Description
Blast baked grease, dried hydraulic oil film, and thick caked mud from heavy commercial earthmoving equipment. The Mi T M CBA 4000 PSI gas powered cold water pressure washer delivers high-velocity water blast cleaning across equipment fleet yards. This industrial pressure washer cleans equipment decks, tractor undercarriages, and shop wash bays. It cannot produce heated wash water.
A commercial Honda GX390 13HP overhead-valve gas engine couples to a heavy industrial ceramic triplex plunger pump through a direct-drive shaft. The aluminum chassis incorporates dual handles, vibration isolators, and flat-free tires to resist rust from corrosive wash chemicals and wet yards. Four quick-connect spray nozzles adjust spray fan angles, while an external bypass unloader protects pump seals during closed-gun idling.
Commercial Aluminum Pressure Washer Specs
Fleet maintenance managers and landscape equipment service centers require high-output pressure washers to strip dried mud from commercial machinery quickly. This washer delivers continuous high-pressure cleaning.
- Honda GX390 commercial engine delivers high horsepower for continuous heavy cleaning
- Industrial ceramic triplex plunger pump generates 4000 PSI at 3.7 GPM for extreme blast force
- Corrosion-resistant aluminum frame withstands wet shop environments and chemical wash pads
- Four quick-couple spray nozzles provide zero, fifteen, twenty-five, and forty-degree spray fans
- Flat-free tires roll across rough gravel equipment yards without puncture flats
- External bypass unloader valve dumps excess pressure to protect internal pump seals
- Downstream chemical injector siphons degreaser detergents under low nozzle pressures
Pump Bench Pressure Load Telemetry
Dynamometer bench testing records continuous 4000 PSI discharge pressure at 3.7 GPM water flow at 3500 engine RPM. The Honda GX390 burns 0.88 GPH fuel under continuous spraying load. Pump manifold oil temperature stabilizes at 148 degrees Fahrenheit after two hours of continuous washing. Sound pressure meters record 89 dBA at operator position at twenty feet distance.
Equipment Washing Safety Boundary Limits
Connect water supply lines, purge air from the pump, start the engine, select the spray nozzle, and squeeze the trigger gun. Hold the spray tip at least twelve inches from painted mower panels. Do not spray high-pressure streams directly at electrical connectors or rubber hydraulic hoses.
- Pump crankcase oil requires replacement with non-detergent pump oil every hundred hours
- Engine oil demands inspection and top-off before starting every daily wash shift
- Water inlet filter screens require cleaning to remove silt debris before every hookup
