Mi-T-M CBA-3504-1MGH — Belt-Drive 3500 PSI at 4.0 GPM with Honda GX390
The CBA-3504-1MGH combines 3,500 PSI pressure with 4.0 GPM flow — the highest flow rate in the 3,500 PSI CBA range — through a General pump belt-driven by a 389cc Honda GX390 OHV engine. At 4.0 GPM, cleaning units reach 14,000 CU, placing this unit between the 3,500 PSI AR-pump variants and the 4,000 PSI / 3.4 GPM models in cleaning power per minute.
CBA-3504-1MGH General Pump and High-Flow Belt Drive
- 389cc Honda GX390 OHV with external bypass system — bypass actively recirculates water when trigger is released, preventing heat-soak in the pump head during stop-and-start cleaning cycles.
- General pump at 4.0 GPM — higher water volume per minute reduces total cleaning time versus 3.7 GPM AR-pump variants on large surface areas.
- Belt-drive two-piece guard — belt runs pump at reduced RPM; guard protects drivetrain from jobsite contamination.
- Forged brass manifold and thermal relief valve — heat protection at the manifold level in addition to the external bypass.
- Corrosion-resistant aluminum frame with vibration isolation plate — 165-lb unit; 13-inch flat-free tires for job-site mobility.
Cleaning Scenarios Where High GPM Matters
Surface area per hour is determined by GPM multiplied by pressure — not pressure alone. A pressure washer running 3,500 PSI at 4.0 GPM cleans the same square footage in less time than a 3,500 PSI / 3.7 GPM unit, while applying the same surface-safe maximum pressure. Parking structure operators washing 50,000 sq. ft. of concrete per night specify high-GPM units to meet cleaning windows within available hours. Industrial food processing plants washing drains and floors prioritize flow rate because diluting wash chemicals requires volume. Agricultural operations hosing down livestock housing benefit from 4.0 GPM for the rinse cycle where water volume matters more than pressure. ETL certified; 49-state — not for California.
