The Series 1000 Center Drive Reclaimers are the work horse of the Weaver Reclaimers product line. Available in single screw and twin screw designs; they can operate successfully in flat bottom storage tanks and silos up to 50 feet (15.2 meters) in diameter. The industrial-grade motors drive the auger from the center while the augers slowly sweep around the silo. The auger draws the material into the center unit where it transfers the material down through a hopper to the out feed conveyor. Designed to meet Zero Entry requirements for maintenance the reclaimer’s center drive units are located below grade for ease of maintenance and service without emptying the silo.

CST’s dedicated engineering team creates each reclaimer from Richard Weaver’s field-tested designs to meet the reclaim performance rates required for each specific application. Complete electrical packages are available including optional variable frequency drives (VFD), or reclaimers can be provided with motors-only for integration by others.
Series 500 Weaver Center Drive Reclaimers are designed and manufactured with the following benefits;
- All Electric Drive - Better integration, performance and maintenance. No leaks as with hydraulics.
- Standard Industrial Components – Reduced upfront, maintenance and service costs. Reduced parts inventory.
- Zero Entry – Serviceable from outside the silo. Heightened safe operation and reduced maintenance costs.
- No Free Flow Designs – Controlled, predictable flow with no flooding or rat-holing

Since 1962 Weaver Reclaimer Systems have been successfully installed to convey even the toughest materials from the hopper bottoms of storage silos. In 2011 Weaver Reclaimers began being designed and manufactured by CST Storage, the global leader in storage solutions including BulkTec™ and Columbian TecTank™ silos. Now Weaver reclaimers are manufactured at CST’s 500,000 ft2 ISO-Certified manufacturing facility in DeKalb, IL that also manufactures Goliath, Hercules, ForceFlow, Alliance and XL unloaders going back to 1948. All Weaver Reclaimers are now backed by CST’s warranty and dedicated field service teams around the globe.
Who understands reclaimer design and material flow better than one of the only companies that manufactures reclaimers, silos and unloaders? - CST. Weaver Center Drive Reclaimers are available as standalone units for integration by others or integrated with new or existing CST BulkTec™ silos, concrete storage silos and welded storage silos.
