The Geo-Loop 40-500 provides a continuous flow of grout, offering the ability to pump a continuously metered flow of polymer-coated bentonite grouts at rates of 0 gallons to 40 gallons per minute at pressures up to 500 psi. The 60-gallon stainless steel mixing tank features a stainless steel paddle mixer and a smooth, tapered cone bottom. The core of the system is the 5-inch bore, 8-inch stroke, chrome-lined cylinder in the piston pump. Operated by a 20 HP Honda two-cylinder, electric-start engine, this grouter also includes a 10-gallon hydraulic oil reservoir and thermostatically controlled oil cooler with a 12-volt fan.
