Vacuum pump for pneumatic conveying
max. 177 m³/h, 6 bar | PVR series VUOTOTECNICA

Working principle
The operation of these vacuum generators is based on the Venturi principle.
Unlike the previous ones, the ejector, apart from having a much larger flow diameter, is also adjustable.
This feature allows modifying the capacity and the vacuum level of the device, without intervening on the air supply pressure level. Also the compressed air consumption is related to the actual performance of the vacuum generator.
Features
The special shape of these adjustable vacuum generators, as well as their straight-flow working principle allow sucking and transferring products of various nature with no interference, just like flow generators, only, unlike these, they allow overcoming much higher level differences.
They are suited for transferring powders, granulated products, sawdust, metal chips, dry or liquid food products, etc.They are also recommended for controlling vacuum cups in presence of large amounts of dust or liquids, as well as for sucking fumes, cooling mists, water and oil condensation, etc. The absence of moving parts allows for a continuous use without developing heat. The noise level, which is quite high for this kind of equipment, can be considerably reduced with a silencer screwed on the exhaust connection.
