+1 (978) 295-7538JP-3504-3MKB Gas Pressure Washer — JP Series 3500 PSI, 3.5 GPM with Kohler CH440
The Mi-T-M JP Series JP-3504-3MKB is the Kohler-powered version of the JP 3,500 PSI platform, pairing the same AR crankshaft pump and JP frame with a 429cc Kohler CH440 OHV engine. Output is identical to the Honda and Mi-T-M engine variants: 3,500 PSI at 3.5 GPM, 12,250 cleaning units. The Kohler CH440 is the largest single-cylinder in Kohler's CH commercial series, used in heavy-load outdoor power equipment — its full-pressure lubrication system is rated for longer duty cycles than splash-lube designs at this displacement.
JP-3504-3MKB Kohler CH440 Engine and Pump System
The CH440's full-pressure lubrication is a meaningful specification for sustained daily operation — it maintains oil pressure to bearing surfaces regardless of operating angle or load fluctuations.
- 3,500 PSI at 3.5 GPM (12,250 CU) — same output as Honda and Mi-T-M variants; engine choice does not affect pump output
- 429cc Kohler CH440 OHV engine — Kohler's largest CH-series single; full-pressure lubrication, cast-iron sleeve, commercial warranty
- AR crankshaft pump — triplex ceramic plunger; rated for sustained high-output operation at 3.5 GPM and 3,500 PSI
- 48-inch lance, 50-foot non-marking hose — extended reach for fleet vehicles and large equipment from one position
- 10-inch flat-free tires, 40-inch powder-coated steel frame — job site rated; 142 lbs requires two-person trailer loading
- Adjustable pressure unloader — scale output pressure down for vehicle washing without nozzle changes
JP-3504-3MKB Applications and Environments
Municipal equipment yards, agricultural cooperatives, and construction operations that run Kohler-powered equipment benefit from consolidated engine purchasing with this model. The CH440's full-pressure lubrication makes it a practical choice for machines running 4–6 hour daily wash cycles — the lubrication system sustains oil pressure under sustained high-torque load better than splash-lube engines at the same displacement. Fleet washing operations cleaning semi-trucks, tankers, and construction equipment get 12,250 CU throughput from a machine that integrates with their existing Kohler service program.
