The ChemGrout CG-600 High Pressure series are skid mounted, colloidal grout plants. This unit is available with a 13 cubic foot high shear colloidal mixer, an agitated storage tank and a high pressure plunger grout pump. The colloidal mixer is equipped with a 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 equipped with a bridge breaker to break apart the material before entering the colloidal mixer. The agitated storage tank is available in 13 CF or 17 CF and equipped with a variable speed high-efficiency paddle mixer that maintains a thoroughly mixed grout while waiting to be pumped. The grout pump is connected directly to the agitated storage tank to provide a continuous pumping operation. The grout pump is a double acting, positive displacement plunger style that is available in three different sizes, 3X8 and 2X8, offering discharge pressures of 1,000 psi and 2,000 psi respectively. The double-acting plunger pump is designed so that conversion between the pressure outputs is easy and cost effective. Operator controls are centrally located for efficient production. The pump has patented fasteners that dramatically reduce disassembly time for cleaning and maintenance.
