The ChemGrout CG-500/031 High-Capacity Geothermal Series has been designed specifically for grouting geothermal loops. These skid mounted grout plants efficiently mix and pump the high ratio sand/bentonite materials specified by loop designers. The CG-500/031 feature two 70-gallon (265 liters) mixing tanks, a large 45-gallon (170 liter) holding hopper and rugged single-acting 3" piston grout pump. Each mixing tank is equipped with baffles, bag breaker and a variable speed high-efficiency paddle mixer that provides rapid grout mixing. Tank outlets are large slide gates that allow viscous grouting materials to flow quickly into the removable holding hopper. The dual mix tanks alternately feed this large holding hopper providing continuous pumping rates up to 16 gpm. The grout pump is a 3" positive displacement, single acting piston pump that disassembles with only a hammer for fast and thorough cleaning. The rugged steel frame stands up to the toughest conditions on the job site. Operator controls are centrally located for efficient production.
