3,200 PSI 5.5 GPM Truck Mount Cold Water Gas Pressure Washer with Honda GX390 Engine and CP Belt Drive Triplex Pump - B3213HTBAS

3,200 PSI 5.5 GPM Truck Mount Cold Water Gas Pressure Washer with Honda GX390 Engine and CP Belt Drive Triplex Pump

The BE Power Equipment B3213HTBAS Truck Mount Pressure Washer is engineered for professional operators who require a fixed, high-flow cleaning solution mounted directly to a truck or trailer. Delivering 3,200 PSI at 5.5 GPM, this industrial-grade pressure washer provides exceptional water volume and consistent pressure for demanding commercial and industrial cleaning applications where mobility and reliability are critical.

Powered by a proven Honda GX390 389cc recoil start engine and paired with an industrial-grade CP CTB4S P8 belt-driven triplex pump running at 1,450 RPM, the B3213HTBAS is designed for continuous operation in professional environments. Mounted on a powder-coated steel plate with integrated anti-vibration pads, this unit bolts directly to a truck or trailer, creating a stable, secure cleaning platform built for daily use.

Whether you're running a mobile pressure washing business, servicing commercial properties, or maintaining equipment and fleets, the B3213HTBAS delivers the flow, durability, and performance professionals depend on.

Built for Serious Truck Mount Pressure Washing

This pressure washer is built specifically for truck and trailer mounting, providing a permanent cleaning solution that's always ready to work. Designed for commercial and industrial environments, the B3213HTBAS is ideal for:

• Mobile pressure washing businesses
• Fleet and equipment washing
• Commercial property maintenance
• Agricultural and industrial cleaning
• Large-area surface cleaning where high water volume is essential

With 5.5 GPM of water flow and steady pressure, this truck mount unit excels at rinsing, surface cleaning, and large-area washing where volume matters just as much as pressure.

Features

Honda GX390 Engine

At the core of this truck mount pressure washer is the Honda GX390 389cc recoil start engine, a commercial-grade overhead valve engine known for durability, reliability, and long service life. Key engine features include:

• Reliable recoil start and smooth operation
• High-torque output suited for belt drive applications
• Automatic low-oil shutdown to protect the engine
• Fuel-efficient OHV design for extended runtime
• 6.1 L / 1.6 GAL fuel tank for extended operation between refueling

The Honda GX390 engine is covered under Honda's separate engine warranty program.

Belt Drive System for Extended Pump Life

The B3213HTBAS uses a gas belt drive system to power the CP triplex pump, running the pump at 1,450 RPM — significantly lower than direct drive configurations. This lower operating speed reduces heat buildup and minimizes pump wear for sustained continuous-duty operation:

• Reduced heat buildup during extended operation
• Lower pump wear for extended service life
• Smoother, more consistent pressure output at high flow rates
• Improved reliability for high-frequency professional use

Industrial-Grade CP CTB4S Triplex Pump with External Unloader

Paired with the Honda engine via the belt drive system is an industrial-grade CP CTB4S P8 class triplex pump with external unloader and adjustable injector. Key pump features include:

• P8 industrial pump class for demanding continuous-duty applications
• Belt drive operation at 1,450 RPM for reduced wear and extended service life
• Thermal relief valve to prevent overheating during extended bypass operation
• Smooth, consistent pressure delivery at 3,200 PSI and 5.5 GPM

External Unloader with Adjustable Injector

The external unloader regulates water flow and pressure when the trigger gun is released. It can be set to dump-to-ground bypass to maximize pump cooling during extended operation — essential for sustained mobile pressure washing use. The adjustable injector allows detergent concentration to be dialled in to match different surfaces and cleaning applications.

238 Truck Mount Belt Drive Frame with Anti-Vibration Design

The B3213HTBAS is mounted on the 238 Truck Mount Belt Drive Dealer Frame — a powder-coated steel plate purpose-built to bolt securely through to a truck or trailer frame. Integrated anti-vibration pads reduce movement and stress on components during operation and transport, improving stability and extending equipment life. The mounting design accommodates the belt drive system while keeping the unit compact at 29" x 20" x 20".

50-Foot x 3/8" Steel Braided High-Pressure Hose

The included 50' x 3/8" QC single wire braided rubber hose provides durability and extended reach for cleaning around vehicles, equipment, and job sites without repositioning the truck. The 3/8" diameter supports the full 5.5 GPM flow rate of this unit.

36" Insulated Spray Wand and Trigger Gun

A 36" QC insulated spray wand allows operators to clean hard-to-reach areas with improved control and reach. The insulated design reduces heat transfer during prolonged use, and the quick-connect system makes nozzle changes fast and straightforward.

4 Quick-Connect Spray Nozzles

Four quick-connect nozzles cover the full range of cleaning applications:

• 15°: Heavy-duty cleaning and surface stripping
• 25°: General-purpose washing
• 40°: Rinsing or cleaning delicate surfaces
• Soap: Applying detergents and degreasers through the adjustable injector

Safety Features

• Automatic low-oil shutdown: Turns off the engine if oil drops below a safe operating level
• Thermal relief valve: Releases built-up heat from the pump during extended idle or bypass operation

Warranty and Factory Testing

The B3213HTBAS is backed by a 3-year limited warranty from BE Power Equipment. The Honda GX390 engine is covered separately under Honda's manufacturer warranty program.

Each unit is functionally tested at the factory before shipping. Units may contain minimal residual oil or fuel odor, confirming that the machine has passed quality inspections and is ready for installation and use.
