Safe Pneumatic Conveying of Powders and Small Particles
Volkmann Pneumatic Vacuum Conveyors bring damage-free, segregation-free pneumatic conveying solutions to the food, pharmaceutical, chemical and additive manufacturing industry.
Engineered and manufactured for ease of installation and simple operation, a Volkmann pneumatic conveyor is driven by a patented Multijector® pump to transport powders and bulk solid materials via high vacuum suction through conveying tubes. Working with negative pressure below atmospheric conditions, Volkmann pneumatic conveying systems contain transported product within the conveyor avoiding material escape into the environment and potential explosions.
Volkmann vacuum conveyors are constructed in a modular fashion and as a result, they can be adapted to the individual conveying task so that virtually all types of bulk materials can be conveyed. Powder and granules, tablets, pills, capsules, flakes, pellets and even larger pieces are pneumatically conveyed. There are even special solutions for “critical materials”, e.g. for wet, oily, adhesive, bridging, hygroscopic, poor-flowing and explosive materials. Even nanoparticles have been successfully transported pneumatically by vacuum.
Volkmann Pneumatic Vacuum Conveyors are ATEX Certified. They are capable of damage-free and segregation-free conveying of nano-sized material and fine dust from 0,1 µm up to larger sized tablets, candy or bottle caps. Even critical materials in dense phase conditions can be done safely and this vacuum conveying of powders can be adapted for use in hazardous applications inside explosion areas or with highly toxic materials. They are effective in dense phase as well as lean and plug flow conditions, offering pneumatic conveying of highly abrasive powders, mixtures, light filling materials, like fumed silica with only 0,05 kg/l bulk density, but work as well with metal powders with a bulk density of 10 kg/l such as those used in 3D printing and additive manufacturing.

Features of the Pharmaceutical (PPC) Vacuum Conveyors
These high quality, cGMP vacuum conveyors are used primarily by the pharmaceutical and color/lacquer industries. The PPC pneumatic vacuum conveyor features a one-piece, gap-free design for its separator elements that is completely electrical conductive. This design eliminates spaces where product might remain, and optimizes frequent product changes with easy, absolute cleaning of the process machinery to avoid product contamination and meet the highest quality standards. These powder conveying systems are easily dismantled without tools, can be cleaned quickly and can be sterilized – see how. A PPC Pneumatic Vacuum Conveyor is fitted with a large butterfly valve at the discharge. This, too, can be easily dismantled without tools.
PPC Pneumatic Vacuum Conveyors are offered as pre-configured units to suit the individual application. Customers can choose from a variety of pharmaceutical or electrical conductive filter systems (e.g. for hazardous inflammable materials). Special coatings, clamp modules, valve assemblies, WIP/CIP systems are available upon request.
