The BE Pressure B4013HCS is a 4,000 PSI / 4.0 GPM cold-water gas pressure washer built for contractors who clean for a living. A 389cc Honda GX390 engine drives a Comet ZWD-K-4040G triplex pump on a powder-coated steel frame, putting commercial output in a unit small enough to load into a service truck. Deck and concrete contractors, fleet washers, building exterior crews, and farm and ranch operators reach for this class of machine when residential-grade units stop being economical.
Use cases
- Concrete driveways, sidewalks, and patios with surface cleaner attachments
- House washing and deck restoration for residential exterior contractors
- Fleet vehicle and trailer wash-down for trucking and equipment-rental operations
- Farm equipment, tractor, and barn cleaning where 4 GPM rinse capacity saves real time
- Graffiti removal and parking-garage cleaning for commercial property managers
- Heavy-equipment cleaning at construction yards and rental shops
What makes the B4013HCS different
The Comet ZWD-K-4040G is a forged-brass-manifold triplex pump engineered for daily duty. The thermal-release valve protects the pump in bypass, the die-cast aluminum body sheds heat under sustained use, and the one-piece ceramic plungers extend service intervals. Pair that with a Honda GX390 commercial engine and you get a unit that survives the daily start-stop cycle of contract route work rather than the once-a-month weekend duty of a homeowner machine.
Frequently asked questions
Will this pump survive long bypass periods on a typical job?
The thermal-release valve on the Comet ZWD opens when pump temperature climbs in bypass and discharges hot water, protecting the seals. Standard practice is still to trigger the gun every couple of minutes during long pauses, but the thermal release is your safety net.
What water supply do I need to feed 4 GPM?
A standard 5/8-inch garden hose at full flow handles 4 GPM from a residential spigot. For long inlet runs or low-flow wells, use a 3/4-inch hose or feed from a buffer tank to keep the pump from cavitating.
Does this machine work with surface cleaners?
Yes. A 4 GPM machine pairs well with 16 to 20-inch surface cleaners. Match the surface cleaner's PSI rating and combined nozzle GPM to the B4013HCS output (4 GPM at 4,000 PSI) for full coverage on concrete and flatwork.
Is the engine pull-start or electric-start?
The Honda GX390 in the B4013HCS is recoil (pull) start. That is the standard configuration on this class of contractor unit; electric-start options are available on larger frame models.
How often should I service the pump and engine?
Honda recommends oil change at 20 hours after initial break-in, then every 100 hours. The Comet pump should be checked for oil clarity weekly under daily use; pump oil change every 500 hours or annually, whichever comes first. Always run pump saver or antifreeze before storage in freezing climates.
