Mi-T-M CW-4004-5MGH Belt Drive Pressure Washer – 4000 PSI, 3.5 GPM, Honda GX390
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.
