Description
Blast layers of industrial grease, marine growth, and oxidation off hard surfaces. The Simpson Aluminum Water Blaster 4400 PSI unit provides harsh commercial cleaning pressure. A belt-drive system isolates the pump from engine vibration. The large chassis footprint demands dedicated space inside enclosed work trailers.
Aircraft-grade 6061 aluminum plate forms the one-piece corrosion-resistant cart frame. A 389cc Honda GX390 gas engine drives an industrial CAT triplex plunger pump via dual cogged belts. Ceramic plungers resist thermal shock and abrasive friction inside the brass manifold. Dual pneumatic tires absorb severe vibrations across rocky construction surfaces. Vented steel guards cover the drive pulleys.
Belt Drive System Parameters
Fleet operators strip vehicle frames fast using high water volume and extreme pressure. The low-speed pump mechanism doubles operational hours between packing replacements.
- Commercial 389cc Honda engine delivers continuous torque output on remote sites
- Belt-drive CAT triplex pump generates 4400 PSI at 4.0 GPM fluid delivery
- Aircraft-grade aluminum frame eliminates frame rust from road salt exposure
- Dual drive belts reduce pump rotation to 1750 RPM for extended seal life
- Integrated unloader valve safeguards pump chambers from dangerous pressure spikes
- Five quick-connect nozzles change fluid stream patterns for diverse wash projects
- Monster 50-foot steel-braided hose resists kinking and abrasion from concrete
Dynamometer Stress Bench Data
Dynamometer bench testing demonstrates 3460 RPM engine speed under maximum 4400 PSI operational resistance. The CAT pump rotates at 1720 RPM while delivering 3.96 GPM flow. Pump oil temperature stabilizes at 114°F after 4 continuous testing hours. Engine fuel burn measures 0.94 GPH at full operational throttle. Acoustic meters register 90 dBA at 7 meters.
Worksite Performance Practical Notes
You push this balanced cart across turf surfaces without tearing green grass. The belt-drive configuration cuts hand vibrations during 8-hour continuous cleaning runs. Do not hook this machine to domestic well spigots with low flow. Water shortages induce cavitation bubbles that destroy CAT ceramic plungers.
- Inspect drive belt tension deflection distance every 100 run hours
- Drain pump crankcase fluid after the initial 50-hour operational cycle
- Lubricate wand quick-connect couplers to prevent internal brass locking seizure
Commercial Warranty Specifications
Simpson covers the Honda engine for 3-Years, the CAT pump for 5-Years, and the frame for 10-Years. The wooden shipping pallet holds the pressure washer, 50-foot hose, spray gun, 48-inch lance, 5 quick-connect spray tips, and operator manuals.
