+1 (978) 295-7538CA-4004-1MCM Gas Pressure Washer — CA Aluminum Series 4000 PSI, 4.0 GPM with Mi-T-M OHV
The CA-4004-1MCM produces 4000 PSI at 4.0 GPM — 16,000 cleaning units — from a 420cc Mi-T-M OHV engine paired with a CAT crankshaft pump on Mi-T-M's 128-lb aluminum frame.
CA-4004-1MCM High-Flow Configuration and Single-Brand Support
The CAT pump supports the 4.0 GPM flow rate with an integrated external bypass system, protecting the pump from heat build-up during trigger-closed idle without requiring a separately ordered accessory. The 420cc Mi-T-M OHV engine provides the displacement needed to sustain 4.0 GPM at 4000 PSI under continuous commercial operation.
- 420cc Mi-T-M OHV engine — Mi-T-M's highest-displacement OHV; engine and pump supported by Mi-T-M dealer network for single-source service
- CAT crankshaft pump with integrated external bypass — CAT rated for sustained high-flow commercial use; external bypass included as standard equipment
- Vibration isolation plate, 50-ft hose, 48-in lance — vibration dampening extends pump seal life; 48-in lance handles elevated and large-equipment surfaces
- Integrated external bypass — no separate accessory needed — protects CAT pump from heat at sustained 4000 PSI; standard on all 1MCM configurations
CA-4004-1MCM Applications and Environments
Mi-T-M fleet operators who want unified service for both engine and pump at the highest available portable output choose the CA-4004-1MCM. Industrial cleaning operations use the 16,000 CU output for large-footprint equipment pads, production floors, and machinery with accumulated heavy contamination from oils, process chemicals, and particulates. Construction companies apply it to large concrete form arrays and equipment staging areas. Property restoration firms use it for wide masonry cleaning before recoating on commercial building projects.
