Five vacuum pumps model UV30 from the year 2000 with 130.000 hours of operation were replaced with three new pumps model UV50 VS90. The new vacuum system was commissioned in January 2017. The control system follows latest standards for the optimized operation of the three frequency-drive equipped UV50 pumps. Two UV50 VS90 units with the total capacity of 6.500 m3/h cover the vacuum flow request from production; one UV50 VS90 unit is in stand-by. The previous four UV30 pumps are returned to Pneumofore for the total overhaul with a full refurbishment and resale. The collaboration of Pneumofore with the present Ball Group goes back to 1983, to the times of the first American National Can factories in Italy, later NACANCO, later Rexam plants.
