Engineered for Real-World Performance

The Centurion P2 gives you the best of both worlds: compact design and powerful output. With 3400 PSI of pressure and 2.5 gallons per minute, this pump packs enough cleaning punch to blast away dirt, grime, grease and all the rest from driveways, decks, vehicles, and equipment - all while maintaining a smooth flow.

Its axial cam design means maximum efficiency, converting engine rotation into pumping action with minimal friction and no unnecessary complications. This means less to worry about when it comes to maintenance, and a pump that just keeps on performing.

Whether you're cleaning up residential properties, farm equipment or commercial surfaces, the P2 has got you covered - day in, day out, season after season.

Axial Pump Design: The Easy, Efficient Way to Clean

The axial pump style - fewer moving parts means less to go wrong, which is exactly what you want in a cleaning pump. The pistons move in a circular motion around a wobble or swash plate that drives them back and forth, creating water pressure with a minimum of fuss.

This design is ideal for users looking for reliability and cleaning power without the complexity of trouble-prone systems. The Centurion P2's axial configuration keeps things simple, durable and long-lasting, providing years of dependable use with minimal upkeep.

The stainless steel plungers in the P2 resist corrosion, wear, and heat - maintaining performance over time, even in tough conditions. Combine this with the precision-milled aluminium manifold, and you get reliable output and efficient cooling for a longer service life.

Direct Drive: Smaller, Lighter, More Efficient

With its direct-drive setup, the Centurion P2 mounts directly onto the gas engine's crankshaft - no pulleys or belts needed. This means a smaller, lighter, more efficient system with fewer moving parts and less vibration.

The 3/4-inch hollow shaft makes it compatible with most horizontal-shaft gas engines commonly used in pressure washers - models from Honda, Kohler, Powerease and Briggs & Stratton to name a few. The result is a smooth-running, powerful cleaning system that's a cinch to install and maintain.

At just 7.5 lbs, the P2 is light enough for portable use, yet strong enough to deliver the high-pressure power needed for serious cleaning.

Built-in Unloader for Smooth, Safe Operation

The Centurion P2 comes equipped with a built-in unloader to keep things running smoothly and safely. No need for additional setup or maintenance - just plug it in and go.The Centurion P2's built-in unloader valve is a key safety and performance feature. The moment you release the spray gun trigger, the unloader kicks in and redirects water flow inside the pump , letting off steam and stopping internal damage in its tracks.

Not only does this protect the pump from getting blown out by pressure spikes and overheating, but it also extends its overall lifespan. It's a clever design that keeps things simple - fewer connections and leak points - making it a breeze to set up and keep running reliably.

The unloader's built-in pressure control ensures that the P2 starts up smoothly and delivers consistent pressure, making it one of the most user-friendly and low-maintenance high-pressure pumps out there.

Fixed Chemical Injection Port

For tougher cleaning jobs, the fixed soap injector pulls detergent directly into the water stream at low pressure. All you need to do is pop a nozzle on and you've got yourself a high-pressure wash system that can handle soap, degreasers or sanitizers with ease - perfect for washing vehicles, siding, decks or any equipment that needs a serious clean.

The chemical injection system is pre-installed and all set to go - just switch to a low-pressure nozzle and you've got reliable detergent delivery every time. This gives you versatility and efficiency in one neat package.

Thermal Relief Valve for Pump Protection

The Centurion P2 has a thermal relief valve (85.300.022) to guard against overheating - one of the most common reasons for high-pressure pump failure.

When you're running idly with the trigger released, water can heat up fast. The thermal relief valve automatically kicks in to release the hot water and bring in some cool water - just the job for stopping internal seal damage and keeping things safe and sound.

This vital safety feature adds an extra layer of reliability and gives you peace of mind - knowing that your pump will stay in top condition even on long or intermittent cleaning sessions.

Precision-Built for Durability

Every single bit of the Centurion P2 has been designed with strength and endurance in mind. The stainless steel plungers are precision machined to keep things tight and smooth and won't warp or get damaged under high pressure. The aluminum manifold is super-light, but also offers rock-solid corrosion resistance and thermal stability.

The oil-lubricated crankcase keeps things running smoothly - reducing friction and heat build-up. With a 2.2 fl oz capacity and 30W non-detergent oil, you can be sure of optimal lubrication for long life and consistent performance.

Even under the toughest conditions - from searing heat to heavy daily use - the P2 stays cool, quiet and efficient - no fuss at all.

Ideal for Residential and Light Commercial Use

The Centurion P2 is the perfect all-rounder - capable of tackling all sorts of cleaning tasks from home maintenance to light-duty commercial work. With 3400 PSI pressure and 2.5 GPM flow rate, it's got the oomph to handle both delicate and heavy cleaning jobs with ease.

Frequently Asked Questions about Pressure Washers

How to store a pressure washer?

To ensure the durability of your heavy duty pressure washer:

  • Empty the gas tank to prevent fuel from degrading or clogging the engine.
  • Empty the pump and hoses of any remaining water.
  • Perform necessary maintenance before storage.
  • Store in a dry area.
  • Cover.

What is a pressure washer?

A power washer is a cleaning machine that uses a gasoline engine to power a high pressure water pump and nozzle. It’s used to clean driveways, decks, vehicles, outdoor furniture and more by spraying water at high PSI to remove dirt, grime, mold and other debris.Many models also come with a detergent tank for added cleaning power.

How does a power washer work?

A power washer works by drawing water from a connected hose and pumping it through a high pressure nozzle. The gas engine powers the pump which pressurizes the water and then expels it through the nozzle at high speed to clean the surface. The water pressure is measured in PSI (pounds per square inch) and the flow rate is measured in GPM (gallons per minute).Many models also feature adjustable water pressure settings to cater to different cleaning needs. BE makes pressure washing easy with models available for light jobs and heavy duty commercial cleaning projects.

Gas vs Electric power washers?

The main difference is that a gas pressure washer, known for its cleaning power, is powered by a gasoline engine, making it more powerful and portable, while an electric pressure washer is powered by electricity and is generally quieter and lighter.

Gas pressure washers are for heavy duty and large areas due to their durability, whereas electric pressure washers are for smaller jobs.

Your BE electric pressure washer is perfect for smaller jobs and built for portability, and we offer a wide range of electric models. Included with our electric models is a long extension cord for use anywhere around your house.

What to consider?

When choosing a gas pressure washer consider:

  • Pressure (PSI): More PSI means more cleaning power but also more potential for damaging delicate surfaces.
  • Flow Rate (GPM): More GPM means faster cleaning as more water is dispensed.
  • Engine Power: Bigger engines mean more durability and power.
  • Portability: Weight, handle design and wheel size for easier to move.
  • Nozzles: Multiple spray nozzles to adjust the spray pattern for different tasks.
  • Adjustable Nozzle: Allows for fine-tuning the spray intensity and pattern for various cleaning needs.

How much pressure do I need for?

The required pressure (PSI) and cleaning power depend on the surface you’re cleaning:

  • Light duty (car washing, outdoor furniture): 1,300-1,800 PSI.
  • Medium duty (patios, fences, decks): 2,000-3,000 PSI.
  • Heavy duty (driveways, brick walls, large equipment): 3,000+ PSI.

Many pressure washers come with adjustable pressure settings to handle different cleaning tasks effectively.

Can a pressure washing damage surfaces?

Yes, a power washer can damage surfaces if used incorrectly. High pressure water can strip paint, dent soft surfaces or even cause structural damage if the pressure is too high or the nozzle is held too close to the surface. Always use the right PSI for the material you’re cleaning and keep a safe distance from delicate surfaces.

To prevent damage, consider using a model with adjustable pressure settings.

How to maintain your pressure washer?

To ensure the durability and smooth operation of a pressure washer:

  • Change the oil as per manufacturer’s instructions.
  • Clean or replace the air filter to ensure good airflow.
  • Inspect and clean the nozzle regularly to prevent clogs.
  • Drain the gas tank if you’re storing the washer for a long time.
  • Check the hoses for leaks or damage and replace them if needed.
  • Follow regular maintenance requirements to keep the washer in optimal condition.

Can I use a pressure washer in cold weather and low water temperature?

You can use a pressure washer in cold weather but it’s more difficult. The water flow rate in the hoses and pump can freeze and damage the equipment. If you plan to use your pressure washer in cold temperatures make sure to winterize it and store it in a warm area when not in use. You can also use anti-freeze solutions for pressure washers.

Some models are designed to use hot water, which can be particularly effective for cleaning in cold weather.
