Features:

• Continuously meters and mixes liquid and dry materials together, normally within +/- 1% density range.
• Mechanically variable speed drives or AC frequency drive inverters are utilized for control of liquid and dry material delivery, slurry mixing and pumping.
• Ideal for Portland cement slurries at either low or high viscosity. Low viscosity grout can be pumped at 35 gallons per minute at a pressure of up to 200 psi. High viscosity grout can be pumped at 15 gallons per minute at a pressure of up to 400 psi.
• 200 lbs. (90 kg) fine powder hopper capacity. An auxiliary material feeder is recommended for uninterrupted slurry production.
• An auxiliary foam generator can be added for cellular concrete production.
• Essentially self-cleaning by automatically flushing system with water after slurry production.
