 The advanced vacuum conveyors—when used with a level-controlled buffer hopper—safely transport powders, granules, pellets, capsules, tablets and other bulk materials under vacuum. This transport can supply packaging lines, mixers, filling machines, tablet presses or any other kind of process equipment or vessel, such as, containers or silos on demand. This interactive, enclosed transfer system has considerable advantages over conventional mechanical transport technologies most notably in the transfer of traditionally difficult and sensitive powders. The cyclic vacuum plug flow conveying arrangement of the conveyors avoids product separation or segregation. In addition, building on the available European ATEX explosion safety certificates for all vacuum conveyors, the units are the perfect choice for potential explosion-proof areas for powders and gases, according to the manufacturer. The company is the first vacuum conveyor manufacturer to receive this certification, a useful advantage to the market now faced with tightening OSHA requirements.

The clearance-seated butterfly valves are primarily intended for use in handling dry plastic pellets. The valve is available in ANSI Class 150 lugged body, sizes 4- to 12-inch.
