From 2-circuit system to a 5-circuit system Background In an application concerning lifting of heavy glass sheets, a manufacturer of lifting equipment uses a profile system with a frame of aluminium with internal vacuum channels. Worn out suction cups causes dropping of glass sheets as the centralized vacuum system is unable to compensate for the leakage and loses its vacuum. Solution Due to the big volume that needed to be evacuated, the previous Classic pumps from Piab are replaced with two VGSTM 3010 units that are connected to each suction cup via a T-connector. Result The installation of VGSTM3010 units resulted in reduced compressed air consumption by 66%, from 14 Nl/sec to 4.7 Nl/sec. As the new system is decentralized, the glass sheets are no longer dropped, even if a suction cup o
