Flexible Screw Conveyors are available in a wide range of configurations to suit various applications, material types and site layouts. Below is a comprehensive look at the technical capabilities and options.

Tube Diameters

• North America – 2¼” to 8¾“ 

• Europe – 37 mm to 196 mm 

• Typical Throughput – Up to 58,000 lb/hr (26,308 kg/hr), depending on material and incline 

• Conveying Distance – Up to 40 ft (12 m) in a single run; longer distances possible via staging 

Configurations & Routing

Flexible screw conveyors offer versatile solutions. These innovative conveying systems can be adapted to a variety of configurations, with some common examples outlined in the image above. 

Power & Controls: 

• Motor sizes from 2–7.5 HP (1.5–5.6 kW) 

• Reversible drive options for cleaning or multi-directional conveying 

• Fully integrated control panels and PLC/HMI connectivity 

Sanitary & Maintenance Features: 

• Tool-free disassembly for quick cleaning 

• Optional Clean-in-Place (CIP) system 

• Dust-tight construction to improve hygiene and air quality 

• Suitable for washdown environments in food and pharma sectors 

Safety & Compliance: 

• ATEX-rated designs for hazardous environments 

• Enclosures and guarding for operator protection 

• CE-marked and compliant with international safety standards 

Q: What materials are suitable for Flexible Screw Conveyors?
A: They handle various dry bulk materials, including powders, flakes, pellets and granules. Typical materials include flour, sugar, salt, coffee, plastic regrind and chemical powders. They are not suitable for wet, sticky, or sludge-like materials.

Q: What makes Flexible Screw Conveyors different from rigid auger systems?
A: Unlike rigid systems, FSCs use a flexible plastic or steel tube that allows routing in multiple directions, including vertical. This makes them more adaptable in tight spaces and existing facilities.

Q: Can I use one conveyor for multiple materials?
A: Yes, if materials are compatible, cross-contamination isn’t a concern. For food or pharma applications, we recommend clean-in-place systems or dedicated conveyors.

Q: How do I clean a Flexible Screw Conveyor?
A: Most models can be disassembled quickly without tools. Optional reversible motors and CIP (Clean-in-Place) systems are available to support hygienic operations, especially in food environments.

Q: What is the maximum angle of incline for conveying?
A: FSCs can operate up to a 90° vertical incline, though throughput decreases as the angle increases. A flat or gently inclined configuration yields the highest flow rate.

Q: How does the conveyor prevent material separation during transfer?
A: The rotating screw action naturally re-blends materials, which is ideal for pre-mixed products or fragile blends.

Q: Can it be used in explosive or hazardous environments?
A: Yes. ATEX-rated designs and explosion-proof motors are available for use in dust-sensitive or hazardous areas.

Q: What are the power requirements?
A: Motors typically range from 2 to 7.5 HP (1.5–5.6 kW), depending on conveyor length, angle and material density.

Q: How long can a single unit convey material?
A: Standard runs can reach up to 40 feet (12 meters). For longer distances, multiple units or transition points can be used.

Q: Are mobile or portable units available?
A: Yes. Many models can be mounted on a mobile frame to allow for repositioning across multiple lines or batching stations.
