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.

Frequently Asked Questions

How does the CBA-3504-1MGH differ from other CBA-3504 models?
The CBA-3504-1MGH uses a General pump and 389cc Honda GX390 engine, producing 3,500 PSI at 4.0 GPM. The AR-pump CBA-3504 variants (1MAH, 1MAK, 1MAM) produce 3,500 PSI at 3.7 GPM. The 1MGH delivers 300 more gallons per hour, increasing area coverage per shift.
Why does the CBA-3504-1MGH have both an external bypass and a thermal relief valve?
They protect the pump in different scenarios. The external bypass recirculates water actively when the operator releases the trigger during normal cleaning cycles. The thermal relief valve is a failsafe that discharges water if the bypass is insufficient and pump temperature reaches a critical threshold.
What is the cleaning units (CU) rating of the CBA-3504-1MGH?
Cleaning units = PSI × GPM = 3,500 × 4.0 = 14,000 CU. This places the CBA-3504-1MGH ahead of 3,500 PSI / 3.7 GPM models (12,950 CU) and competitive with 4,000 PSI / 3.4 GPM models (13,600 CU) in per-minute cleaning output.
Is the external bypass system standard on the CBA-3504-1MGH?
Yes. The external bypass is standard on the 1MGH model, unlike other CBA-3504 variants where it is optional (CX-0082, must be ordered with the unit).
What pump brand does the CBA-3504-1MGH use?
A General pump — an American commercial pump brand with widespread parts and service availability. General pumps are used across Mi-T-M's premium CBA and CA series in the models that achieve 4.0 GPM output.
Is the CBA-3504-1MGH available for California buyers?
No. The 389cc Honda GX390 in this configuration is a 49-state engine that does not meet CARB standards. California buyers should contact Mi-T-M for a CARB-compliant equivalent.
