Spiral Drum & Wing Pulleys


The Spiral Drum Pulley and Spiral Wing Pulley are designed to ensure constant contact with the belt to eliminate noise and vibration. Rotation of the pulley automatically starts the self-cleaning action to reduce the material build-up between the belt and pulley face and discharge of material to the sides of the conveyor.

Luff’s Spiral Wrap design ensures constant contact with the belt which eliminates noise and vibration, while still offering a self-cleaning action. Helically wrapped from the center, it discharges material to the sides of the pulleys. Spiral Wring Pulleys are for heavier duty applications and can operate over 450 fpm.
