The Geo-Loop 50-500 grout system from Geo-Loop Inc. features a grout pump constructed of a 5-inch bore, 8-inch piston pump with chrome-lined cylinders and hammer union construction. Driven by a 20-HP Honda engine, the grout pump has a variable flow of 0-50 gallons per minute at 500 psi. A 190-gallon-per-minute tank fill pump and hydraulically driven mixing paddles enable high production grouting. High volume 130-psi pressure on the rinse line cleans the tank quickly. Heavily built and powder-coat painted for strength and durability, the Geo-Loop 50-500 works with bentonite, bentonite sand, thermal-enhanced and cement grouts. Geo-Loop Inc.
