650 ALN M DAD GLL Aluminium Casing Air Operated Double Diaphragm Pump

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

The Argal Astra Evo DDE 650 ALN is an ultra high-capacity air operated double diaphragm (AODD) pump engineered for large-scale industrial fluid transfer applications. Constructed with a robust aluminium casing, it provides excellent mechanical strength and durability for handling high volumes of fluids in demanding 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 ideal for hazardous and ATEX-rated installations.

Designed for extreme flow applications, the DDE 650 ALN is capable of handling solids up to 9 mm and offers a suction lift of up to 4.5 meters. Its very large displacement per cycle and high throughput make it suitable for bulk transfer and heavy-duty industrial processes.

This configuration supports multiple diaphragm material options, allowing flexibility for compatibility with a wide range of chemicals and applications.
