3,500 PSI - 8.5 GPM Hot Water Pressure Washer Honda GX690 Engine and AR Triplex Pump
Extreme Flow Meets Unmatched Durability — Built for the Pros Who Work Harder
For commercial cleaning professionals who face the toughest grime, biggest messes, and tightest deadlines, the BE Power Equipment HW3524HA12V delivers unstoppable cleaning performance. Pushing out a massive 3,500 PSI at 8.5 GPM, this hot water pressure washer pairs high flow volume with the heat you need to blast away grease, oil, and buildup—fast.
At the heart of the machine is a Honda GX690 V-Twin engine with electric start, matched with a belt-driven AR triplex pump known for industrial reliability. A 12V Beckett diesel burner powers a heating coil capable of reaching up to 200°F, and the entire system is framed in a rugged powder-coated steel roll cage—ready for permanent truck or trailer mounting.
This is the pressure washer serious pros rely on when clean matters and downtime isn't an option.
Power + Heat + Volume = Unrivaled Cleaning Performance
When you're working in heavy equipment yards, sanitation zones, or construction sites, standard washers just can't keep up. The HW3524HA12V was engineered specifically for high-output environments, offering a rare combination of 3,500 PSI and 8.5 GPM—ideal for large surface areas, heavy debris, and high-throughput commercial workflows.
The 12V diesel-fired Beckett burner fires up a high-efficiency heating coil to produce hot water up to 200°F (93°C). The result? Cut through grease, oil, and stuck-on gunk in half the time. And with the adjustable thermostat and rocker switch burner control, you can quickly adapt to hot or cold water jobs.
Honda GX690: The Trusted Name in Industrial Engines
The powerplant of this unit is the Honda GX690 4-stroke V-Twin engine, known across industries for its smooth performance, low fuel consumption, and long operating life. It's engineered for durability with cast-iron cylinder sleeves, OHV design, and a high-output charging system—perfect for continuous-duty applications in the field.
Electric start functionality ensures hassle-free ignition at the push of a button. Included is a 55AH marine-grade AGM battery, built to withstand harsh jobsite conditions, vibration, and extended use.
Belt Drive System: Quiet, Efficient, Built to Last
This model features a belt drive system, reducing the pump's RPM and operational stress to significantly extend its lifespan. Lower heat and vibration levels also translate to quieter, smoother operation, ideal for all-day jobs or in areas where consistent performance is critical.
Belt-driven pumps are the gold standard in high-use commercial environments—and this one is no exception.
Industrial AR Triplex Pump: Built for Real Work
The AR (Annovi Reverberi) industrial-grade triplex pump is built to withstand years of high-pressure operation and exposure to hot water. It's engineered with premium materials and smart design to keep working long after others give out:
- Reinforced pump body for maximum durability
- Forged brass manifold resists corrosion and heat damage
- Solid ceramic plungers reduce wear, even in high-temp cleaning
- Stainless steel check valves for precision control and pressure retention
- Thermal relief valve prevents overheating and protects internal components
Paired with an external unloader, the pump runs cooler and more efficiently, giving you the performance edge and long service life your business depends on.
Purpose-Built for Truck & Trailer Mounting
The 1.5” OD powder-coated steel roll cage is designed to be bolted directly to trucks, trailers, or custom skids. It protects critical components from the elements and rough handling, while leaving everything accessible for operation and maintenance.
This frame isn't just rugged—it's smart. With its compact footprint, centralized lifting point, and modular mounting brackets, it's perfect for permanent installations in service rigs, utility trailers, or mobile wash trucks.
Smart Maintenance Features for Less Downtime
Routine maintenance shouldn't slow you down. This unit includes dedicated oil drain hoses on both the engine and the pump, making oil changes easier, faster, and cleaner without crawling under the frame.
These small details save time—and in high-volume operations, that adds up fast.
Industrial-Grade Accessories Included
The HW3524HA12V comes fully equipped with everything you need to get started on the job:
- 50-ft high-pressure hose: Heavy-duty double-braided steel wire construction for high temperature and high PSI use
