Argal Astra Evo AODD DDE 160 SPN Y TST CLL 316L Casing Air Operated Double Diaphragm Pump

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

The Argal Astra Evo DDE 160 SPN is a high-capacity air operated double diaphragm (AODD) pump engineered for demanding hygienic and industrial applications. Featuring an electropolished AISI 316L stainless steel casing, it provides exceptional corrosion resistance and is ideal for pharmaceutical, food, and aggressive chemical environments.

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

Designed with hygienic clamp (tri-clover) connections, the pump enables easy installation, maintenance, and cleaning. It is capable of handling solids up to 6 mm and provides a suction lift of up to 4.5 meters, making it suitable for high-demand fluid transfer applications.

Equipped with TPE + PTFE diaphragms, the pump delivers excellent chemical resistance and durability, especially in applications involving aggressive and high-purity fluids.
