THE ERADICATOR®
The Eradicator wing pulley’s patented design retains the belt cleaning benefits of a traditional wing while providing continuous belt contact and improved cleanout efficiency. The Eradicator’s unique design provides a cleanout rate up to 40 times faster than traditional wing design. These additional benefits provide longer component life and decreased noise. Traditional wing pulleys feature straight wings which contact the belt intermittently, entrapping and recirculating material rather than displacing it, which can lead to belt damage and pulley failure.

Enhanced Cleanout
The faster a properly sized wing pulley cleans out loose materials, the longer it will last. It’s that simple. Along with the pulley, recirculating materials can also influence the life of the conveyor belt, idlers and bearings. Self-cleaning pulleys with proven cleanout designs work to lengthen the life of your system components by quickly ejecting materials that damage and wear exposed surfaces.
Increased Life
The hybrid design of The Eradicator maximizes both the life of the pulley and the conveyor belt. PCI’s self-reinforced design discourages wing fold over and prevents incidental damage to the pulley. The Eradicator also maximizes belt life by reducing deformation commonly associated with high center point designs.
Decreased Noise
The Eradicator decreases noise by continuously contacting the belt while its straight center maximizes cleanout. Only The Eradicator achieves the optimum balance of noise reduction and cleanout efficiency.
THE ERADICATOR D²® (Directional Discharge)
Eradicator D² with Rim
The Eradicator D² (Directional Discharge) with Diamond Rim incorporates the innovative features of the Eradicator into a design allowing for operation in reversing conveyors of material sizes 3” and smaller.

Directional Discharge
The Eradicator D2 utilizes the angled wing and cleanout port design of the Eradicator to maximize material removal but unlike the Eradicator, the D2 is designed to operate in reversing/dual-direction applications. Additionally, the Eradicator D2 forces the material in a single direction so that the ejection of material will take place on one side of the conveyor. The Eradicator D2 is the first pulley of its kind to offer these innovative features.
THE ERADICATOR E²® (Enhanced Elevator)
Eradicator E² Boot Pulley
The Eradicator E² (Enhanced Elevator) Boot Pulley incorporates the innovative features of the Eradicator on bucket elevators. The optimized rim design provides constant contact with the belt, which reduces belt jumping and unintended bucket shaking. Eradicator E² angled wings facilitate proper belt cleaning, enables particulate (such as grain) to fall through rather than crush the valuable material, while controlling the flow of material discharge to one direction only.

Operation in Both Directions – Reversibility
Single Direction Discharge
Maximum Belt Contact without Bulk Material Damage or Loss
Patent# 10,442,631
THE ERADICATOR®-MAX
The Eradicator-MAX
The Eradicator-MAX wing pulley combines the unmatched cleanout rates of the Eradicator with several unique performance enhancing characteristics to create the maximum wear – life and strength solution for all diameter applications.
ALL OF THE BENEFITS OF THE ERADICATOR, PLUS…
Small and Large Diameter Performance
Maximized Pulley Use
Patent# 8,857,606
Maximized Pulley Use
The Eradicator-MAX will outlast all traditional wing tips designs. All wing tips will eventually wear to the point where they increase the risk of damage to belts and belt splices. As wing tips wear past the halfway point of the original wing tip material thickness, the pulley is operating on borrowed time. The thinning material develops sharp or thinning edges which is a leading cause of belt and belt splice damage. The Eradicator-MAX solid wing design allows for the wing to be worn without creating sharp edges.
As long as take-up travel can accommodate the change in pulley diameter, the Eradicator-MAX can be worn down to the core.
The Ice Eradicator®
PCI’s patented Ice Eradicator® is the world’s first proven solution to temper the costly effects of frozen conveyor belts. When installed in the head position, a drum style Ice Eradicator will de-ice and soften the conveyor belt encouraging startup in freezing conditions. PCI’s innovative technology can also be adapted to any Eradicator or Deflector® wing pulley to discourage problems related to ice buildup in non-drive positions.

Frequently Asked Questions (FAQs)
Does a pulley’s load capacity increase by increasing pulley material thicknesses?
While component thicknesses do contribute to overall pulley capacity, shaft diameter plays the primary role in achieving a desired load capacity. In other words, selecting a pulley with thicker components (Mine Duty over Heavy Duty, MC Series over FC Series) won’t necessarily achieve a greater load capacity if the axle is not sized to accommodate the application loads.
What is the longest length of conveyor pulley that PCI can offer?
PCI can manufacture pulleys with face lengths greater than 14 feet. Pulleys of this length require special consideration to account for shaft deflection. Small diameter pulleys of increased face length commonly utilize fixed stub shafts in place of traditional through shaft designs. Fixed stub shafts decrease the likelihood of end disk fatigue, as a result of shaft deflection. (For additional information, please see PCI Pulley Selection Guide)
When is a hub keyway needed in a conveyor pulley?
The purpose of a hub keyway is to help the transmission of torque from a shaft to the pulley in a drive application. Hub keyways are utilized on pulleys that are driving a belt. Most often, the pulley and belt are being turned by the shaft which is being powered by a motor, gearbox, or sprocket. The hub keyways provide the bushing another point of contact to help drive the torque from the motor or gearbox.
When is a hub keyway NOT needed in a conveyor pulley?
The pulley that is in a non-drive position, is driven by the belt and not the shaft. When utilizing compression hubs and bushings there is sufficient grip on the shaft from the bushings themselves. A hub keyway is not needed for pulleys that operate in driven (non-drive) positions.
Wing: What applications benefit from using a Wing Style conveyor pulley?
Also known as self-cleaning pulleys, wing pulleys are primarily used on the tail end of bulk handling systems where loose materials tend to reside on the underside of the conveyor belt, causing damage to one or both components. Wing pulleys incorporate a non-continuous contact surface comprised of individual wings or fins. This construction results in the creation of open voids that allow loose material to fall away from the contact surface. In applications where continuous contact is desired, a spiral style or Eradicator® Wing pulley can be utilized.
Wing: How do I specify additional reinforcing agents such as gussets and reinforcing rings?
While we welcome your custom designs, PCI has designed our Wing Pulleys with standard options for construction choices like gussets and reinforcing rings. PCI Heavy Duty Wing pulleys feature the use of gussets while PCI Mine Duty Wing pulleys feature gussets and reinforcing rings as a standard design detail.
