DP-300

The 300 Series was created as an answer for the NEW contractor to test the water without a substantial initial investment. The price tag suggests an "economy" class but these little giants have it all!

To achieve a low cost machine, we set out to build a small unit with an air pump and hand agitation. After selecting the best dual-diaphragm pump and air compressor, we put everything else we could fit. The result was the perfect machine for a beginner to start with, and the perfect complement to any large fleet of professional sealcoaters.

The deck shown (Figure 1) is 1⁄4-inch steel plate. Also shown is fencing with ramp available as an option. Other options include a brush box, a hose reel, 15-foot suction hose, and a 25⁄16-inch ball hitch in place of the military-style pintle.

• We managed to fit the same manway and surge tank on these that you'll find on our larger units. The tank may be smaller, but the guy who climbs inside to clean it sure isn't.
• As on larger units, the 75-foot × 3⁄4-inch hose with 6-foot aluminum hand wand is used for application.
• 3-to-1 gear reduction on the hand crank makes easy work of turning the 4-paddle agitator.
• The 8-gallon Jenny compressor powers the Versa-Matic, clamped metallic, dual-diaphragm pump to provide a steady strong spray that results in professional jobs and repeat business.
• The 4-foot extended trailer provides space to haul everything to the job site in one trip!
• The skid model (Figure 2) has a perfect deck space for a blower or crack sealer.
• The skid unit can be mounted to truck or trailer. Haul it to and from the site on your typical pickup truck. The frame is designed to fit between wheel wells! ^[1]

Need extra capacity on wheels; more power?

Check out the ESP/ESSP-550 Series or ESP/ESSP-760 Series (also available as skid).

• Most 1-ton vehicles are only rated to handle this tank when empty. Check your vehicle's GVRW before transporting this tank on the highway with any sealer inside.
