PC Series

With a flange connection to feed from a transitube® Antibridging device or hopper, as well as from an existing container.

Field of application

The feeders of the PC Series are used as individual units for feeding machine hoppers and can also be built into complex multi-feeding units. With their modular inlet and outlet flanges they can be easily combined with each other.
By the use of a clamping ring system in conjunction with various accessories consisting of valves, angular segments, Y-pipes, etc., almost any conveyor variant can be realized.
The simplest variant is a feeder type PC combined with a hopper type SC and a mounting kit for the machine hopper. This combination includes everything the customer needs to fill the machine hopper.


Products in powder form can be conveyed dust-free by using a spiral with high rotational speed. Because we abstain from using air as a medium for transport the feeder is a closed system from which no dust can escape. At the same time the rotation of the spiral provides a continuous homogenization, a separation of the product is impossible. One of the advantages of a spiral conveyor compared with a slow turning screw is that the material is not pushed through the tube, but fluidized by the rotational speed of the spiral. Hence the feeders are not prone to wear and tear, operating lives of 25 years and longer are no rarity.


The feeders of the PC series are equipped with a clamping ring at the inlet and outlet which makes it very easy to connect them to existing loading points (e.g. silos, big-bag-stations). The diameter of the connections depend on the feeding volume, to guarantee a proper flow rate.
The feeders are available in 6 performance ranges which are distinguished by the diameter of the outer tubes.
