In the effort to develop ever faster and more energy efficient processes for melting aluminum, electromagnetic pumps play an ever more important role. These pumps permit fast and uniform mixing of the melting bath without mechanical moving parts. The key to optimized pump operations are wear-free, low-maintenance, chemically resistant linings. 3M™ Silicon Nitride Pump Liners (previously: EKatherm® silicon nitride) provide the ideal answer to these requirements and, thanks to their low wall thicknesses, enable optimum utilization of the electromagnetic field of the pump. 3M™ Silicon Nitride is the material of choice for the cost-optimized operation of electromagnetic pumps.
