This document discusses vacuum pump systems used in the production of aluminum beverage cans. It provides three case studies: 1) Rexam has used Pneumofore pumps for decades in their worldwide plants due to their low life cycle costs. 2) United Can in Jakarta replaced problematic screw compressors and pumps with Pneumofore's air-cooled systems to improve performance. 3) Vacuum is crucial for holding aluminum cans tightly during the shaping and packaging processes, and Pneumofore optimized production and energy savings for a major manufacturer in Spain.
