Description
Clean commercial mower fleets, construction excavators, and concrete equipment yards with high-volume industrial blast force. The Simpson Industrial Series 3500 PSI 4.0 GPM gas cold water pressure washer strips caked dirt and mud from equipment frames. This commercial pressure washer restores machinery across equipment wash bays and jobsite trailers. It cannot generate hot water for thermal oil removal.
A commercial Kohler CH440 14HP gas engine couples directly to an industrial AAA triplex ceramic plunger pump. The heavy-duty welded tubular steel roll-cage chassis protects mechanical components from impact damage on jobsite trailers. Thirteen-inch pneumatic tires on steel hub wheels navigate rough terrain, while an external unloader valve lets mechanics adjust operating pressure to protect delicate equipment paint.
Industrial Series Cold Washer Specs
Landscape maintenance crews and commercial facility managers require dependable high-pressure washers to clean mowing rigs between customer jobsites. This machine delivers continuous washdown performance.
- Kohler CH440 14HP commercial engine delivers high mechanical pump drive power
- AAA industrial triplex plunger pump generates 3500 PSI at 4.0 GPM for deep cleaning force
- Welded tubular steel roll-cage frame protects engine and pump from heavy jobsite impacts
- Five quick-connect spray tips supply zero, fifteen, twenty-five, forty-degree, and soap fans
- Thirteen-inch pneumatic tires roll smoothly across uneven gravel parking lots and muddy turf
- External unloader valve allows manual pressure tuning to match sensitive equipment surfaces
- Detergent siphoning hose draws chemical soaps into low-pressure spray streams smoothly
Pump Dyno Pressure Telemetry Testing
Dynamometer testing records continuous 3500 PSI discharge pressure at 4.0 GPM water flow at 3450 engine RPM. The Kohler CH440 engine burns 0.82 GPH fuel under full washing load. Pump manifold temperature rise stabilizes at 26 degrees Fahrenheit above inlet water temperature after two hours of continuous washing. Sound pressure meters record 88 dBA at twenty feet distance.
Equipment Washing Safety Boundary Limits
Check engine and pump oil levels, connect pressurized water lines, purge air bubbles from the wand, pull the recoil rope, and squeeze the spray trigger. Keep spray nozzles twelve inches away from machine paint. Do not spray high-pressure streams directly at unsealed engine electrical harnesses.
- Engine crankcase oil demands checking and topping off before starting every washing shift
- Pump crankcase oil requires replacement with non-detergent pump oil every hundred hours
- Water inlet filter screens require cleaning to remove sand sediment before every water connection
