Screw Conveyors

Flexible Screw Conveyors

With Trantec dispelling the myth of OEM’s being the only provided of flexi screw coils and tubes we can offer Flexible Screw Conveyors without the premium price coupled with next day delivery on replacement tubes and coil.

Trantec Flexible Screw Conveyor

Trantec also specialise in Screw Conveyors  both in stainless and carbon steel in various profiles. Flexible Screw Conveyors or Flexi-Screws as they are commonly known transport the same manner of materials as other Screw Feeders e.g. flakes, powders etc they can be used with multiple discharge points to provide fast and effecting filling or delivery of a product. With their special Screw Conveyor design and method of transport this eliminates the use of an agitators (with some products) providing a simple and effective process. This then provides great value for money with such a low cost machine. Flexi-Screws use a rotating spiral inside a plastic tube (usually UHM, PEEK or UHMWPE) to propel materials. Larger and or faster rotation provide greater feed rates. For trickier materials simple rounded spiral may not be appropriate, Trantec provide square, triangular section Spiral which profile will provide greater bearing on substances/materials.

Because of the method in which Screw Conveyors design and simplicity it allows for gentle method of transport without the risk of damage to the product, or boring through products instead of transporting. With the Flexi-UHMW Tube being a sealed unit this helps eliminate the chance of contamination through products mixing or by Air as the tube is sealed and waterproof.


UHMW Tubing

Trantec provide UHMW/UHMWPE tubing (Ultra High Molecular Weigh Polyethylene) these tubes are excellent food grade materials, these are commonly used in a Screw Conveyor. This is due to its exceptionally high abrasion and impact resistance properties. It often out wears other materials such as some metals, nylon, urethanes and fluroplastics, it also has an extremely good standard of corrosion resistance. This is what makes UHMWPE tubing the go to pick for food handling and bulk handling companies because of its outstanding qualities coupled with FDA, USDA and 3-A dairy approval with low maintenance costs. This means low maintenance bills with long product life making it money worth spent.
