UPFLOW designed and supplied a customized PVC Powder Feeding and Vacuum Conveying System for a new materials manufacturer that required a more automated and enclosed solution for transferring powder from the bag unloading area to multiple downstream receiving points, with the complete project covering powder unloading, vacuum conveying, stainless steel conveying pipelines, receiving-hopper modification, dust collection connections and centralized electrical control rather than simply supplying several independent vacuum conveyors.
According to the actual project configuration, the system incorporated five UPFLOW-320 conveying units, a conveying power source, bag unloading equipment, air replenishment devices, approximately 30 meters of stainless steel conveying pipeline, modifications to existing receiving hoppers, high-level detection, dust extraction connections, flexible connectors and an integrated control system, allowing the different pieces of equipment to operate as one coordinated powder feeding and conveying process.
The customer needed to improve the existing PVC powder feeding process because repeated manual transfer between bag opening, material handling and downstream production equipment increased operator workload and made it more difficult to maintain continuous and organized material supply, while the fine powder characteristics also made enclosed transportation and dust control important considerations during system design.
Another important requirement was that the new PVC Powder Pneumatic Conveying System had to connect with several existing receiving points rather than serving a simple one-to-one transfer process, which meant that UPFLOW needed to consider the relationship between the vacuum source, pipeline resistance, conveying distance, multiple conveying units and the existing equipment interfaces when developing the overall solution.
Instead of requiring the customer to replace the existing downstream equipment, the project also involved modifications to the original receiving hoppers so that the pneumatic conveying equipment could be integrated into the production process, making the system a customized retrofit solution based on the actual factory arrangement rather than a standard standalone machine installation.
UPFLOW developed an integrated PVC Powder Feeding and Vacuum Conveying System in which the powder enters the process through the bag unloading section and is subsequently transferred through enclosed pipelines by the vacuum conveying equipment to the designated receiving points, while level detection and the electrical control system coordinate material demand and conveying operation according to the production process.
The project used five UPFLOW-320 conveying units with SUS304 material-contact components, while the conveying network incorporated approximately 30 meters of stainless steel pipeline together with bends, pneumatic valves and flexible connections, and the conveying power section included a Roots blower according to the project configuration.
By designing the conveying units, vacuum source and pipeline network as parts of the same system, UPFLOW was able to adapt the material transfer route to the customer’s actual equipment layout while providing several downstream production points with an automated PVC powder supply.
At the beginning of the material handling process, the bag unloading equipment provides a controlled area for operators to introduce bagged powder into the system, while an integrated dust collection arrangement helps control airborne powder generated during bag opening and discharge, after which the material enters the enclosed conveying process rather than requiring repeated open transfer between different production areas.
The supplied bag unloading equipment incorporated SUS304 material-contact construction together with filtration and pneumatic components, allowing it to operate as the upstream feeding section of the complete PVC Powder Conveying System rather than as an independent unloading station.

This combination of controlled bag unloading and vacuum transportation was particularly suitable for the customer’s application because the negative-pressure conveying principle allows powder to move through enclosed pipelines while helping reduce powder escape from pipeline connections during the conveying process.
Because the customer’s production line already contained receiving equipment, UPFLOW incorporated hopper modifications into the project so that the new conveying system could connect with the existing production process, with the project documentation showing modifications involving level detection, pneumatic components, rotary feeding arrangements and additional interfaces required for material receiving.
The system was also equipped with an electrical control cabinet and PLC programming so that powder conveying, material receiving and related pneumatic components could operate according to the required control sequence, reducing the need for operators to manually coordinate each individual conveying step and creating a more integrated Automatic PVC Powder Feeding System.
After installation and system integration, the customer obtained a complete powder handling process connecting bag unloading, vacuum transportation, multiple receiving points and automatic control, allowing PVC powder to be transferred through enclosed pipelines while reducing repeated manual material movement between different stages of production.
More importantly, this project demonstrates UPFLOW’s capability to develop a complete PVC Powder Pneumatic Conveying System around an existing production line, because the scope involved not only vacuum conveying equipment but also bag unloading, stainless steel pipeline engineering, receiving-hopper modification, dust collection connections and automatic control, all of which needed to work together according to the customer’s actual plant configuration.
For manufacturers handling PVC powder and other fine industrial materials, UPFLOW can develop customized powder feeding and conveying solutions according to material characteristics, conveying capacity, conveying distance, number of receiving points, existing equipment interfaces and automation requirements.
For more project cases:
Vacuum conveying allows PVC powder to be transported through enclosed pipelines under negative-pressure conditions, which can help control powder leakage while providing flexible pipeline routing between the material feeding area and downstream production equipment.
Yes, but the final configuration needs to be engineered according to conveying distance, production sequence, required capacity and plant layout, with conveying units, pipelines, valves and receiving equipment coordinated as part of the complete system.
Yes, this project included modifications to existing receiving hoppers and additional interfaces so that the new powder conveying equipment could be integrated into the customer’s existing production process rather than requiring replacement of the complete production line.
