Bentonite usage can mean the difference between failure and success in pipe bursting, pipe ramming and directional drilling applications.
The Grundomudd uses a Venturi mixer/filtration system to mix water and bentonite in a matter of minutes, while an in-tank recirculating valve keeps that mixture from settling. A Hypro diaphragm pump is used for pumping the bentonite mixture into the bore hole. Bentonite specification: Two 50 lb. bags of bentonite combined with 225 gallons of water will yield a 5% mixture.
Clean-up is faster with a tank isolation valve; pump lines can be cleaned without draining the tank. The unit also provides easy freshwater flushing and easy antifreeze protection.
