+1 (978) 295-7538DP-CPW1138 4350 PSI Cold-Water Cleaning for Concrete, Fleet, and Ag Crews
The DP-CPW1138 pairs 4350 PSI with 5.0 GPM for 21,750 cleaning units, the combination of pressure and flow that strips grease, mud, and embedded grime instead of just wetting it. An 11.8 HP (420cc) gas engine with electric start drives a triplex ceramic plunger pump through a direct-drive coupling, and a gun shut-off unloader protects the pump when the trigger is released. This is a cold-water unit built for crews that clean hard surfaces daily and need output that holds up over a full workday.
DP-CPW1138 Pressure and Flow
- 4350 PSI at 5.0 GPM — 21,750 cleaning units for concrete, heavy equipment, and vehicle exteriors.
- Triplex ceramic plunger pump — direct drive with a gun shut-off unloader for sustained daily runtime.
- 11.8 HP 420cc engine — electric start, throttle control, and low-oil shutdown to protect the engine.
- 50 ft hose rated to 7250 PSI — reaches across a lot with a 48 in. wand and 0°, 15°, 25°, 40° quick-connect nozzles.
- Powder-coated steel frame — flat-free 9.5 in. wheels move the unit over gravel and broken ground.
- 3/8 in. quick-connect fittings — standard sizing for surface cleaners, extensions, and other accessories.
DP-CPW1138 Applications and Environments
The DP-CPW1138 suits contractors washing concrete pads and building exteriors, fleet operators cleaning trucks and trailers, and agricultural operations rinsing implements, barns, and livestock areas. Facility maintenance crews use the 4350 PSI output on loading docks and equipment yards where degreasing has to happen fast. Because it runs on gas with electric start, it works on sites without reliable power, and the flat-free wheels and 50 ft hose let one operator cover a large area from a single setup. The four-nozzle kit lets crews step down from a 0° concentrated jet to a 40° fan for softer surfaces, and the 3/8 in. fittings accept a surface cleaner for flat concrete work. EPA certification and a one-year parts and labor warranty back the unit for commercial daily use.
