What are Vacuum Conveying Systems?

Each vacuum conveying system consists of a pick-up point, a vacuum receiver, a vacuum producer and a UL certified control panel.

A pick up point in a vacuum convey system can be a wand to convey from a drum, a bag dump station, bulk bag unloader or even a truck or a rail car.

The cost of vacuum conveying systems is dependent upon knowing the parameters of the application and the volume of material to transfer helps determine how much automation is required in a system.

Conveying from a container of material to a vacuum receiver with a wand is a low cost system where an operator moves a wand through the product in the drum. An operator can safely convey up to 5000 pounds of material per hour (or even a bit higher) with a wand. To achieve rates higher than 5000 pounds, material must be fed, by gravity, into the convey line, with one of the other methods mentioned above.

An operator dumping 50 pound bags into a bag dump station can achieve approximately 100 pounds per minute (2 bags per minute) and much higher rates can be achieved when discharging material from bulk bag unloaders. Read the article on Considerations for Pneumatic Conveying Design here.

Vacuum Conveying Systems

Below is a brief description of the components of a Vacuum Convey System.


The wand is used primarily when conveying from drums or other containers. The operator inserts the wand into the container and the material is sucked through the wand into the convey line.

Bag Dump Station

Bag Dump Station Used to convey material from smaller bags, such as 25 kg bags, the operator lifts the bag onto the bag dump station grate, cuts a slit in the bag and then turns it over where material falls by gravity into the convey line. If the material is not free-flowing or is sticky then a screw discharger may be used to meter the material into the convey line.

Bulk Bag Unloader

Bulk Bag Unloader Also known as a bulk bag discharger, bulk bag unloaders handle large super sacks (2000 pounds). Super sacks come fitted with a loading spout and a discharge spout. When a sack is placed on the frame, the operator unties the discharge spout to allow the material to flow by gravity to the conveying line.


Tubing and Hose Tubing and hoses are vital to a vacuum convey system as they transport materials from one point to the next. Tubing is always metallic and commonly stainless steel. Lengths of tubing are connected using compression-type couplings; however, in sanitary systems, tubing is polished and connected using ferrules. Flexible conveying hose is FDA and USDA accepted, smooth bore and static conductive. Never use non-static conductive hoses or PVC tubing.

Vacuum Receiver

Vacuum receivers come in all different shapes and sizes. From .25 cubic feet to 300 cubic feet in capacity, vacuum receiver sizing depends on the bulk density and rate (pounds per hour) of the system. offers vacuum receivers for all types of powders for the food, pharmaceutical and chemical industries.

Filters and Filter Housing Assemblies Like vacuum receivers, the filters in a vacuum convey system depends on the application. VAC-U-MAX uses static conductive filters and our pulse filter cleaning system keeps the filters clean and the system running efficiently.

Vacuum Producers

Vacuum producers, or air movers, are the heart of the vacuum conveying system. offers four options to create airflow in a system.

Venturi Power Units

These operate using compressed air and have no moving parts. The venturi power unit is a low-cost way to use a vacuum conveying system and is easy to install.

Positive Displacement Vacuum Pumps

Using a rotary lobe pump belt driven by a motor the PD Pump creates the vacuum. Primarily used for dilute and semi-dense convey systems.

High Vacuum Pumps

It is used for dense phase conveying where the material conveys in slugs through the tubing.

Regenerative Blowers

These are lower in vacuum and higher in airflow and are excellent for use when conveying granular or pelleted products.

Control Panels

If the Vacuum Pump is the heart of the system then the control panel is the brain. Chiyu is a UL Certified Builder of control panels and constructs them according to application. Even the simplest systems utilize a micro PLC to control convey, discharge and pulse functions and more complex PLC control panels are furnished for more involved batch weigh systems and multi-ingredient handling systems.
