The ChemGrout model CG-550P is a skid mounted, air powered grout machine. This system is designed to provide a continuous operation of mixing and pumping. This unit features a 34 gallon (129 liter) mixing tank and the field proven CG-050 grout pump. The mixer is equipped with baffles, bag breakers and variable speed high-efficiency paddles that provide a rapid mixing cycle. The tank outlet valves are large slide gates that allow the thickest materials to fall easily into the pump hopper. The holding hopper is connected directly to the suction of the grout pump to provide a continuous pumping operation.
