+1 (978) 295-7538Mi-T-M CBA-4004-1MCH — Belt-Drive 4000 PSI at 3.7 GPM with CAT Pump
The CBA-4004-1MCH delivers 4,000 PSI at 3.7 GPM — the highest flow rate in the 4,000 PSI CBA range — using a CAT pump belt-driven by a 389cc Honda GX390 OHV engine. At 14,800 cleaning units, it out-produces the 3.4 GPM AR-pump CBA-4004 variants by 1,200 CU per minute on the same surface area. At 156 lbs., it's 9 lbs. lighter than other CBA-4004 models.
CBA-4004-1MCH CAT Pump, External Bypass, and Performance Edge
- CAT pump at 4,000 PSI / 3.7 GPM — Californian-manufactured pump brand used across industrial pressure washing; forged brass manifold and external bypass system standard.
- 389cc Honda GX390 OHV engine — Pressure Relief Start; belt drive runs pump below engine RPM for lower operating temperature.
- External bypass system standard — actively recirculates water when trigger is released, preventing heat buildup that damages seals.
- Thermal relief valve and clear-sleeve water filter — secondary heat protection; filter checks in under 30 seconds.
- Corrosion-resistant aluminum frame at 156 lbs. — 9 lbs. lighter than the AR-pump CBA-4004 models; 13-inch flat-free tires.
High-Flow Industrial Cleaning Applications
At 3.7 GPM, the CBA-4004-1MCH applies more water volume per minute than the 3.4 GPM CBA-4004 variants — a meaningful difference when cleaning large areas like concrete parking decks, industrial equipment bays, and livestock facilities. The external bypass standard on this model makes it better suited to stop-and-start cleaning patterns — such as working around equipment and obstacles — without risking pump damage from heat soak. Painting contractors use the combination of 4,000 PSI and 3.7 GPM for wet media blasting prep and paint stripping on large metal structures where both pressure and flow are required. ETL certified; 49-state — not for California.
