In substitution of the traditional centrifugal pumps with electric motor, the users of a zoo technical plant for the production of animal food have chosen a high-efficient air-operated double diaphragm made by ARGALAIR for pumping acid products. Made of AISI 316L and Teflon, the ASTRAevo DDE 100 pump transfers a mix of additives at ambient temperature. 

The various functionalities of the ASTRAevo AODD pump guarantee significant improvements compared to the centrifugal pumps: run-dry (when the tank is empty), self-prime (negative suction head), frequent start and stop, easy installation and maintenance, low maintenance costs, and above all, the selection of materials highly resistant to strongly corrosive acids.
