What the Dramm Hydra BigFoot Wheels Package Changes
The machine under the options is where to start. The Hydra 50 is a cart mounted hydraulic sprayer built around a stainless inner sleeved triplex piston pump. Dramm couple that pump to a sealed 1.5 HP electric TEFC motor turning at 1750 rpm, with no belt or chain between them. Maximum pressure is 500 PSI through a fully adjustable regulator. Maximum pump output is 4 gpm, while the standard gun delivers 1.3 gpm at the nozzle. Electrical options are 115V at 13.6A, or 208 to 230V at a lower draw. The tank holds fifty gallons, and the cart measures 50 in long, 27 in wide and 50 in tall. Two design details matter in daily use. An agitation system keeps stubborn powders in suspension rather than letting them settle or clump. A convex reel stops the hose birdnesting as it winds, which is the usual reason a reel jams. The BigFoot option is the one named here. Dramm describe it as an upgrade to pneumatic tires and casters. That is what lets a loaded cart roll over gravel, matting and door thresholds instead of fighting them.
Choosing a Hose Length on a 50 Gallon Hydraulic Sprayer
Three hose lengths are made, and the choice is about reach rather than power. Dramm supply 150 ft as standard, with 200 ft and 250 ft available instead. Longer hose gives coverage from one parking spot, which matters in a long greenhouse or a row of rooms. It costs two things in return. Pressure drops a little over distance, and a fuller reel is heavier to wind and slower to pull out. The CRF letters in the part number are the second option worth understanding. CRF stands for Corrosion Resistant Fitting, and Dramm offer it on the fifty gallon unit specifically. The wetted fittings are swapped for corrosion resistant parts, which keeps aggressive chemistry from eating the plumbing. Anyone running acids, sanitisers or salty feed through a sprayer will understand why that option exists. Gun choice is open as well. The standard gun covers a range of patterns, with the Dramm L-5 Lance and the MS-Trigger Gun as alternatives. One honest note on scale. Fifty gallons is the smallest unit in the Hydra line, and the SprayTrax and Hydra 200 models run to one and two hundred gallons.
