Argal Astra Evo AODD DDE 400 SPN Y TST CFB 316L Casing Air Operated Double Diaphragm Pump

Ultra high capacity stainless steel diaphragm pump, hygienic AODD pump, 316L industrial transfer pump, air operated fluid handling system

The Argal Astra Evo DDE 400 SPN is an ultra high-capacity air operated double diaphragm (AODD) pump designed for the most demanding industrial and hygienic fluid transfer applications. Featuring an electropolished AISI 316L stainless steel casing, it provides exceptional corrosion resistance and is ideal for pharmaceutical, food, and aggressive chemical 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 with large 2" clamp (tri-clover) connections, the pump enables high-volume transfer while maintaining hygienic standards and easy maintenance. It is capable of handling solids up to 7 mm and provides a suction lift of up to 4.5 meters, making it suitable for heavy-duty and high-flow applications.

Equipped with TPE + PTFE diaphragms, the pump delivers excellent chemical resistance and durability, especially in aggressive and high-purity fluid handling processes.
