Overview
The Diesel Pressure Cleaner is a Kohler powered 4 wheel cart machine delivering 4000 PSI at 12 litres per minute. A Kohler 12HP KD15 440 engine with electric stop drives a Comet RW3540 premium plunger pump through a gearbox at 1450 RPM, and the machine runs on a black powder coated roll frame. It is manufactured in Australia and conforms to the PESA 2017 emissions standard.
The combination of 4000 PSI with a 12 litre flow sits in the sweet spot for plant cleaning: enough pressure to shift baked on grease and grime, with a flow rate that still gives a strong cutting stream. The gearbox drive keeps the pump turning slowly and cool, which is what makes the pump last in daily commercial use.

Frequently Asked Questions
How does the gearbox drive help?
The pump runs at 1450 RPM through a gearbox instead of spinning at engine speed. Lower, steady pump speed means less heat and vibration, which is what extends the life of the pump in commercial use. It is a standard feature on machines built for daily work.
What is the water requirement?
The machine needs a constant water supply from a tap or tank. At 12 litres per minute it draws less water than the 21 litre machines, so it suits sites where water supply is moderate. Use a good quality inlet hose with a filter to keep debris out of the pump.
Is it supplied ready to run?
Yes. It comes with 15 metres of high pressure hose, four quick connect nozzles, a gun and lance, and is supplied ready to go once the engine has been serviced and fuelled. The battery and electric start are part of the machine.
