4,200 PSI Honda Power Driving a Premium CAT Triplex Pump
The BE Power Equipment B4213HSJS mates a Honda GX390 engine to a CAT 66DX40G1 triplex pump — one of the most respected names in high-pressure pumps — for a full 4,200 PSI at 4.2 GPM of cold-water cleaning power. This commercial gas pressure washer is built for operators who want a premium, rebuildable pump platform under a proven Honda pressure washer.
It’s a machine sized for people who clean for a paycheck: contractors on concrete and hardscape, fleet crews cutting grease and road film off rigs, and facilities teams handling barns, lots, and heavy outdoor upkeep. With a 0° blasting nozzle, an adjustable soap injector, and direct drive off the Honda engine, this gas powered pressure washer holds its pace shift after shift.
Key Features
-
4,200 PSI at 4.2 GPM — commercial cold-water output that turns hours of scrubbing into a single pass.
-
CAT 66DX40G1 triplex pump — a premium, fully rebuildable industrial pump prized for long service life under heavy daily duty.
-
Honda GX390 engine (389cc) — the industry benchmark for easy starts and pressure that never sags mid-job.
-
Zero-degree blasting nozzle included — a concentrated 0° tip for stubborn coatings, plus 15°, 40°, and soap for everyday work.
-
Adjustable downstream soap injector — meter detergent draw to match the job, then switch straight back to high-pressure rinse.
-
50 ft × 3/8 in steel-braided hose — reach across a lot or around a rig without repositioning the machine.
-
36 in insulated gun and wand — comfortable grip and reach through long cleaning sessions.
-
Powder-coated steel frame with flat-free tires — onboard accessory storage and never-flat wheels roll over gravel, curbs, and rough ground.
Fuel, Water, and Unloading
✔︎ Regular unleaded gasoline (86 octane, up to 10% ethanol) — the Honda GX390 takes SAE 10W30; check the oil before every start.
✔︎ A steady water feed of at least 4.2 GPM from a standard garden hose and spigot keeps the CAT pump cool and healthy.
✔︎ Cold water only on this model; draw detergent through the adjustable downstream injector for wash-and-rinse cycles.
✔︎ Use the 0° blasting nozzle with care — keep it moving and off soft surfaces to avoid gouging.
✔︎ Ships freight on a pallet at 147 lbs boxed — line up a liftgate or a second set of hands to unload.
