Premium Foundry Scalping Drums

Extend Component Service Life. Reduce Maintenance Costs. Improve Foundry Equipment Reliability.

Foundry equipment operates in demanding environments where abrasive media, continuous material movement, and repeated mechanical loading can accelerate wear on critical components.

SAS Global Corporation manufactures premium wear-resistant scalping drums engineered for the demanding operating conditions found in shot blast and foundry sand processing equipment. Premium replacement scalping drums for selected Wheelabrator, Pangborn, and other compatible industrial systems.

Our scalping drums are custom-manufactured using carbon steel, alloy steel, or 11–14% manganese steel, with optional wear-resistant enhancements and rebuilding services available for suitable existing drums.

Whether your operation requires a replacement scalping drum, or rebuilding of an existing component, SAS Global provides engineered solutions designed around your equipment requirements.

If your current scalping drum is worn but not beyond repair, SAS offers expert rebuild services to restore performance and extend component life. A rebuilt drum can deliver significant cost savings and help stretch maintenance budgets—without sacrificing quality or durability.

Premium SureAlloy Carbide Overlay Muller Bottoms

Foundry sand mullers continuously process abrasive molding sand, creating demanding wear conditions on internal equipment surfaces. As the muller bottom wears, changes in surface condition and geometry can affect maintenance requirements and the clearances between equipment components.

SAS Global manufactures premium replacement muller bottoms using SureAlloy® carbide overlay plate for enhanced resistance to abrasive wear.

Each muller bottom features precision-ground top and bottom surfaces designed to provide consistent thickness, dimensional accuracy, and appropriate installation geometry.

The precision-ground construction helps support the required plow clearance while simplifying installation compared with certain traditional cast replacement bottoms.

SAS SureAlloy muller bottoms are custom-manufactured to the specifications of the existing equipment.

Key Features & Benefits:

• SureAlloy® Wear Technology: Provides unmatched abrasion resistance and service life in sand mulling applications
• Precision Ground Top & Bottom Surfaces: Ensures a perfectly flat installation surface, consistent thickness, & accurate plow clearance
• Fast, Hassle-Free Installation: Outlasts OEM castings and installs in less than half the time
• Consistent Performance: Minimizes wear-related variability, keeping your mulling process reliable and efficient
• Guaranteed Fit: Machined and finished to exacting tolerances for drop-in replacement without modification

Why SAS Global Muller Bottoms?

• Reduce downtime with faster changeouts
• Cut long-term costs by replacing less often
• Maintain consistent sand quality with reliable fit and clearance
• Built with over 70 years of wear-resistant innovation
