Volkmann pneumatic conveyors transport powder, dust, pigments, granulated material, tablets, capsules, small parts etc. in dilute, dense phase and plug flow conditions via a suction air stream under vacuum through hoses or pipes. Volkmann’s patented Multijector™ vacuum pump drives the system using a series of precision Venturi nozzles to increase the generated airflow from the air supply and to achieve a greater level of vacuum – as low as 28”Hg. For slower and denser material conveying, the pump lowers the conveyed velocity resulting in less risk of damage to the product, wear on the system or segregation of particles. The higher level of vacuum required for a plug flow situation is easily accommodated with the multi-stage Venturi found in Volkmann’s Multijector. Because of the vacuum created for the transfer, no product can escape into the environment if leakages occur. Leaks, should they occur, are always inwards leading to dust and emission-free operation, and safeguarding the work environment from explosions.
