A Pump That Shows You What It's Made Of

The Centurion P6's triplex ceramic plunger design is the real MVP - delivering the perfect combo of high flow and steady pressure at 4.6 GPM and up to 3,500 PSI. This flow-to-pressure ratio is just right for jobs that need powerful cleaning without the harshness or strain of ultra-high pressure - think washing cars, equipment, floors, and surfaces where precision is just as important as brute force.

Because it's direct drive and electric-powered, the P6 runs as quietly as a whisper and sips power like a champ - minimizing vibration and mechanical loss. With an operating speed of just 1,725 RPM, it means longer component life, less heat buildup, and fewer maintenance cycles over the years.

The CP Difference: Making A Pump That's Built To Last

Every Centurion pump is a result of attention to detail and years of testing. The P6 model carries on CP's legacy of dependability with a design that's all about simplicity, strength, and serviceability.

From its solid brass manifold to its ceramic plungers to its external unloader and adjustable soap injector, every component is engineered to get the job done day in, day out. And that electric direct drive system? It operates more quietly than gas-powered alternatives while keeping consistent torque - a must-have for environments like manufacturing floors, food processing plants, and commercial car washes.

Key Features

A Triplex Ceramic Plunger That Sets The Bar

At the heart of the P6 is a three-piston triplex system with ceramic pistons that come out on top in terms of heat resistance, hardness, and low friction. This design means smooth, efficient strokes and minimal internal wear - perfect for continuous-duty cleaning ops.

Brass Manifold Built To Last

The brass manifold is the real deal - offering superior corrosion resistance, pressure stability, and long-term durability. Brass is the clear choice for its excellent sealing characteristics and ability to withstand repeated pressure cycling without cracking or warping, all while keeping your system leak-free even under sustained load.

An External Unloader That's A Breeze

The external unloader valve makes it easy to fine-tune your system pressure while protecting internal seals and components from overpressure. And with easy access for maintenance and replacement, you've got quick control over cleaning intensity based on the job at hand.

Adjustable Soap Injector To Get The Job Done

With an adjustable chemical injector, operators can actually control how much detergent is being fed directly from the pump - which really makes things simple when moving from one wash cycle to the next. This feature is a big plus when it comes to versatility and just getting the most out of your cleaning chemicals. At the same time, it helps you achieve the perfect clean while also being super efficient in terms of using up less detergent.

Thermal Relief Valve Protection

The thermal relief valve (85.300.023) will actually kick in to save your pump from over-heating when it's sitting idle or bypass mode. When the water temperature starts to get too hot, the valve opens up - which not only lets out some of the hot water, but also brings in some cooler water to stop the seals and plungers from getting damaged by all that heat.

Low-Speed Operation (1,725 RPM)

Unlike those high-RPM gas-powered pumps, the P6 pump spins at a much lower 1,725 RPM, which does a great job at saving wear and tear on all the seals, bearings and plungers. It's also much quieter, making it perfect for indoor use or for places that are really sensitive to noise.

Durable Oil-Lubricated Crankcase

The pump's crankcase actually holds 13.3 fl oz of 30W non-detergent oil, making sure there's a consistent supply of lubrication and also helping to dissipate heat. This really heavy-duty oil bath design does a fantastic job at cutting down on friction, and will make all your components last a lot longer - with easy oil changes being available through a front drain and sight glass so you can keep an eye on the levels.

Designed for Demanding Electric Applications

The Centurion P6 was specifically built to work with electric direct drive motors - and it works super well with 5–7.5 HP motors that are running at 1,725 RPM. This is perfect for places where a gas engine would be impractical or just not wanted, like an indoor car wash bay, a warehouse or even a manufacturing facility.

Some pretty common applications include:

• Car and truck wash stations

• Food processing and packaging facilities

• Cleaning equipment and machinery

• Agricultural washdown systems

• Manufacturing line cleaning

• Facility and floor maintenance

• Mobile car detailing or commercial fleet cleaning

Because the P6 is designed to run quietly and efficiently off an electric motor, it can be used in both stationary and mobile systems without all the noise and emissions worries you get with a gas-powered unit.

Because of that low-RPM electric drive, the combination of ceramic plungers, brass manifold and so on, this pump runs a heck of a lot cooler for longer - protecting all your seals, valves and oil from premature breakdown. The included thermal relief valve is an added layer of protection that makes sure the system stays within safe temperature limits even when it's sitting idle for a long time. The result is a pump that runs quietly, smoothly and reliably, day in and day out.

Easy Maintenance

You don't want any downtime - it's too costly - so we've designed the P6 to be super easy to service. Everything from the unloader to the plungers and seals - all of it is accessible without needing any special tools, making it a breeze for maintenance crews to do regular service without any hassle.

Routine maintenance tips:

1. Just check the oil level from time to time through the sight glass.

2. Replace that oil every 500 hours or as the manufacturer recommends.

3. Have a look at your inlet filters and hoses to make sure they aren't clogged up with debris and causing any cavitation.

4. Give the system a good flush after using chemicals to protect all the internal components.

5. Have a check on your unloader pressure and the thermal relief valve from time to time.

With proper care - and we mean regular care - the Centurion P6 will easily knock up thousands of hours of continuous service without breaking a sweat.

Super Compact and Efficient Design

At just 17 pounds, the P6 is small enough to fit into tight spaces but it still packs a punch when it comes to performance. It also has a 1 1/8" shaft that lets it securely couple to standard electric motor outputs - which means precise alignment and no vibration at all.

The direct drive design eliminates the need for pulleys, belts and all the associated alignment hassle - which means there's a lot less mechanical losses and it's easier to assemble too. For all you OEMs and equipment builders, this is a real winner - it means a cleaner, more efficient design with fewer moving parts to maintain.

Getting the P6 installed is super easy, thanks to that standard 1 1/8" shaft and compatible bolt pattern. Whether you're mounting it onto an electric motor or integrating it into some custom cleaning station, setup is quick and painless.

Installation Steps:

1. Bolt the pump down onto a stable mounting base thats been designed to dampen out any vibrations that might develop

2. Get the motor shaft and the keyway lined up with the pump shaft so that everything is aligned.

3. Tighten those set screws and then double-check the alignment to make sure you've got some stability - you dont want the whole thing vibrating apart on you.

4. Connect up the 3/4 inch GHF inlet and the 3/8 inch brass QC discharge fittings - the ones youll be using to channel the water and so on.

5. Fill the crankcase up with 13.3 fluid ounces of 30 weight non-detergent oil - dont skimp on the lubrication.

6. Once you've got it all hooked up test for any leaks and make sure the pressure is consistent

Once the P6 is installed, its virtually maintenance-free apart from the occasional check on the oil and seals - and that means you're looking at a long-lasting and efficient solution for your commercial electric pressure washer system
