JP-3504-3MMB Gas Pressure Washer — JP Series 3500 PSI with Mi-T-M OHV Engine

The JP-3504-3MMB produces 3500 PSI at 3.5 GPM — 12,250 cleaning units — from a 420cc Mi-T-M OHV engine paired with an AR crankshaft pump.

JP-3504-3MMB Cleaning Output and Engine Comparison

The Mi-T-M OHV engine suits buyers whose preferred repair shop stocks Mi-T-M parts or who want uniform engine inventory across a multi-unit fleet.

  • 3500 PSI at 3.5 GPM (12,250 CU) — removes heavy mud, road film, and oxidized paint from equipment without multiple passes
  • 420cc Mi-T-M OHV engine — direct factory parts support; matches fleets already running Mi-T-M power equipment
  • AR crankshaft pump, forged brass manifold — crankshaft geometry handles sustained daily operation better than axial designs
  • Thermal relief valve and in-line water strainer — protects pump from heat build-up when trigger is held closed and from particulates in supply water
  • 50-ft × 3/8-in non-marking hose, 48-in lance — longer lance reduces back strain; 50-ft reach covers most trailer and box truck lengths
  • Powder-coated steel frame, 10-in flat-free tires — withstands job-site impact; tires never need inflation mid-shift

Agricultural producers wash combines, sprayers, and grain trailers at season end. Property maintenance contractors clean parking decks, loading docks, and building facades.

Frequently Asked Questions

What does 12,250 cleaning units mean for the JP-3504-3MMB?
Cleaning units (CU) = PSI × GPM. Higher CU means fewer rinse passes on heavily soiled surfaces like muddy equipment or road-filmed trucks.
Is the JP-3504-3MMB AR pump an axial or crankshaft design?
The AR pump on the JP-3504-3MMB is a crankshaft design. Crankshaft pumps use a separate bearing assembly that keeps the pump oil isolated from engine heat, allowing sustained operation in daily commercial use. Axial pumps share a shaft with the engine and are better suited for lighter-duty intermittent use.
What accessories are included with the JP-3504-3MMB?
The JP-3504-3MMB includes three quick-connect nozzles (0°, 15°, 25°), a 50-ft × 3/8-in non-marking high-pressure hose, a 48-in lance, and an insulated trigger gun. The Mi-T-M adjustable pressure unloader is installed on the pump.
What is the thermal relief valve on the JP-3504-3MMB?
The thermal relief valve automatically releases a small amount of hot water when the trigger is closed for extended periods, preventing heat build-up in the pump head. This protects the pump seals and pistons from damage during idle periods on job sites.
