Drum Pulleys

"HDD" Heavy Duty Drum Pulley
 

Completely redesigned using PFEA in combination with their 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. 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.

Mine Duty Pro Drum

 

PPI Mine Duty Pro drum pulleys are setting a new standard for the Mine Duty Drum class. It utilizes a profiled end disc that is machined from a solid piece of plate steel. The machining process allows the removal of all the sharp edges that cause stress risers, plus tapering the end disc increases its flexibility. The most significant increase in reliability comes with the removal of the hub to end disc weld that is no longer necessary because the hub is machined directly into the end disc. This vulnerable weld is the culprit in the vast majority of pulley failures, so by removing the weakest point in the design we can offer an unmatched level of reliability in the Mine Duty class. Available with XT bushings only.

 

Engineered Class Drum Pulley
 

Bulk handling systems are moving to larger conveyors and increased capacities. The high modulus, high tension belts require pulleys of much higher capacity and durability than standard units. PPI has the experience, know how, and equipment to custom design (using our PFEA in combination with our IP-Life model) and fabricate pulleys for each pulley location and application. PPI Engineered Class Pulleys are supplied with various hub and bushing systems.
