Drilling Fluid System
March 23, 2001

The FM13 Drilling Fluid System has been added to the line of Ditch Witch drilling fluid management products. The FM13 is the largest of three stand-alone, modular fluid systems designed to mix drilling fluid additives with water and deliver the slurry to directional drilling units for drilling, backreaming and product pullback. Powered by a 13-hp (9.7kW) gasoline engine, the efficient constant grease seal pump delivers 20 percent more fluid capacity than the MM9 fluid system, moving 42-viscosity slurry at the rate of 200 gpm (757 L/min.). Maximum flow rate is 300 gpm (1135.6 L/min.) of 26-viscosity fluid. The unit is available in 500- or 1,000-gallon tank and is equipped with two hoppers - one for dry fluid additives, the other for liquid mixtures and enhancers. Ditch Witch.
