PPI introduces the all new ProDuty® pulley. The pulley that no matter how big or how small the project, it’s the only one you need. We’re so confident in how well it can get the job done, we back it with the only 10 year warranty in the industry.
Completely redesigned using PFEA in combination with our IP life program. Steel rims, hubs, and discs are fused into an integral component by a continuous submerged arc welded bond that maximizes pulley strength, balance, and concentricity. Available with various hub and bushing systems.
The PPI Spiral Drum Pulley is formed by a pair of vertical steel bars helically wound around a PPI "HDD" Heavy Duty Drum Pulley. This unique design reduces buildup between the belt and the pulley while providing continuous belt contact for applications where wing pulleys cannot be used. Rotation of the pulley automatically starts the cleaning action, discharging foreign material to the side of the conveyor. Available in crown or straight face and also with various hub and bushing systems.
This unique pulley and shaft arrangement allows for fast, safe, and economical bearing and shaft replacement without removing the pulley from the conveyor. It reduces maintenance time, downtime, and scrap loss by using rugged engineered stub shafts. The pulley and shaft system is manufactured to CEMA standards and Mine Duty specifications.
