The ChemGrout model CG502/031 is a skid mounted grout plant. This unit is designed for maximum efficiency by allowing simultaneous operation of the mixing and pumping. The ChemGrout model CG-502 features two 170 litre mixing tanks, a 30 gallon holding hopper, and the popular single-acting 3″ piston grout pump. The unique double mix tank design permits continuous pumping as each mix tank alternates feeding the pump. Each mixing tank is equipped with baffles, bag breakers and a variable speed high-efficiency paddle mixer that provides rapid grout mixing. The tank outlet is a large slide gate that allows viscous grouting materials to flow quickly into the removable holding hopper. The large holding hopper is sized to provide continuous pumping. The grout pump is a 3″ positive displacement, pulsating 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. All components are easily accessible for operating, cleaning and maintenance.
