The ChemGrout CG-542 Series are skid-mounted grout plants specially designed for work in confined work areas. Two 22-gallon mix tanks, a 10-gallon holding hopper and progressing cavity pump provide a continuous, non-stop pumping process. Mix tanks are equipped with baffles, bag breakers and variable speed high efficiency paddles that provide rapid mixing. A unique feature of these mix tanks enables the tops to be removed for quick and easy clean up.

Once the material is mixed, it passes through the large slide gates of the tank outlet valves into the holding hopper. The 10-gallon holding hopper is equipped with an auger to keep material thoroughly mixed while waiting to advance to the pump suction housing. A positive displacement, progressing cavity, rotor-stator type pump then delivers the material to the application.

Operator controls are centrally located for efficient production.

All components are easily accessible for operating, cleaning and maintenance.
