Metpump Product Technology

Product Technology

All Metpump® brand products are colloidal silica bonded refractory. Their fine colloidal silica particle size promotes extraordinary properties such as superior hot strength and mechanical strength. Metpump products also resist thermal shock, creep, erosion, abrasion and chemical attack.

Installation Technology

Magneco/Metrel’s Metpump system is delivered in two components: Metpump dry powder and Metset liquid binder. The product can be mixed and installed onsite, or precast shapes can be shipped. Once combined, the product can be poured, pumped or shotcreted in the place of application. Our products are formulated for pumpability without dilution. Material is applied at  a rate of five tons per hour for shotcreting and ten tons an hour for pumping without sacrificing the quality of the final product.


Metpump sol-gel bonded refractory products offer the fastest possible dry-out. The products are unique as they do not contain any chemically bonded water. No chemically bonded water means that all free water is removed from the refractory once the temperature reaches 100 °C (212 °F).
