CG-500 High Pressure Series


CG500/3X8/A	CGPU15/EH3	CGPU20/GHES	CGPU24/DHES	CG500/3X8/H

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 positive displacement, double acting 3X8 plunger pump that delivers 20 GPM, 1,000 PSI. The pump is also available with 2X8 plunger kits that offer a higher discharge pressure of 2,000 psi with a slightly lower flow rate of 16 GPM. The plunger pump is designed for simple conversion between the pressure outputs by purchasing plunger group conversion kits. The pump has patented fasteners that dramatically reduce disassembly time for cleaning and maintenance. Operator controls are centrally located for efficient production.

Applications include:

Civil Engineering - soil nails, tiebacks, earth anchors, high pressure rock grouting
