If you’re up against extreme dirt, you need an extreme pressure washer to handle the task. That’s where a diesel pressure washer comes in.

With all the advantages of a diesel engine, today’s diesel pressure washers are designed to get the toughest commercial cleaning jobs done in a fraction of the time. Need a dairy shed cleaned out? Tick. Washing down greasy industrial machinery? Tick. Cleaning mining equipment? Tick, tick, tick.

Before we reveal the top models on the market, let’s look at the pros of buying a diesel pressure washer. Compared to electric or petrol pressure washers, diesel models have a lot to offer – especially for mine sites and industrial applications:

Diesel pressure washers are more fuel efficient.

Hands down, one of the biggest advantages of a diesel engine is fuel efficiency. If you compare a diesel pressure washer with a petrol equivalent, the higher compression of a diesel engine means it goes further.

Diesel pressure washers have a lower cost of ownership

Ever wondered why big industries rely on diesel fuel to run their business? Whether you’re talking about generators, tractors, bulldozers, excavators or pressure washers, diesel engines last longer and cost less to run. The reason is simple: diesel engines don’t work as hard as petrol engines to get the same power output. Engine parts are under less stress, so they are less likely to break down. And diesel fuel is self-lubricating, meaning the fuel delivery system should also last longer than the petrol equivalent.

There are lots of added extra options

Many diesel pressure washers can be fully equipped with things like fuel tank bunding, fire extinguisher, safety stop, and other mine specifications needed on site. Some can be optioned with a long-range fuel tank and an electric start too.

 Ideal for heavy industrial and mining applications

All of the above means that diesel pressure washers are a good choice for heavy industrial and mining applications.

WHAT TO LOOK FOR IN A DIESEL PRESSURE WASHER

Higher PSI

Pay attention to the PSI. PSI means pounds per square inch, which tells you the cleaning pressure of the washer. When it comes to cleaning greasy industrial spaces and machinery, look for a PSI of 3000-5000.

Quality pump

With all the high-pressure water coming through the pump, you need a strong and durable pump that won’t break down easily. Some manufacturers, like Crommelins, offer a separate warranty for the pump.

Reputable brand

Choosing a quality brand means you can be sure your diesel pressure washer is made with the best quality engines and components. Plus, you’ll be backed by national service and spare parts networks for any warranty and service requirements.
