8.5 GPM 3500 PSI Hot Water Pressure Washer Honda GX690 Engine AR XW3028N

8.5 GPM 3,500 PSI GPM Hot Water Pressure Washer with Honda GX690 Engine and Annovi Reverberi Triplex Pump 

Double the Flow. Built for Extreme Demands. Ready for the Road.

Designed for heavy-duty, continuous-use applications, this 8.5 gpm 3,500 psi hot water pressure washer delivers powerful cleaning flow, exceptional heat performance, and long-lasting durability in a mobile-ready frame that’s engineered for truck or trailer mounting.

Powered by a Honda GX690 V-twin engine with electric start, and paired with a belt-driven AR XW3028N industrial-grade triplex pump, this unit is all about reliability, performance, and efficiency. The 12V Beckett diesel burner heats water up to 200°F (93°C) to cut through grease, oil, and thick grime, while a steel roll cage and premium components ensure you’re ready for the toughest jobs, every time.

Why High Flow + Heat Matters

Not all pressure washers are built the same. When you're cleaning large surfaces, flushing heavy debris, or degreasing equipment in bulk, high flow volume (8.5 GPM) is just as important as high pressure. Add hot water up to 200°F, and you have the ultimate cleaning solution for high-output applications like fleet washing, food and beverage plants, industrial sites, and agricultural operations.

The 12V Beckett burner delivers high-efficiency diesel heating that powers through tough buildup and oil, drastically reducing cleaning time and detergent usage. Controlled by an adjustable thermostat, you can fine-tune water temperature to the task at hand—or turn the burner off entirely for cold water use.

Premium Honda GX690 Engine with Electric Start

At the core of the skid is the Honda GX690—the top-tier V-twin engine in Honda’s commercial lineup. With electric start and a 55AH marine-grade AGM battery included, it delivers consistent ignition and quiet, powerful operation for extended use in the field.

Honda’s advanced OHV technology, low fuel consumption, and high output make it a smart choice for pro users who value long service life and minimal downtime. From construction yards to mobile wash fleets, the GX690 is trusted by pros for a reason.

Belt Drive = Long Pump Life + Smooth Power Delivery

This unit features a belt-driven system that significantly reduces pump RPM, vibration, and wear. By lowering the working stress on the pump, the belt drive increases longevity and improves cooling—making it ideal for continuous, high-demand use.

The belt system also helps isolate engine vibration from the pump itself, protecting key components and reducing noise levels during operation.

Industrial Annovi Reverberi Triplex Pump: Built for Maximum Durability

Designed for the most extreme conditions, the Annovi Reverberi triplex pump on this unit includes premium internal construction to ensure performance under pressure:

• Reinforced body for structural strength

• Forged Nickel plated brass manifold for corrosion resistance

• Solid ceramic plungers for temperature and chemical resistance

• Stainless steel check valves for precision and long life

• Thermal relief valve to prevent overheating

This pump is built to handle hot water, heavy use, and fluctuating field conditions without faltering. The external unloader improves temperature control and pressure stability, further increasing component life and adaptability.

Hot Water System Powered by Beckett Burner

The 12V diesel-fired Beckett burner powers a robust heating coil that delivers 200°F of cleaning energy with industry-grade efficiency. A rocker switch allows you to turn the burner on or off instantly, while the adjustable thermostat lets you select the ideal temperature for each job—no more wasting time with manual guesswork.

From degreasing engines to sanitizing livestock enclosures, the hot water system gives you unmatched control over your cleaning capabilities.

Designed for Mobile Mounting and Harsh Work Environments

Built for truck and trailer integration, the 1.5" OD powder-coated steel frame is reinforced with a full roll cage design to protect the engine, burner, and pump. This frame offers full accessibility for operation and service, while providing structural integrity for mobile and off-road environments.

Whether mounted on a wash rig, skid trailer, or work truck, the hot skid is purpose-built to handle bumps, vibration, and tough terrain without compromise.

Simplified Maintenance That Saves You Time

For added convenience, the unit features oil drain hoses on both the engine and pump. This small but significant upgrade lets you perform clean, fast oil changes without removing covers or crawling beneath the frame.

Routine maintenance is faster, cleaner, and safer—keeping your crew moving and your machine in peak condition longer.

Fully Loaded with Industrial Accessories

Everything you need is included for fast setup and high-efficiency cleaning:

• 50-ft high-pressure hose: Double-braided steel wire for durability and high-temperature compatibility

• 47" Spray gun and wand assembly: Insulated for heat protection and extended-use comfort

• Five quick-connect nozzles: Switch between 0°, 15°, 25°, 40°, and soap spray patterns instantly

Every connection is quick-connect equipped, so you can change nozzles, guns, or hoses on the fly with zero hassle.
