The vacuum system in Process Control’s showroom [Atlanta, GA] has recently been upgraded with a 10HP VF Series Vacuum Pump fitted with a variable speed drive. The drive has the ability to slow down or speed up the pump to match the conveying requirements for each vacuum receiver station. By controlling the speed, not only does the drive allow the user to save energy, but it helps keep the material undamaged during the conveying process. The pump can also be slowed down during idle time to further save energy. The conveying speeds are easily controlled through PCC’s Director Sequencing panel [as seen in the images below].

Great to see this handy article on the uses of VFDs!
