Argal Astra Evo AODD DDE 100 SPN Y TST CLL 316L Casing Air Operated Double Diaphragm Pump

Stainless steel diaphragm pump, hygienic AODD pump, 316L chemical transfer pump, air operated industrial pump

The Argal Astra Evo DDE 100 SPN is a high-capacity air operated double diaphragm (AODD) pump designed for demanding hygienic and industrial fluid transfer applications. Featuring an electropolished AISI 316L stainless steel casing, it offers 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 operation without electrical components. This makes it suitable for hazardous and ATEX-rated environments.

Designed with hygienic clamp (tri-clover) connections, this model enables easy installation, maintenance, and cleaning, making it perfect for sanitary processes. It is capable of handling solids up to 5.5 mm and provides a suction lift of up to 4 meters.

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