ChemGrout CG-500/3X8 Grout Pump

CG-500/3X8 Air Powered Shown

The ChemGrout CG-500HP series are skid mounted, high-pressure grout plants.  These units feature two 70-gallon (265 liters) mixing tanks, a 21-gallon (80 liters) holding hopper and a high-pressure plunger grout pump.  The unique double mix tank design permits continuous pumping as each mix tank alternates feeding the pump.  Each mixer is equipped with baffles, bag breakers and variable speed high-efficiency paddles that provide rapid mixing.  The tank outlets are large slide gates that allow viscous grouting materials to flow quickly into the removable holding hopper.  The holding hopper is connected directly to a double acting, positive displacement plunger pump that is available in three configurations, 3x8, 2x8 and 1x8, offering discharge pressures of 1,000 psi, 1,600 psi and 2,000 psi respectively.  The plunger pump is designed so that conversion between the pressure outputs is quick, easy and cost effective.  The pump has patented fasteners that dramatically reduce disassembly time for cleaning and maintenance.  Operator controls are centrally located for efficient production.
