ChemGrout CG-550B/Bowie

The ChemGrout CG-550B bentonite well grouter series are skid mounted units. A large 170 liter baffled mix tank is equipped with an efficient paddle mixer that blends bentonite and polymer/bentonites quickly and completely. These units feature a Bowie gear pump that gently pumps the polymer bentonites, allowing the critical time needed to place the material within the cavity. The Bowie pump is also used to pump the water into the mix tank, an automatic check valve design simplifies operations and ensures reliable batch making. The standard self-contained models are powered by a 8 HP gasoline engine, optional 13 HP engine available. The pump and mixer are driven by dependable and powerful hydraulic motors. Models are also designed for external hydraulic power sources to meet your needs.
