SPX Flow’s Waukesha Cherry-Burrell (WCB) has completed a fully circular economy model in pump rotor production at its Delavan, Wisconsin facility.At the core of WCB’s circular model is Alloy-88, a proprietary metal alloy developed in-house. Alloy-88 rotors are designed to withstand intense use in food processing pumps. When these rotors wear down with time, customers can return them to SPX Flow, where they are remelted and reshaped into new rotors—keeping valuable metal in use and reducing landfill impact
WCB has recently added a sand mold recycling program which is approved by the Wisconsin Department of Natural Resources. In partnership with The Recy Group, sand used in WCB’s casting process is now recycled for road construction. This reduces WCB’s landfill impact by more than 90 tons per month.
The sand mold recycling process now completes the cycle. After Alloy-88 is poured into sand molds to shape the rotors, the molds cool and harden, then are broken away to reveal the rotor. Instead of discarding this sand, SPX Flow now collects and sends it to
