Mi-T-M CW-4004-5MGH: 4000 PSI Honda GX390 Belt Drive Pressure Washer with Nickel-Plated Manifold

The Mi-T-M CW-4004-5MGH delivers 4000 PSI at 3.5 GPM through a Honda GX390 OHV 389cc engine and General pump with nickel-plated brass manifold and external bypass system. The nickel-plated manifold — standard on 4000+ PSI CW Premium models — provides enhanced corrosion resistance and surface hardness compared to standard brass for extended service life in high-pressure sustained cycles. The 216 lb unit operates on 13-inch flat-free tires with 48-inch lance and factory preset unloader for immediate field use.

CW-4004-5MGH Pump and High-Pressure Manifold Detail

  • Nickel-plated brass manifold at 4000 PSI — harder surface finish resists corrosion from detergent chemicals and high-pressure water impingement
  • General pump with external bypass system — continuous bypass during trigger-off maintains pump cooling at 4000 PSI operating load
  • Honda GX390 OHV 389cc, 11.7 gross HP — recoil start with Honda commercial engine warranty and nationwide dealer coverage
  • Thermal relief valve and clear-sleeve water filter — dual-protection system for pump internals during sustained high-pressure operation
  • Two-piece enclosed belt guard on powder-coated frame — belt alignment protection during field transport to and between jobsites

High-Pressure Applications for 4000 PSI, 3.5 GPM Output

Concrete contractors cleaning and etching slabs before epoxy coating use 4000 PSI to open surface pores and remove laitance in the same pass. Industrial equipment rental companies cleaning returned machinery with hardened concrete and compacted soil around undercarriages reduce cleaning time significantly at 4000 PSI vs. 3000 PSI. Restoration contractors preparing masonry and concrete surfaces for sealer application find 4000 PSI removes decades of embedded contamination without surface mechanical abrasion. The 50-foot non-marking hose and 48-inch lance provide working reach across most standard construction site configurations.

Included Components and Available Options

Ships with quick-connect nozzles (0°, 15°, 25°, 40°), a 50-foot x 3/8-inch non-marking hose, and an insulated trigger gun. Factory options available for CW-4004 series. Not for sale in California.

Frequently Asked Questions

What is the cleaning output of the CW-4004-5MGH?
4000 PSI at 3.5 GPM — 14,000 cleaning units. The higher PSI vs. the CW-3504 makes it more effective for hardened concrete, epoxy surface prep, and heavily soiled industrial equipment.
What is a nickel-plated brass manifold and why does this model have one?
Nickel plating adds a harder, more corrosion-resistant surface to the brass manifold. Mi-T-M uses nickel-plated manifolds on 4000+ PSI models because detergent chemicals and sustained high-pressure water impact accelerate surface wear on standard brass at that pressure range.
What engine powers the CW-4004-5MGH?
Honda GX390 OHV 389cc at 11.7 gross HP with recoil start. Honda's GX series carries a commercial engine warranty and is supported by Honda's nationwide dealer network.
How does the external bypass protect the pump at 4000 PSI?
The external bypass continuously recirculates water at the pump inlet when the trigger is disengaged, preventing the elevated heat generated at 4000 PSI from degrading pump seals during idle intervals.
Is the CW-4004-5MGH suitable for concrete surface preparation?
Yes — 4000 PSI with a 15° or 0° nozzle is used by concrete contractors for surface etching before epoxy coating, removing laitance, and cleaning joints before sealing at controlled distances of 6 to 12 inches.
Is this model available in California?
No — not for sale in California due to Honda GX390 engine CARB compliance requirements. California buyers need a CARB-compliant Mi-T-M model.
What does this unit ship with?
Quick-connect nozzles (0°, 15°, 25°, 40°), a 50-foot x 3/8-inch non-marking hose, and an insulated trigger gun rated for 4000 PSI are included. Net weight 216 lbs; freight delivery only.
