Volkmann is showcasing new variants of their highly successful VS series of vacuum conveyors featuring electric pump options this week at PACK EXPO 2012 in Chicago. These new pump options mount a purpose-designed Electric Switch Box Assembly (EPV) directly on the receiver. Because the EPV includes a non-return valve and vacuum relief valve as standard, the unit can be coupled to any electrically driven vacuum pump assembly, providing greater flexibility for end users. Volkmann is also displaying a new PLC-based controller, the QX “quick exchange” patented filter system and a full range of Multijector® compressed air driven working conveyors. Booth #E-7658.
