Product Overview


The ChemGrout CG-680 High Pressure series is a high pressure, high capacity, skid mounted colloidal grout plant. The HP colloidal series easily mixes and pumps slurries of cement, fly ash, bentonite and lime flour. Each grouting machine in this series is designed to provide a continuous mixing and pumping operation. These units feature a 17 cubic foot homogenizing colloidal mixer, a 17 cubic foot agitated storage tank and a 32 GPM grout pump. The colloidal mixer is equipped with a 2X3X12 high shear centrifugal diffuser-type pump that disperses the cementitous material down to its finest particle size to achieve complete particle wetness. The mixing tank is also equipped with a bridge breaker to break apart the material before entering the colloidal mixer. The agitated storage tank is equipped with a variable speed high-efficiency paddle mixer that maintains a thoroughly mixed grout while waiting to be pumped.
