Trantec supply a range of replacement spiral augers (also known as flex augers) in both carbon steel and stainless steel in a variety of profiles, including:
- Round-section – available next day in Trantec’s four sizes at almost any length needed.
- Flat-section – sales-to-order, delivery dates may vary depending on availability.
- Square-section – sales-to-order, delivery dates may vary depending on availability.
Flexible Screw Conveyors (also known as Flexible Auger Conveyors, Spiral Screw Conveyors, and Flexible Spiral Conveyors) are employed to transport powders, flakes, and granular dry bulk solids using a rotating spiral in a plastic tube. The throughput is mainly determined by the speed of rotation and the size of the spring. Larger spirals produce higher throughputs and similarly, faster RPMs produce higher throughputs. The spiral auger profile also has a bearing on how the product is transported. Most materials will convey using a simple round-section profile but there are a few products better suited to flat or square section springs.
Nowadays, many different manufacturers produce Flexible Screw Conveyors, often using their own brand names when naming their equipment. These machines all operate using the same principles and there is nothing special about the spiral augers that they use, although some OEMs make every effort to make things appear otherwise!
Trantec can supply replacement flexi spirals for these screw conveyors. Trantec spiral augers are manufactured to the exact same standards as the original spring and are like-for-like replacement… guaranteed! The only difference is our significantly lower price.
Cost Saving Solutions
Over the last 20+ years, Trantec has worked hard to dispel the myth that only the OEM (Original Equipment Manufacturer) can supply spares for their equipment.
We can supply replacement spiral and tubes for all Flexible Spiral Conveyors, with many sizes ex-stock and ready for immediate despatch.
Trantec can now list a host of firms who have made the switch to Trantec spares, with many household brands amongst them. Many of our customers have saved thousands of pounds per year by working with Trantec, with our exceptional customer service experience included.

Flexible Screw Conveyors
Trantec specialises in screw conveyors constructed in both stainless and carbon steels, with various spiral profiles.
Flexible Screw Conveyors, or Flexi Screws as they are commonly known, transport materials in the exact same manner as other types of screw feeders.
Common products handled include powders, flakes, grains, and pills, although the list could go on. Flexi Screws can be used with multiple discharge points, providing fast and effective filling or delivery of materials.
Their special screw conveyor design and method of transport eliminate the use of an agitator for most powders and dry bulk solids providing a simple and effective process. Certain non-free-flowing or semi-free-flowing products may still use agitation to prevent bridging or rat-holing, such as very fine powders such as flour, cement, clay, and protein powder.
Flexible Screw Conveyors employ a rotating spiral auger inside a hollow plastic tube (typically UHM, PEEK, or UHMWPE) to propel materials from storage to the point of delivery.
Larger and/or faster RPMs provide higher feed rates, with alternative spiral profiles, such as square or triangular, to add greater bearing on substances and materials.
Known for their simplicity in design, Flexible Screw Conveyors allow for gentle handling of dry bulk materials without the risk of product degradation, or boring through powders instead of transporting them.
Flexi UHMWPE tubing is completely sealed and waterproof, helping to eliminate the chance of cross-contamination through airborne material particles.
Flexible Screw Conveyor/Spiral Augers – Key Features
- Gentle handling of materials.
- Low maintenance.
- Total product containment.
- Constant remixing/conditioning of powders.
- One moving part (except for non-free-flowing materials that require agitation).
- Carbon or stainless steel.
- Stationary or mobile designs of our Flexible Screw Conveyors are available).
- Approved construction available for ATEX, pharmaceutical, and food grade materials.
Trantec’s UHMW/UHMWPE tubes are excellent food grade materials, which are commonly used with most brands of Flexible Screw Conveyors.
Its exceptionally high abrasion and impact resistance qualities are renowned, making it the choice thermoplastic polyethylene for many materials handling equipment manufacturers worldwide. UHMWPE can often wear out other materials, including metals, nylon, urethanes, and fluoroplastics, whilst possessing its own extremely high standards of corrosion resistance.
UHMWPE tubing is the go-to pick for many food processing and bulk handling businesses due to its outstanding features and EC, FDA, USDA, and 3-A Dairy approval. Low maintenance costs mean low maintenance bills, extending product life and confirming money worth spent.
UHMWPE Tube – Key Features:
- Excellent low-friction properties.
- Super smooth finish inside and out.
- High impact strength.
- Excellent chemical and corrosion resistance.
- Sound absorption/dampening.
- High stress rates and energy absorption levels/capacity.
- Temperature resistant from -200 degrees to +80 degrees.
- Physiologically safe/non-toxic.
- EC and FDA approved material of extrusion.
- Self-lubricating/excellent free-flow and sliding properties.
- High wear resistance.
