Screw Conveyors Can Now Prevent Product Loss with New Shaft Seal Solution

Groove Seal Screw: A Revolutionary Solution to Prevent Product Loss

Screw conveyors play a vital role in many industries, including food processing, pharmaceuticals, and agriculture, by efficiently moving bulk materials from one place to another. However, one of the biggest challenges faced by operators of screw conveyors is product loss. Even the tiniest of gaps between the screw and the trough can cause significant material wastage during the conveying process. But, thanks to the innovative solution developed by Inpro/Seal, the AM CEMA shaft seal for screw conveyors, this problem can now be effectively resolved.
New Shaft Seal Eliminates Product Loss on Screw Conveyors |

Invented by Inpro/Seal in 2005, the AM solutions design is one of the most reliable methods for preventing product loss on screw conveyors. The AM CEMA shaft seal is specially designed to eliminate the small gaps that exist between the rotating screw and the trough. This seal creates a positive seal around the shaft, thereby confining the material within the trough, reducing product wastage and ensuring dust-free operation.

The AM CEMA shaft seal is designed using an innovative groove seal screw technology that provides a consistent seal around the screw conveyor. The groove seal screw is made of composite materials and has a unique geometry that creates a seal around the shaft, even in conditions of high temperature and pressure. Moreover, the seal conforms to the shape of the screw, ensuring enhanced sealing effectiveness.

One of the significant advantages of the AM CEMA shaft seal is its easy installation process, which can be carried out without any modification to the existing bearings or shaft. The seal is available in various standard sizes and can be customized to meet specific requirements. Also, the AM CEMA shaft seal requires minimal maintenance, saving both time and cost for the operator.

Inpro/Seal's AM CEMA shaft seal is the perfect solution for conveying abrasive and fine materials that can cause wear and tear of the rotating shaft. Additionally, the seal prevents the ingress of contaminants and external environmental factors, improving the longevity of the conveyor. As a result, this innovative solution is both practical and economical for the operator.


Inpro/Seal's AM CEMA shaft seal is a breakthrough solution for screw conveyor operators who want to prevent the wastage of bulk materials during the conveying process. The groove seal screw technology used in the seal ensures a consistent seal around the shaft and reduces the gap between the screw and the trough. This innovation eliminates the need for expensive and time-consuming maintenance of the conveyor system. The AM CEMA shaft seal is a reliable and cost-effective solution that enhances the efficiency of the conveying process.
