Professional Performance for Electric Pressure Washers

The Centurion P5 brings precision engineering to the world of electric pressure washers. With 2,500 PSI of power and 2.5 gallons per minute, it's the perfect balance of strength and efficiency for the tough jobs.

It's designed for direct drive electric systems - so it's compact and efficient, and doesn't waste any power along the way. All that energy goes straight into the pump - and that means consistent pressure, smooth operation and long service life.

It's the perfect fit for a lot of setups - from stationary wall-mounts to industrial wash bays and portable electric washers. It's the heart of any reliable cleaning setup - and that's what counts.

Triplex Ceramic Plunger Design

At the heart of the P5 is its triplex plunger system - and that's the best kind of pump you can get. With three precision ceramic plungers, the pump delivers smooth, pulsation-free pressure and holds up to extreme heat and wear.

Each plunger is paired up with high-quality seals and bearings that run smoothly and last a long time. And because ceramic is so tough and resistant to corrosion, the P5 can handle the toughest cleaning jobs with ease.

The result? A pump that lasts, a pump that's low maintenance, and a pump that delivers top performance job after job, year after year.

Direct Drive Efficiency

With direct drive, the pump mounts right onto the electric motor's shaft. No pulleys, no belts - just pure, simple power.

At 3,450 RPM, the P5 crunches that power into water pressure without wasting a single watt. That means a compact setup, a lot less vibration, and a long service life. And that's perfect for applications where efficiency and reliability really count.

Built-In Unloader Valve for Automatic Pressure Control

The P5 comes with a built-in unloader valve, and that's a game-changer. This valve regulates system pressure and keeps the pump safe when you're stopping or starting.

With this built-in feature, you don't need any extra plumbing or fittings. You just get consistent operating pressure, smooth transitions, and long-term protection for the pump and the electric motor.

For pros like you, that means less maintenance, longer up time and dependable performance every single time you use it.

Fixed Soap Injector for Detergent Application

This pump does it all - and that includes applying detergent smoothly and correctly. The fixed soap injector makes sure that your cleaning solution gets to where it's needed, every single time.The fixed chemical injector is designed to draw detergent directly into the water stream during low-pressure operation, making it easy for users to add soaps or degreasers for a real boost in cleaning power. This system is pre-calibrated to give you the right chemical ratios every time, so you can forget about manual mixing.

Perfect for vehicle washing, floor degreasing and equipment cleaning, the P5's soap injector is the ultimate in convenience and consistency — a must-have for any operator who needs their wash cycle to run smoothly and reliably every time.

A Rock-Solid Brass Manifold for Strength and Corrosion Resistance

The brass manifold that serves as the backbone of the P5 is built to last - a durable, corrosion-resistant pressure chamber that can withstand years of high-pressure use, even in harsh environments. Unlike aluminium or composite manifolds, brass will keep its shape even when things get hot or messy.

Centurion's precision-machined brass components ensure a tight seal, consistent pressure output and long term reliability - and when you combine this with ceramic plungers and stainless steel valves, you get a pump that will perform flawlessly in both commercial and light industrial environments.

Thermal Relief Valve: When Things Get Hot

During bypass mode (when the spray gun is not being used), water starts to circulate inside the pump, and it can gradually heat up. To prevent damage, the Centurion P5 comes with a thermal relief valve (85.300.022) that automatically releases the hot water and brings in cooler water to keep the pump at a safe operating temperature.

This simple but essential feature ensures the pump always runs at its best - and protects seals, plungers and valves from heat damage, greatly extending the lifespan of the pump.

Built for Electric Applications

The P5 pump is built from the ground up for electric motor systems, offering quiet, vibration-free operation that's perfect for indoor or noise-restricted environments. Its compact design, light weight (8.8 lbs) and efficient build make it a great fit for wall-mounted units, enclosed wash systems, or portable electric pressure washers.

Operating at 2,500 PSI and 2.5 GPM, the P5 delivers the perfect level of power for cleaning vehicles, equipment, floors and workspaces - without the noise or emissions of gas-powered pumps.

A Cool Running, Low Maintenance Pump

Thanks to its triplex plunger design and oil-lubricated crankcase, the P5 runs cooler and smoother than axial pumps. The 5.5 fl oz oil capacity and 30W non-detergent oil ensure continuous lubrication and reduced friction across all moving parts.

The low-maintenance design means you'll be cleaning in no time - regular oil changes and the odd seal inspection are all that's needed to keep the P5 running like a new one.

This Pump is Designed for the Job

The Centurion P5 is perfect for professional cleaning environments that need reliable performance, lower noise and efficient operation. Its balance of flow and pressure makes it ideal for:

• Car and truck wash bays

• Residential and commercial property maintenance

• Fleet and service vehicle washing

From gentle surface rinsing to tough degreasing, the P5 provides reliable cleaning power in any setting - all while running quietly and efficiently on electric power.

Electric Power: Why it's the Way to Go

The P5's electric compatibility has got some big advantages over gas-driven systems:

• Quiet operation: perfect for indoor or noise-restricted environments

• Zero emissions: a clean, environmentally friendly option for enclosed or sensitive areas

• Low maintenance: no carburetors, spark plugs or fuel system upkeep

• Instant start-up: performance at the touch of a button

Combined with the P5's triplex engineering, these benefits make it one of the most efficient and eco-friendly pump systems available for professional use.

Compact, Industrial Power

At just 8.8 lbs, the P5's small footprint doesn't compromise on performance - its direct-drive design keeps it compact and easy to integrate into tight spaces, while its heavy-duty brass manifold and ceramic plungers deliver industrial-grade strength and reliability.

From portable wash units to wall-mounted cleaning systems, the P5's design makes it the perfect fit for modern electric-powered setups that demand both efficiency and durability.

Built to Last, Backed by Quality

Each pump is thoroughly tested before leaving the factory, so you can expect perfect performance out of the box. The 7 year warranty is a testament to Centurion's confidence in its craftsmanship - giving pros the peace of mind that their equipment will deliver when it counts.

Maintenance Couldn't be Easier

The Centurion P5 is designed to make maintenance a whole lot simpler - just regular oil checks and changes using 30 weight non-detergent oil will keep the engine running smooth while sealed bearings and top-notch seals help stop leaks and pressure loss from becoming a problem.

With built in stuff like an unloader and a fixed chemical injector, theres a lot less outside parts to worry about keeping in working order - and with brass quick-connect fittings you can get your hoses hooked up in a jiffy and know they'll stay that way.

But even when parts do break Centurion replacement parts - including seals, plungers, and valves - are pretty easy to get your hands on, so you can count on years of trouble free service from the P5.
